= Rationale =
As the urbanization processes have speeded up around the world, every natural element nearby the [https://en.wikipedia.org/wiki/Metropolitan_area metropolitan areas] often end up being sacrificed for the sake of economy purposes and '''Siutghiol Lake''' is no stranger to that. Covering an area nearly as broad as the hostile city in the south ([https://en.wikipedia.org/wiki/Constan%C8%9Ba '''Constanța''']), the lake has suffered of habitats degradation due to irrational tourism, nearby factories, illegal building procedures and lack of interest from the local administration. It is very important to preserve the area, as the lake serves as an important migratory route of the birds through the [https://en.wikipedia.org/wiki/Via_Pontica '''Via Pontica'''] and the [https://www.academia.edu/2513619/A_conservationist_approach_to_the_eligibility_of_Dobrogea_Romania_as_target_area_for_exploitation_of_windresources '''Sarmatian Route''']. The aim of this study is to cover every important aspect which led to the deconstruction of something that once was a hospitable environment.

== Geomorphology, typologies and dynamics of water areas ==
Located in [https://en.wikipedia.org/wiki/Dobruja '''Dobrogea'''], northern of the Constanța municipality, Siutghiol Lake (sütgöl meaning „milk lake” in Turkish) has an area of approximately '''20 km²''' filled with '''69.6 million m³''' of water (Telteu, Zaharia, 2012), reaching the depth of 18 meters (according to Gâștescu) and a '''7.82 meters depth''' according to more recent measurements. Geomorphologically speaking, the lake '''used to be a bay''' in the past, directly communicating with the [https://en.wikipedia.org/wiki/Black_Sea Black Sea], but because of the wave action, abrasion, accumulation, local winds and marine currents, a 300-400 meters width and 9 km long [https://en.wikipedia.org/wiki/Spit_(landform) '''sandspit'''] was formed, where the [https://en.wikipedia.org/wiki/Mamaia Mamaia] touristic resort lies now.

The local depressions were shaped during the later [https://en.wikipedia.org/wiki/Jurassic Jurassic] and early [https://en.wikipedia.org/wiki/Quaternary Quaternary] times (100-160 million years ago) all these mainly because of the '''marine abrasion'''. These days, Siutghiol communicates with the Black Sea through [https://wave.hfwu.de/index.php?title=Lacul_T%C4%83b%C4%83c%C4%83riei_Team_1_Living_Lab_2021 Tăbăcarie Lake] (which is 20 km southward) through anthropic canals. It also supplies the upper lakes of Tașaul and Corbu with freshwater through canals (some sources claim that the water supply has been stopped in the past years). Nearby the western shore of Siutgiol lies a 2.6 ha '''island''' of limestone composition named after the roman poet [https://en.wikipedia.org/wiki/Ovid '''Pūblius Ovidius Nāsō'''] who apparently wrote some of his poetry on this island as he was exiled, however this is just a myth to attract tourism in the area.

</gallery>

The most common types of water in the area tend to be overshadowed by the presence of the Black Sea, however [https://en.wikipedia.org/wiki/Lagoon lagoons] and [https://en.wikipedia.org/wiki/Liman_(landform) limans] are still a very typical sight of western Dobrogea. '''The genesis''' of the lakes is natural, but some anthropic changes occurred in the past centuries for a better function of the territory (canals, dams, bridges, roads and so on) action that speeded up the urbanization process. '''Natural rivers''' in the are are rare to be found because of the lack of high geomorphological units nearby (the closest geomorphological unit to a [https://en.wikipedia.org/wiki/M%C4%83cin_Mountains mountain range] being in northern part of Dobrogea), however there are plenty of canals including the [https://en.wikipedia.org/wiki/Danube%E2%80%93Black_Sea_Canal '''Danube-Black Sea Canal'''] built to shorten the trade route on the Daube River by 400 km. '''Wet lands''' can be found in the proximity of the limans and the shore and serve as a habitat for the local species, however most of them started to be replaces with parking lots, buildings or landfills (Palazu Mare). In Tăbăcărie Lake, a part of the '''wastewater''' of the city of Constanța is discharged, which obviously led to mass losses of the natural biotope in the area as many birds species don't stop by the lake anymore on their migratory route.

Despite the fact that most of the water supplies in the Romanian lakes come directly from rainfalls or rivers, the main input of the western Dobrogean lakes are the [https://en.wikipedia.org/wiki/Groundwater '''groundwaters'''] which allows the water level to be stable all year round, even if they're no longer connected to the Black Sea. The [https://en.wikipedia.org/wiki/Bedrock bedrock] of Siutghiol is mainly formed from [https://en.wikipedia.org/wiki/Karst karst] which allows an optimal interaction with the groundwaters. There are '''no tributaries''' as most of the rivers in this region drain directly in the Black Sea or the Danube. The lack of '''annual precipitations''' (around 400 mm) aren't enough to supply the Siutghiol Lake with freshwater at a constant rate, so other sources are needed.

The [https://en.wikipedia.org/wiki/Floodplain floodplain] area is extended in the southern part of the Constanța Municipality, but when it comes to the Siutghiol Lake, the '''Mamaia Sandspit''' is the most vulnerable area to floods alongside the northern shore of the lake, where the slopes are low to non-existing. However, because of '''recent rehabilitation efforts''' (dams construction, [https://en.wikipedia.org/wiki/Tetrapod_(structure) tetrapods], etc.) the flood chances are very low as long as the ocean level remains stable. The Siutghiol’s catchment areas is estimated to cover an area of '''71.6 km²'''.

Due to the different water flow input in the local lakes and the anthropic needs that arose in the use of these lakes after 1950, several '''connecting canals''' were built between these lakes. Thus, through these canals, water transfers take place from Siutghiol Lake to Tăbăcăriei and from it to the sea, and also from Siutghiol through a pipeline to Tașaul. Subsequently, due to the increase in water consumption in Siutghiol and the regulation of leaks between Tașăul and Gargalâc and discharges into the sea (for Lake Gargalâc) this pipeline was closed in 1967. Level variations and climatic characteristics are very well reflected in the hydrological balance of Lake Siutghiol as over the years, the average lake level fluctuated from 115 cm to 225 cm and even more during the flood event.

Because of the relatively low [https://en.wikipedia.org/wiki/Elevation elevation] level, especially in northern part of Dobrogea, '''floods''' have been common for most of the time. However, as the time passed by and humanity developed engineering systems to stop the flooding phenomena to occur, the incidents slowed down or stopped. The lack of precipitations in the area also comes close by regarding this matter. For preventing future possible floods and the '''erosion caused by the waves action and by marine currents''', the local administration has placed [https://en.wikipedia.org/wiki/Tetrapod_(structure) '''tetrapods'''] near the shore in the proximity of human settlements. Despite all of this, because of the heavy rainfalls that sometimes occur in the region during the summertime, back in '''2004''' the people living nearby the coast have experienced floods for one day (28 August) and no other significant flood has been reported ever since. The only regions exposed to this matter are far from human settlements (at least in the southern Dobrogea). The '''plateau's''' geomorphological features prevent the city from experiencing such unfortunate events. However, the study area is more vulnerable to this due to recent '''climate changes''' and rise of the world oceans level which will affect the Black Sea as well, despite being a '''relatively guarded sea'''. The bay barrier of Mamaia is flat and doesn't even reach 2 meters height so it is very likely that in the future it might get back underwater if no action is taken.

== Water as a living space ==
By implementing the [https://en.wikipedia.org/wiki/Natura_2000 Natura 2000] network in Romania, Siutghiol Lake became a protected area- code [https://natura2000.eea.europa.eu/Natura2000/SDF.aspx?site=ROSPA0057 ROSPA0057]. 

'''The Ministry of Environment''' is responsible for the management of this site, through the National Agency for Protected Areas. Currently, there is no managament plan for the lake but even if it is not mandatory to have one, its absence contributes to some serious management and conservation problems. 

[https://www.birdlife.org/europe-and-central-asia/partners/romania-%E2%80%93-romanian-ornithological-society-sor-birdlife-romania The Romanian Ornithological Society] assigned the lake as an [https://www.birdlife.org/worldwide/programme-additional-info/important-bird-and-biodiversity-areas-ibas IBA] according to the following [http://datazone.birdlife.org/site/ibacritsubreg criteria] ellaborated by [https://www.birdlife.org/worldwide/partnership/about-birdlife BirdLife International]: C1, C2, C4.
During the migration season, the lake hosts more than 20.000 aquatic birds, thing that makes it a possible candidate for [https://www.ramsar.org/about-the-convention-on-wetlands-0 RAMSAR].
Siutghiol Lake houses important categories of protected species: 32 species mentioned in [https://ec.europa.eu/environment/nature/legislation/birdsdirective/index_en.htm The Birds Directive]-[https://ec.europa.eu/environment/nature/conservation/wildbirds/threatened/index_en.htm Annex 1], 43 migrating species listed in the annexes of the Convention on Migratory Species (CMS) and 4 globally endangered species. 

Habitats: N06- continental freshwaters, N07-wetlands N23-artificial land 

Siutghiol Lake is a [https://en.wikipedia.org/wiki/Lagoon lagoon] with a particular economic (industry and agriculture), therapeutic and touristic importance. Because of the intense anthropic activity through tourism, water sports, fishing, road traffic and inhabited areas ([https://en.wikipedia.org/wiki/Mamaia Mamaia Resort], [https://en.wikipedia.org/wiki/Constan%C8%9Ba Constanta], [https://en.wikipedia.org/wiki/Ovidiu Ovidiu]) there is a great negative impact on the lake`s flora and fauna. 

The greatest danger the lake faces is the pollution. Some ways of polluting are the artificial water intake from the Poarta Alba-Midia Navodari canal, the artificial water intake through the sewerage network (wastewater treatment plants, pumping stations and water channels) and artificial water leaks that enter the lake through tributary valleys. Some other causes of the biologicaly distress of the lake is the growing human population and urban development, abusive fishing, intensive road traffic, hunting and touristic activities.
Because of these reasons, the terrestrial bird species that used to live near the lake and are protected by the Natura 2000 network do not have favorable habitats anymore. 

Fish movement from Siutghiol Lake to Tabacarie Lake and back is not restricted by anthropic elements. The life of fish is still affected by water pollution and street lights which influences their behaviour. 

Electrometric measurements and underwater research in the area showed the existence of some strong water sources under the lake. The lake is supplied with fresh water by 3 underground springs with a great flow which keep the water of the lake clear. The water quality of the lake fits in the legal limits approved. The absence of these springs would prove how polluted the lake is by people.

== Blue and Green Infrastructure ==

In order to be able to understand the term '''BGI''' ('''Blue and Green Infrastructure''' ) within the study area, we must take into account the current network of the green infrastructure of Constanta and Mamaia resort. The elements that have a major potential in a green-blue infrastructure are green, eco-friendly landscapes such as green areas, especially parks with favorable vegetation for the climatic conditions and '''technologies''' whose main purpose is to reduce the consumption of industrially produced, obsolete and polluting energy. These green areas are '''buffer areas''', which ensure the integrity of natural habitats. At the moment, from ours point of view , the chaotic extension of the built space and the destruction of the natural areas are driving the blue green infrastructure in a critical point. And this is all because there is no specialized management to deal with this problems, or with the implementation of new projects which could target reconversion solutions for current buildings and functional spaces.

= Water as a cultural space =
== Land use and water==
It's safe to say that the study area covers a wide '''variety of land and water use'''. Around the lake, the urban areas take the most part of the land and serve as either a residential purpose (Ovidiu, Palazu Mare, Constanța) or an entertainment one (on the eastern shore - Mamaia). There are some very small '''green urban areas''' which count the most to the total green region. The industrial or commercial units sit in Siutghiol's proximity as well and as mentioned before, some of their waste is disposed in the lake with little to none consequences. As for the '''natural side''', there are a few inland marshes which don't cover a big part, a little area dedicated for pastures, the Danube-Black Sea Canal in the north and a transitional woodland-shrub area. Right before the northern entrance to the Constanța Municipality, there is a '''mineral extraction site''' which is still exploited to this day. The rest of the area is covered by the '''agriculture''' branch which extents to the nearby cities and it's a common sight in Dobrogea. The road network is not as developed as you would expect, but it is definitely present as the '''A2 Highway''' (also known as The Highway of the Sun) crosses the west side of the lake.

The '''forest''' zones are far gone as you can barely find any trees within the study area (there are a few between Ovidiu and Palazu Mare or in the green urban areas) and not because of the climate type or soil compositions, but because of high '''deforestation actions''' in the past decades. Some industrial units don't work anymore and there is a changing tendency to commercial units instead. The wild beaches that once were on the sandspit were replaced by the touristic resorts which is constantly expanding. The land and water use will definitely change in the near future as the urban areas extend in a worrying manner and the agriculture is slowly fading away. Authorities will most likely use every inch of the coastline if no action is being taken anytime soon. Despite its natural genesis, the Siutghiol Lake has definitely met high anthropic interventions as the time passed by and you can see its older days remains only in a few places now.

== Cultural and spatial typologies of water areas ==
With the formation of the Mamaia estuary, due to the closure of the Black Sea bay, along it, on one side and on the other, numerous constructions appeared. On the side with Lake Siutghiol, a series of '''hotel and restaurant units''' were built, as well as '''recreational areas'''. From the perspective of the natural environment, Siutghiol evolved at the same time as Lake Tăbăcăriei, contributing to its supply of water, through the canal that connects them. The presence of the lake favored the development of the tourist infrastructure, due to the landscape it offers, but it also influenced the urban configuration of the city, by building residential centers and by developing the street plot. Regarding the cultural part of the region, it is found only in the '''campus area''', through the presence of Ovidius University, and in the area of [https://en.wikipedia.org/wiki/Mamaia Mamaia Resort], on the lake side, these characteristics are missing, but are offset by those on the sea side, where there is a '''casino'''.

In general, water areas create attractive points at the level of a city, as they are the main agreement area for citizens. As an example for the city of Constanța, we are talking about Lake Siutghiol and Lake Tăbăcăriei. If we look at the water area as an essential resource for development, Lake Siutghiol has been an important area since the distant past, on the shores of which various buildings have been erected, both '''residential, commercial, recreational, cultural and sports areas'''. Lake Siutghiol plays an important role in the urban development of the city, as it offers the possibility to carry out activities for leisure and relaxation, such as '''fishing, walks around the lakes and boat trips'''. The increasing accentuation with built spaces, of the area between Siutghiol Lake and Mamaia Boulevard creates the idea that '''the place is not for people''', because the investors who did not take into account the demographic side of a city.

== Sacred spaces and heritage ==
The Black Sea coast has been occupied by many civilizations over the time (Greeks, Romans, Ottomans and so on) so there is no surprise that they left a '''generous cultural heritage''' behind them. There is no well preserved archaeological site around the Siutghiol Lake, however you can still find some Paleolithic settlements in [http://ran.cimec.ro/sel.asp?codran=60525.01 Mamaia Sat] and Ovidiu that are set to be exposed soon by the archaeologists. You can also find a [http://ran.cimec.ro/sel.asp?codran=60696.01 Roman-Byzantine fortifications] on the western side of the lake, on a small [https://en.wikipedia.org/wiki/Promontory promontory] of the [https://en.wikipedia.org/wiki/Ovidiu Ovidiu] city and another one in Palazu Mare. There are no sites on the Mamaia sand-belt discovered most likely because it is a relatively new geomorphological formation and there was no point in building settlements on vulnerable and exposed land.

The irrational tourism, lack of investments into national cultural heritage preservation and misguided excavation actions by unqualified staff lead to the sites being forgotten in the local touristic routes and little to no attention is given to them. Because the cultural heritage is '''unable to recover once damaged''', any rehabilitation action done by the archaeologists is '''highly restricted'''. The [https://en.wikipedia.org/wiki/Archaeological_tourism '''archaeo-tourism'''] (tourists who practice thematic cultural routes) is often overshadowed in Dobrogea by the other local sights such as the [https://en.wikipedia.org/wiki/Danube_Delta Danube Delta] and [https://en.wikipedia.org/wiki/M%C4%83cin_Mountains Măcin Mountains] in the north, or the resorts in the south. However, despite not living on the high profile, it emerges only when it's needed to and if the right effort is put into it, then it can serve as a great '''economic resource''' to the community.

== Visual appearance and landscape narrative ==
[https://fr.wikipedia.org/wiki/Miron_Costin Miron Costin] claims the existence of a lake in the counties near the [https://en.wikipedia.org/wiki/Dniester Dniester river], called either ''Owidowo, Vidovul, Ovidiului Lake, Lagoul Ovidouloui, Vidovo Lacus, Ovidovo Lacus'' or ''Vidovo Lake'' in different cartographical documents from various centuries. Many chroniclers, writers and poets have been writing about the Siutghiol Lake since the 16 th century. The lake was often mentioned in historic documents as well as travel guides and poems. Those who wrote about the lake often associated it with the name of the roman poet, Pūblius Ovidius Nāsō because, as the legend says, he was exiled by Emperor Augustus in 8 AD on a small island (link insula) located in Siutghiol Lake.

'''Local legend''': Once upon a time, where you can find '''Siutghiol Lake''' nowadays, there was a village full of bad people. Strangers were not welcomed there. On a festive day, when the villagers were celebrating in their homes, a man sneaked into the village. He asked many people to be let to stay overnight but without success. Seeing that no one is welcoming him, he decided to head to the edge of the village. He found there a small house made of stone where an old woman lived. She, unlike her neighbors, was kind and let the stranger stay as long as he wished to. The old woman was worried as she did not have anything to feast the man with. The traveler told her to put some manure in the furnace and so she did. The woman was astonished when she opened the furnace door as she found there an enormous bread that would become whole again after each bite. The next day, as the traveler left, water came out of nowhere and the village sunk. Everything was gone. Only the stone house remained and a crystal-clear lake formed.

The water is the central focus of this area along with the flora and fauna that depends on it on a long term, like the local plants and animals do, as well as on short-term, like the migratory birds that nest in this area.

== Accessibility and usability ==
The main access routes to reach the Siutghiol Lake by car are the '''Ovidius University campus''' in the south, , the whole '''Mamaia and Aurel Vlaicu Boulevard''' – not to mention the open space sand barrier where the Mamaia Resort lies - plus secondary thoroughfares such as Ovidius University, Jade and Border Alley, as well as other unmarked roads or natural ones.
As mentioned before, the Siutghol Lake is accessible in certain areas such as the Mamaia Resort, or - on the southern shoreline - by '''Aqua Magic''', part of the area near the Ovidius University. But the accessibility can also refer to areas where the lake can be admired in all of its glory, with or without the built infrastructure to serve the tourists such as hotels or restaurants. In terms of spatial obstacles, the constructions in general prevent the development of other activities along the lake shore - a matter easily noticed on the eastern coast where the '''buildings density''' is higher than it should be. Also, the lake has certain areas in Mamaia where it is not organized at all and presents possible dangers to the local biodiversity because of the '''household wastes'''.

The area of the Siutghiol Lake is mainly used by the local '''investors''', who want to extend the resort as much as possible, in order to exploit the area economically. Of course, tourists are a common typology to be seen around the lake. Lately, this area has been used intensively for the development of '''mass tourism''', by building hotels, restaurants, parks and other touristic sights. Another purpose for which this area is used is for leisure, boat trips, water sports, and in addition to these, fishing also takes place, an activity practiced by both amateurs and professionals. The area of Lake Siutghiol, belonging to the resort of Mamaia is used to own the JT Watersports water park, and it’s open only during summertime, next to being located the only floating restaurant in Mamaia, which is under construction. On the Ovidiu Island not many things are going on, there is a little restaurant and a wharf for the tourists.

== Community Mapping ==
What is to be mapped here?
*'''Social groups''' from within the community, for example the youth, kids, students, parents, the retired etc. Typically, these groups have specific needs, which you can also make explicit on the map. These people might not be organized in any way, but they are usually present in the context you are observing
* '''Local stakeholder groups''': these groups are organized in one or the other way. They only exist within the community context you are observing. For example: the local community center, local churches, local interest groups, the landowners, small businesses and retailers
*'''External stakeholder groups''' are not necessarily present in the environment you are observing, but they may have strong stakes and interests. These can be local authorities, politicians, associations, care services etc.
* For each group, you may identify their '''needs, objectives, power and capacities'''
* You may also identify gaps and '''power conflicts'''
* Please try to redepict these elements in an integrated way and in relation to your water landscape. What is the relationship between these groups? Are they close or distanced from each other? Who is more powerful? Which voices are hardly heard? Do they have any shared concerns?

= Possible Futures =
For the risks map, we took into consideration '''five main problems''' that occur within our study area. The most negative part found here is the '''overpopulated shore''' of the lake on the eastern side where the Mamaia Resort is located, full of high buildings which are full with tourists during summertime. In the southern part there is the Constanta Municipality which also impacts the lake's ecosystem because of the '''huge amount of cars''' crossing the lake every day.
All this high population density leads to another problem in the area which is the '''household waste''' found at nearly every corner. A few volunteering institutes (one of them being the '''Ovidius University''' itself) have cleaned some of the areas, however the garbage always gathers overtime because of the lack of education. 
The '''industrial areas''' around the lake are also a top contributor for the pollution as there is little to none governmental action to ban the waste disposal from the factories in the water. Some other risky factors might include things like the possible '''landslides''' that might occur because of the common cliff structures and the areas exposed to '''floods''' which, so far, are not put in danger, however considering the climate change and the rise of the ocean level, this might be a problem that the locals might will face sooner than anticipated.

As for the future potential map, we took into consideration the implementation of '''green roofs''' on the Mamaia sand-belt since the buildings density is already high, a biomass power plant in the north which basically burns waste and makes eco-energy in the process, a '''marine lock''' also in the north for possible floods and a '''photovoltaic park''' between Ovidiu and Constanța which would supply both locations with solar energy for as much as it can provide, especially during summertime when the tourism is at its peak.
This diagram refers to the forces ('''driving forces''') which manifest a pressure above the living state of an natural system. This pressure result in an '''impact''' which is mostly bad and his main result is to destroy the natural resilience. The main driving forces which take place in this area are the political environment with his legislation, the process of energy consumption, the tourism, farming and the industry. This forces shapes the areal and forces it at some great pressure. The '''pressure domain''' , as you can see in the graph is formed by the '''uncontrolled expansion''' of the built space, '''poaching''', '''lack of green infrastructure''' and the '''exhaustion of the natural resources'''. These are a few examples, the most relevant and the most visible things you can discover with your own eyes in the surroundings of the Siutghiol Lake and in the city of Constanta. 

Regarding the state of the lake, first of all, Siutghiol is included in the category of '''Natura 2000 protected sites''', being a '''lagoon''', whose water is fresh. It has an alkaline pH, between 8 and 9, and in terms of phosphorus content, which has a tendency to increase, the lake tends to become '''eutrophic'''. It is known to have '''31 species''' '''of protected birds''' ,both nesting and migratory. The habitat types in the lake are mostly psammophilic and calciphilic. 

Human's activities always have an impact on nature and biodiversity because people change the place where they live as they please. The most important impacts resulting from the pressures are pollution, caused by the uncontrolled expansion of buildings and the lack of green infrastructure. Reduced biodiversity, the growing number of buildings has negative effects on the life of the species, but poaching is a determining factor, their amount of light is reduced and their habitats are destroyed. Increasing resource consumption is an important impact, as it reduces the natural environment and habitats of the species present. However, the big problem is exceeding the support capacity of the environment and decreasing the '''optimal''' standard of living, which influences both the environment and the population. 

In terms of '''solutions''', surveillance of the area with cameras and drones can solve the problem of poaching, reconversion programs of existing buildings in some that include green infrastructure, such as green roofs, can reduce the lack of clean infrastructure, but also reduce pollution in a small measure.
'''Green City''' - is a positive scenario for the lake`s neighborhood, which involves the use of solar panels, forest cords, green roofs and wind farms around the lake. It`s a good idea to develop the shores of the water in an eco style. 

'''Urbanization''' - this is a negative scenario, which involves a high urbanization, in particular on the east shore, in Mamaia and Năvodari. This constructions, extended irrational, will lead to a huge anthropogenic pressure on the fauna and flora. 

'''Invasive species''' - this has also a negative impact on the faunal & floral balance, and in this case, our water landscape will have big problems with the support of life. 

'''Drought'''-the lake dries up - If this happens, all species who live here, both in waters of the lake and on its shores will disappear. That can be the end of our water landscape and, after all, the desertification process will reach high levels in this area. 

'''Floods''' - a natural hazard, which happens time to time in all over the world, in some particular conditions. This scenario will lead to water pollution and also will cause serious damage to agriculture and settlements near the lake. 

'''Nuclear explosion''' - which is probably the worse case scenario for the entire region, including our lake. We all know what happened to Cernobîl, in 1986, where hundreds of humans and also animals died after the exposure t the radiation, and this process can continue many years after the explosion moment.

= Rationale =
As the urbanization processes have speeded up around the world, every natural element nearby the [https://en.wikipedia.org/wiki/Metropolitan_area metropolitan areas] often end up being sacrificed for the sake of economy purposes and '''Siutghiol Lake''' is no stranger to that. Covering an area nearly as broad as the hostile city in the south ([https://en.wikipedia.org/wiki/Constan%C8%9Ba '''Constanța''']), the lake has suffered of habitats degradation due to irrational tourism, nearby factories, illegal building procedures and lack of interest from the local administration. It is very important to preserve the area, as the lake serves as an important migratory route of the birds through the [https://en.wikipedia.org/wiki/Via_Pontica '''Via Pontica'''] and the [https://www.academia.edu/2513619/A_conservationist_approach_to_the_eligibility_of_Dobrogea_Romania_as_target_area_for_exploitation_of_windresources '''Sarmatian Route''']. The aim of this study is to cover every important aspect which led to the deconstruction of something that once was a hospitable environment.

== Geomorphology, typologies and dynamics of water areas ==
Located in [https://en.wikipedia.org/wiki/Dobruja '''Dobrogea'''], northern of the Constanța municipality, Siutghiol Lake (sütgöl meaning „milk lake” in Turkish) has an area of approximately '''20 km²''' filled with '''69.6 million m³''' of water (Telteu, Zaharia, 2012), reaching the depth of 18 meters (according to Gâștescu) and a '''7.82 meters depth''' according to more recent measurements. Geomorphologically speaking, the lake '''used to be a bay''' in the past, directly communicating with the [https://en.wikipedia.org/wiki/Black_Sea Black Sea], but because of the wave action, abrasion, accumulation, local winds and marine currents, a 300-400 meters width and 9 km long [https://en.wikipedia.org/wiki/Spit_(landform) '''sandspit'''] was formed, where the [https://en.wikipedia.org/wiki/Mamaia Mamaia] touristic resort lies now.

The local depressions were shaped during the later [https://en.wikipedia.org/wiki/Jurassic Jurassic] and early [https://en.wikipedia.org/wiki/Quaternary Quaternary] times (100-160 million years ago) all these mainly because of the '''marine abrasion'''. These days, Siutghiol communicates with the Black Sea through [https://wave.hfwu.de/index.php?title=Lacul_T%C4%83b%C4%83c%C4%83riei_Team_1_Living_Lab_2021 Tăbăcarie Lake] (which is 20 km southward) through anthropic canals. It also supplies the upper lakes of Tașaul and Corbu with freshwater through canals (some sources claim that the water supply has been stopped in the past years). Nearby the western shore of Siutgiol lies a 2.6 ha '''island''' of limestone composition named after the roman poet [https://en.wikipedia.org/wiki/Ovid '''Pūblius Ovidius Nāsō'''] who apparently wrote some of his poetry on this island as he was exiled, however this is just a myth to attract tourism in the area.

<gallery caption=" " widths="600px" heights="450px" perrow="5">

</gallery>

The most common types of water in the area tend to be overshadowed by the presence of the Black Sea, however [https://en.wikipedia.org/wiki/Lagoon lagoons] and [https://en.wikipedia.org/wiki/Liman_(landform) limans] are still a very typical sight of western Dobrogea. '''The genesis''' of the lakes is natural, but some anthropic changes occurred in the past centuries for a better function of the territory (canals, dams, bridges, roads and so on) action that speeded up the urbanization process. '''Natural rivers''' in the are are rare to be found because of the lack of high geomorphological units nearby (the closest geomorphological unit to a [https://en.wikipedia.org/wiki/M%C4%83cin_Mountains mountain range] being in northern part of Dobrogea), however there are plenty of canals including the [https://en.wikipedia.org/wiki/Danube%E2%80%93Black_Sea_Canal '''Danube-Black Sea Canal'''] built to shorten the trade route on the Daube River by 400 km. '''Wet lands''' can be found in the proximity of the limans and the shore and serve as a habitat for the local species, however most of them started to be replaces with parking lots, buildings or landfills (Palazu Mare). In Tăbăcărie Lake, a part of the '''wastewater''' of the city of Constanța is discharged, which obviously led to mass losses of the natural biotope in the area as many birds species don't stop by the lake anymore on their migratory route.

Despite the fact that most of the water supplies in the Romanian lakes come directly from rainfalls or rivers, the main input of the western Dobrogean lakes are the [https://en.wikipedia.org/wiki/Groundwater '''groundwaters'''] which allows the water level to be stable all year round, even if they're no longer connected to the Black Sea. The [https://en.wikipedia.org/wiki/Bedrock bedrock] of Siutghiol is mainly formed from [https://en.wikipedia.org/wiki/Karst karst] which allows an optimal interaction with the groundwaters. There are '''no tributaries''' as most of the rivers in this region drain directly in the Black Sea or the Danube. The lack of '''annual precipitations''' (around 400 mm) aren't enough to supply the Siutghiol Lake with freshwater at a constant rate, so other sources are needed.

The [https://en.wikipedia.org/wiki/Floodplain floodplain] area is extended in the southern part of the Constanța Municipality, but when it comes to the Siutghiol Lake, the '''Mamaia Sandspit''' is the most vulnerable area to floods alongside the northern shore of the lake, where the slopes are low to non-existing. However, because of '''recent rehabilitation efforts''' (dams construction, [https://en.wikipedia.org/wiki/Tetrapod_(structure) tetrapods], etc.) the flood chances are very low as long as the ocean level remains stable. The Siutghiol’s catchment areas is estimated to cover an area of '''71.6 km²'''.

Due to the different water flow input in the local lakes and the anthropic needs that arose in the use of these lakes after 1950, several '''connecting canals''' were built between these lakes. Thus, through these canals, water transfers take place from Siutghiol Lake to Tăbăcăriei and from it to the sea, and also from Siutghiol through a pipeline to Tașaul. Subsequently, due to the increase in water consumption in Siutghiol and the regulation of leaks between Tașăul and Gargalâc and discharges into the sea (for Lake Gargalâc) this pipeline was closed in 1967. Level variations and climatic characteristics are very well reflected in the hydrological balance of Lake Siutghiol as over the years, the average lake level fluctuated from 115 cm to 225 cm and even more during the flood event.

Because of the relatively low [https://en.wikipedia.org/wiki/Elevation elevation] level, especially in northern part of Dobrogea, '''floods''' have been common for most of the time. However, as the time passed by and humanity developed engineering systems to stop the flooding phenomena to occur, the incidents slowed down or stopped. The lack of precipitations in the area also comes close by regarding this matter. For preventing future possible floods and the '''erosion caused by the waves action and by marine currents''', the local administration has placed [https://en.wikipedia.org/wiki/Tetrapod_(structure) '''tetrapods'''] near the shore in the proximity of human settlements. Despite all of this, because of the heavy rainfalls that sometimes occur in the region during the summertime, back in '''2004''' the people living nearby the coast have experienced floods for one day (28 August) and no other significant flood has been reported ever since. The only regions exposed to this matter are far from human settlements (at least in the southern Dobrogea). The '''plateau's''' geomorphological features prevent the city from experiencing such unfortunate events. However, the study area is more vulnerable to this due to recent '''climate changes''' and rise of the world oceans level which will affect the Black Sea as well, despite being a '''relatively guarded sea'''. The bay barrier of Mamaia is flat and doesn't even reach 2 meters height so it is very likely that in the future it might get back underwater if no action is taken.

== Water as a living space ==
By implementing the [https://en.wikipedia.org/wiki/Natura_2000 Natura 2000] network in Romania, Siutghiol Lake became a protected area- code [https://natura2000.eea.europa.eu/Natura2000/SDF.aspx?site=ROSPA0057 ROSPA0057]. 

'''The Ministry of Environment''' is responsible for the management of this site, through the National Agency for Protected Areas. Currently, there is no managament plan for the lake but even if it is not mandatory to have one, its absence contributes to some serious management and conservation problems. 

[https://www.birdlife.org/europe-and-central-asia/partners/romania-%E2%80%93-romanian-ornithological-society-sor-birdlife-romania The Romanian Ornithological Society] assigned the lake as an [https://www.birdlife.org/worldwide/programme-additional-info/important-bird-and-biodiversity-areas-ibas IBA] according to the following [http://datazone.birdlife.org/site/ibacritsubreg criteria] ellaborated by [https://www.birdlife.org/worldwide/partnership/about-birdlife BirdLife International]: C1, C2, C4.
During the migration season, the lake hosts more than 20.000 aquatic birds, thing that makes it a possible candidate for [https://www.ramsar.org/about-the-convention-on-wetlands-0 RAMSAR].
Siutghiol Lake houses important categories of protected species: 32 species mentioned in [https://ec.europa.eu/environment/nature/legislation/birdsdirective/index_en.htm The Birds Directive]-[https://ec.europa.eu/environment/nature/conservation/wildbirds/threatened/index_en.htm Annex 1], 43 migrating species listed in the annexes of the Convention on Migratory Species (CMS) and 4 globally endangered species. 

Habitats: N06- continental freshwaters, N07-wetlands N23-artificial land 

Siutghiol Lake is a [https://en.wikipedia.org/wiki/Lagoon lagoon] with a particular economic (industry and agriculture), therapeutic and touristic importance. Because of the intense anthropic activity through tourism, water sports, fishing, road traffic and inhabited areas ([https://en.wikipedia.org/wiki/Mamaia Mamaia Resort], [https://en.wikipedia.org/wiki/Constan%C8%9Ba Constanta], [https://en.wikipedia.org/wiki/Ovidiu Ovidiu]) there is a great negative impact on the lake`s flora and fauna. 

The greatest danger the lake faces is the pollution. Some ways of polluting are the artificial water intake from the Poarta Alba-Midia Navodari canal, the artificial water intake through the sewerage network (wastewater treatment plants, pumping stations and water channels) and artificial water leaks that enter the lake through tributary valleys. Some other causes of the biologicaly distress of the lake is the growing human population and urban development, abusive fishing, intensive road traffic, hunting and touristic activities.
Because of these reasons, the terrestrial bird species that used to live near the lake and are protected by the Natura 2000 network do not have favorable habitats anymore. 

Fish movement from Siutghiol Lake to Tabacarie Lake and back is not restricted by anthropic elements. The life of fish is still affected by water pollution and street lights which influences their behaviour. 

Electrometric measurements and underwater research in the area showed the existence of some strong water sources under the lake. The lake is supplied with fresh water by 3 underground springs with a great flow which keep the water of the lake clear. The water quality of the lake fits in the legal limits approved. The absence of these springs would prove how polluted the lake is by people.

== Blue and Green Infrastructure ==

In order to be able to understand the term '''BGI''' ('''Blue Green Infrastructure''' ) within the study area, we must take into account the current network of the green infrastructure of Constanta and Mamaia resort. The elements that have a major potential in a green-blue infrastructure are green, eco-friendly landscapes such as green areas, especially parks with favorable vegetation for the climatic conditions and '''technologies''' whose main purpose is to reduce the consumption of industrially produced, obsolete and polluting energy. These green areas are '''buffer areas''', which ensure the integrity of natural habitats. At the moment, from ours point of view , the chaotic extension of the built space and the destruction of the natural areas are driving the blue green infrastructure in a critical point. And this is all because there is no specialized management to deal with this problems, or with the implementation of new projects which could target reconversion solutions for current buildings and functional spaces.

= Water as a cultural space =
== Land use and water==
It's safe to say that the study area covers a wide '''variety of land and water use'''. Around the lake, the urban areas take the most part of the land and serve as either a residential purpose (Ovidiu, Palazu Mare, Constanța) or an entertainment one (on the eastern shore - Mamaia). There are some very small '''green urban areas''' which count the most to the total green region. The industrial or commercial units sit in Siutghiol's proximity as well and as mentioned before, some of their waste is disposed in the lake with little to none consequences. As for the '''natural side''', there are a few inland marshes which don't cover a big part, a little area dedicated for pastures, the Danube-Black Sea Canal in the north and a transitional woodland-shrub area. Right before the northern entrance to the Constanța Municipality, there is a '''mineral extraction site''' which is still exploited to this day. The rest of the area is covered by the '''agriculture''' branch which extents to the nearby cities and it's a common sight in Dobrogea. The road network is not as developed as you would expect, but it is definitely present as the '''A2 Highway''' (also known as The Highway of the Sun) crosses the west side of the lake.

The '''forest''' zones are far gone as you can barely find any trees within the study area (there are a few between Ovidiu and Palazu Mare or in the green urban areas) and not because of the climate type or soil compositions, but because of high '''deforestation actions''' in the past decades. Some industrial units don't work anymore and there is a changing tendency to commercial units instead. The wild beaches that once were on the sandspit were replaced by the touristic resorts which is constantly expanding. The land and water use will definitely change in the near future as the urban areas extend in a worrying manner and the agriculture is slowly fading away. Authorities will most likely use every inch of the coastline if no action is being taken anytime soon. Despite its natural genesis, the Siutghiol Lake has definitely met high anthropic interventions as the time passed by and you can see its older days remains only in a few places now.

== Cultural and spatial typologies of water areas ==
With the formation of the Mamaia estuary, due to the closure of the Black Sea bay, along it, on one side and on the other, numerous constructions appeared. On the side with Lake Siutghiol, a series of '''hotel and restaurant units''' were built, as well as '''recreational areas'''. From the perspective of the natural environment, Siutghiol evolved at the same time as Lake Tăbăcăriei, contributing to its supply of water, through the canal that connects them. The presence of the lake favored the development of the tourist infrastructure, due to the landscape it offers, but it also influenced the urban configuration of the city, by building residential centers and by developing the street plot. Regarding the cultural part of the region, it is found only in the '''campus area''', through the presence of Ovidius University, and in the area of [https://en.wikipedia.org/wiki/Mamaia Mamaia Resort], on the lake side, these characteristics are missing, but are offset by those on the sea side, where there is a '''casino'''.

In general, water areas create attractive points at the level of a city, as they are the main agreement area for citizens. As an example for the city of Constanța, we are talking about Lake Siutghiol and Lake Tăbăcăriei. If we look at the water area as an essential resource for development, Lake Siutghiol has been an important area since the distant past, on the shores of which various buildings have been erected, both '''residential, commercial, recreational, cultural and sports areas'''. Lake Siutghiol plays an important role in the urban development of the city, as it offers the possibility to carry out activities for leisure and relaxation, such as '''fishing, walks around the lakes and boat trips'''. The increasing accentuation with built spaces, of the area between Siutghiol Lake and Mamaia Boulevard creates the idea that '''the place is not for people''', because the investors who did not take into account the demographic side of a city.

== Sacred spaces and heritage ==
The Black Sea coast has been occupied by many civilizations over the time (Greeks, Romans, Ottomans and so on) so there is no surprise that they left a '''generous cultural heritage''' behind them. There is no well preserved archaeological site around the Siutghiol Lake, however you can still find some Paleolithic settlements in [http://ran.cimec.ro/sel.asp?codran=60525.01 Mamaia Sat] and Ovidiu that are set to be exposed soon by the archaeologists. You can also find a [http://ran.cimec.ro/sel.asp?codran=60696.01 Roman-Byzantine fortifications] on the western side of the lake, on a small [https://en.wikipedia.org/wiki/Promontory promontory] of the [https://en.wikipedia.org/wiki/Ovidiu Ovidiu] city and another one in Palazu Mare. There are no sites on the Mamaia sand-belt discovered most likely because it is a relatively new geomorphological formation and there was no point in building settlements on vulnerable and exposed land.

The irrational tourism, lack of investments into national cultural heritage preservation and misguided excavation actions by unqualified staff lead to the sites being forgotten in the local touristic routes and little to no attention is given to them. Because the cultural heritage is '''unable to recover once damaged''', any rehabilitation action done by the archaeologists is '''highly restricted'''. The [https://en.wikipedia.org/wiki/Archaeological_tourism '''archaeo-tourism'''] (tourists who practice thematic cultural routes) is often overshadowed in Dobrogea by the other local sights such as the [https://en.wikipedia.org/wiki/Danube_Delta Danube Delta] and [https://en.wikipedia.org/wiki/M%C4%83cin_Mountains Măcin Mountains] in the north, or the resorts in the south. However, despite not living on the high profile, it emerges only when it's needed to and if the right effort is put into it, then it can serve as a great '''economic resource''' to the community.

== Visual appearance and landscape narrative ==
[https://fr.wikipedia.org/wiki/Miron_Costin Miron Costin] claims the existence of a lake in the counties near the [https://en.wikipedia.org/wiki/Dniester Dniester river], called either ''Owidowo, Vidovul, Ovidiului Lake, Lagoul Ovidouloui, Vidovo Lacus, Ovidovo Lacus'' or ''Vidovo Lake'' in different cartographical documents from various centuries. Many chroniclers, writers and poets have been writing about the Siutghiol Lake since the 16 th century. The lake was often mentioned in historic documents as well as travel guides and poems. Those who wrote about the lake often associated it with the name of the roman poet, Pūblius Ovidius Nāsō because, as the legend says, he was exiled by Emperor Augustus in 8 AD on a small island (link insula) located in Siutghiol Lake.

On a festive day, when the villagers were celebrating in their homes, a man sneaked into the village. He asked many people to be let to stay overnight but without success. Seeing that no one is welcoming him, he decided to head to the edge of the village. He found there a small house made of stone where an old woman lived. She, unlike her neighbors, was kind and let the stranger stay as long as he wished to. The old woman was worried as she did not have anything to feast the man with. The traveler told her to put some manure in the furnace and so she did. The woman was astonished when she opened the furnace door as she found there an enormous bread that would become whole again after each bite. The next day, as the traveler left, water came out of nowhere and the village sunk. Everything was gone. Only the stone house remained and a crystal-clear lake formed.

The water is the central focus of this area along with the flora and fauna that depends on it on a long term, like the local plants and animals do, as well as on short-term, like the migratory birds that nest in this area.

== Accessibility and usability ==
The main access routes to reach the Siutghiol Lake by car are the '''Ovidius University campus''' in the south, , the whole '''Mamaia and Aurel Vlaicu Boulevard''' – not to mention the open space sand barrier where the Mamaia Resort lies - plus secondary thoroughfares such as Ovidius University, Jade and Border Alley, as well as other unmarked roads or natural ones.
As mentioned before, the Siutghol Lake is accessible in certain areas such as the Mamaia Resort, or - on the southern shoreline - by '''Aqua Magic''', part of the area near the Ovidius University. But the accessibility can also refer to areas where the lake can be admired in all of its glory, with or without the built infrastructure to serve the tourists such as hotels or restaurants. In terms of spatial obstacles, the constructions in general prevent the development of other activities along the lake shore - a matter easily noticed on the eastern coast where the '''buildings density''' is higher than it should be. Also, the lake has certain areas in Mamaia where it is not organized at all and presents possible dangers to the local biodiversity because of the '''household wastes'''.

The area of the Siutghiol Lake is mainly used by the local '''investors''', who want to extend the resort as much as possible, in order to exploit the area economically. Of course, tourists are a common typology to be seen around the lake. Lately, this area has been used intensively for the development of '''mass tourism''', by building hotels, restaurants, parks and other touristic sights. Another purpose for which this area is used is for leisure, boat trips, water sports, and in addition to these, fishing also takes place, an activity practiced by both amateurs and professionals. The area of Lake Siutghiol, belonging to the resort of Mamaia is used to own the JT Watersports water park, and it’s open only during summertime, next to being located the only floating restaurant in Mamaia, which is under construction. On the Ovidiu Island not many things are going on, there is a little restaurant and a wharf for the tourists.

== Community Mapping ==
What is to be mapped here?
*'''Social groups''' from within the community, for example the youth, kids, students, parents, the retired etc. Typically, these groups have specific needs, which you can also make explicit on the map. These people might not be organized in any way, but they are usually present in the context you are observing
* '''Local stakeholder groups''': these groups are organized in one or the other way. They only exist within the community context you are observing. For example: the local community center, local churches, local interest groups, the landowners, small businesses and retailers
*'''External stakeholder groups''' are not necessarily present in the environment you are observing, but they may have strong stakes and interests. These can be local authorities, politicians, associations, care services etc.
* For each group, you may identify their '''needs, objectives, power and capacities'''
* You may also identify gaps and '''power conflicts'''
* Please try to redepict these elements in an integrated way and in relation to your water landscape. What is the relationship between these groups? Are they close or distanced from each other? Who is more powerful? Which voices are hardly heard? Do they have any shared concerns?

= Possible Futures =
For the risks map, we took into consideration '''five main problems''' that occur within our study area. The most negative part found here is the '''overpopulated shore''' of the lake on the eastern side where the Mamaia Resort is located, full of high buildings which are full with tourists during summertime. In the southern part there is the Constanta Municipality which also impacts the lake's ecosystem because of the '''huge amount of cars''' crossing the lake every day.
All this high population density leads to another problem in the area which is the '''household waste''' found at nearly every corner. A few volunteering institutes (one of them being the '''Ovidius University''' itself) have cleaned some of the areas, however the garbage always gathers overtime because of the lack of education. 
The '''industrial areas''' around the lake are also a top contributor for the pollution as there is little to none governmental action to ban the waste disposal from the factories in the water. Some other risky factors might include things like the possible '''landslides''' that might occur because of the common cliff structures and the areas exposed to '''floods''' which, so far, are not put in danger, however considering the climate change and the rise of the ocean level, this might be a problem that the locals might will face sooner than anticipated.

As for the future potential map, we took into consideration the implementation of '''green roofs''' on the Mamaia sand-belt since the buildings density is already high, a biomass power plant in the north which basically burns waste and makes eco-energy in the process, a '''marine lock''' also in the north for possible floods and a '''photovoltaic park''' between Ovidiu and Constanța which would supply both locations with solar energy for as much as it can provide, especially during summertime when the tourism is at its peak.
This diagram refers to the forces ('''driving forces''') which manifest a pressure above the living state of an natural system. This pressure result in an '''impact''' which is mostly bad and his main result is to destroy the natural resilience. The main driving forces which take place in this area are the political environment with his legislation, the process of energy consumption, the tourism, farming and the industry. This forces shapes the areal and forces it at some great pressure. The '''pressure domain''' , as you can see in the graph is formed by the '''uncontrolled expansion''' of the built space, '''poaching''', '''lack of green infrastructure''' and the '''exhaustion of the natural resources'''. These are a few examples, the most relevant and the most visible things you can discover with your own eyes in the surroundings of the Siutghiol Lake and in the city of Constanta. 

Regarding the state of the lake, first of all, Siutghiol is included in the category of '''Natura 2000 protected sites''', being a '''lagoon''', whose water is fresh. It has an alkaline pH, between 8 and 9, and in terms of phosphorus content, which has a tendency to increase, the lake tends to become '''eutrophic'''. It is known to have '''31 species''' '''of protected birds''' ,both nesting and migratory. The habitat types in the lake are mostly psammophilic and calciphilic. 

Human's activities always have an impact on nature and biodiversity because people change the place where they live as they please. The most important impacts resulting from the pressures are pollution, caused by the uncontrolled expansion of buildings and the lack of green infrastructure. Reduced biodiversity, the growing number of buildings has negative effects on the life of the species, but poaching is a determining factor, their amount of light is reduced and their habitats are destroyed. Increasing resource consumption is an important impact, as it reduces the natural environment and habitats of the species present. However, the big problem is exceeding the support capacity of the environment and decreasing the '''optimal''' standard of living, which influences both the environment and the population. 

In terms of '''solutions''', surveillance of the area with cameras and drones can solve the problem of poaching, reconversion programs of existing buildings in some that include green infrastructure, such as green roofs, can reduce the lack of clean infrastructure, but also reduce pollution in a small measure.
'''Green City''' - is a positive scenario for the lake`s neighborhood, which involves the use of solar panels, forest cords, green roofs and wind farms around the lake. It`s a good idea to develop the shores of the water in an eco style. 

'''Urbanization''' - this is a negative scenario, which involves a high urbanization, in particular on the east shore, in Mamaia and Năvodari. This constructions, extended irrational, will lead to a huge anthropogenic pressure on the fauna and flora. 

'''Invasive species''' - this has also a negative impact on the faunal & floral balance, and in this case, our water landscape will have big problems with the support of life. 

'''Drought'''-the lake dries up - If this happens, all species who live here, both in waters of the lake and on its shores will disappear. That can be the end of our water landscape and, after all, the desertification process will reach high levels in this area. 

'''Floods''' - a natural hazard, which happens time to time in all over the world, in some particular conditions. This scenario will lead to water pollution and also will cause serious damage to agriculture and settlements near the lake. 

'''Nuclear explosion''' - which is probably the worse case scenario for the entire region, including our lake. We all know what happened to Cernobîl, in 1986, where hundreds of humans and also animals died after the exposure t the radiation, and this process can continue many years after the explosion moment.
