Water as a natural system
Geomorphology, typologies and dynamics of water areas
Emajõgi, or the “mother river”, is the second largest river in Estonia. It is a fully navigable river, approximately 100km long that connects Lake Võrtsjärv to Lake Peipus. It is a relatively flat landscape, as from source to river mouth there is only an elevation difference of approximately 3,5m. The Emajõgi’s catchment area is around 9740km2 and represents approximately 60% of Lake Peipus’ total catchment area and 22% of Estonia’s territory. The Emajõgi has 12 tributaries: Pedja, Laeva, Amme, Koosa, Kavilda, Elva, Ilmatsalu, Porijõgi, Mudajõgi, Luutsna, Ahja and Agali.
The Emajõgi was the birthplace of Estonia’s second biggest city Tartu, first mentioned in written text in 1030. Tartu opened its first hydrometry station named “Tartu (Kvissentali)” in 1867, not an hazardous date, indeed it was also the date of the most important flooding event of Emajogi!
Generally, water in the Emajõgi river fluctuates up to 250 cm and flows rather slowly around 57,9m3/s.
After long winters, snow melts and generates a vast amount of water. This periodic phenomenon can produce floods. It happened quite a lot of time that water rises was approximately around 300 cm (1899,1923,1999,2005,2008, 2009) and caused temporary problems. In 1867, 2010 and 2011 rising waters were 373 (most extreme one’s), 330 and 315 cm. In our case: an urban context flooding period has direct consequences on urban planning surrounding Emajõgi’s dock.
The last important flood event was in 2010, some streets were closed and traffic has been restricted: "The pumping of water, the closure of ditches and other measures taken to prevent flooding have helped to stabilize the situation. Yesterday, the men of the rescue center and the Defense League closed a drainage ditch with a hundred sandbags in Tähtvere Sports Park in order to prevent the increase of the flood area in Supilinn," said Rein Haak, Head of the Urban Economy Department.
In some natural part of the river, flooding constituted a part of the landscape: meadows, bog. However, with climate change, urban sprawl and water management due to the city plan, flooding will increase and at some point constitute a risk for people who are currently living near to the river. To anticipate it, Estonian Government produces assessments and maps showing different futuristics scenarios of flooding (10,50, 100,1000 years).
Besides the Emajõgi, this Living Lab’s study area includes two other significant water bodies, Anne Kanal (9,5ha) and Väike-Anne Kanal (5,5ha). They are both located on the left bank of the Emajõgi in Annelinn, a predominantly Russian neighborhood in Tartu. These canals were excavated during the construction of Annelinn from 1965 to 1971 and intended to be one full lenght rowing canal. The construction of the Sõpruse bridge in 1977, over the original canal, and the need to fill its foundation with soil due to engineering constraints, eventually separated the canal into the two canals we know today.

Water as a living space
- Which habitats can be found in and along the water areas of your area?
Mostly the Habitats are fishes, birds, insects, flowers etc, that are found near our Study area, Mostly species are protected.
- How is the water quality in your water areas?
Tartu city drinking water is providing mostly by ground water sources and regarding to that, there are 111 bore wells most of which are divided between those ten water intakes located in Tartu [1]. From those the most important are Meltsikivi, Anne and Ropka water intakes. in addition to the bore wells of the public water supply of Tartu city, there are estimated to be over one hundred bore wells located on private registered immovables in the administrative territory of the city. Water in the uppermost part of the Quaternary aquifer is about half of the water consumed as drinking water in Tartu, and there is generally no need to further process it. Water in the Quaternary aquifer belongs to the first quality class. However, groundwater from deeper aquifers needs to be purified before use as drinking water due to the naturally higher content of some substances. Water in aquifers of Middle Devonian and Early-Middle Devonian-Silurian belong in the second quality class due to their high iron content and bore wells water of Ordovician-Cambrian in the third quality class due to their chloride content. All water of Anne water intake is led through the Anne water treatment plant and the water of Ropka water intake through the Sepa water treatment plant. There, the water from the Middle Devonian and Early-Middle Devonian-Silurian aquifers is purified of excess iron by aerating the raw water. Groundwater from the Ordovician-Cambrian aquifer, which is rich in chlorides, is not pumped directly into the water supply network but mixed with the Middle Devonian and Early-Middle Devonian-Silurian water [2].
Along downstream area from Riia old bridge to Sopruse pst bridge there are four ground water sources. They are quintenary well bores which three of them are Silurian-Ordovician (no need of purifying) and an Ordovician-Cambrian well bores which is rich in Chlorides (needs to be processed). On the other hand, The Bathing water Quality of the EmaJogi is Excellent but the quality of Anna Canal is Sufficient for bathing. Overall the water quality of Emajogi is good, near the bank of EmaJogi and Anna Canal there are drinking water bore wells that show the quality of water was excellent for drinking purposes
- Which areas are still natural, which are urbanized/artificial?
Generally, west side of Emajogi river from old bridge up to Sobra is urbanized/industrial and east part of it From Anne Canal until studying border is natural. Although, east part has constructed drainage fields and Anne Canal as artificial lake, still these areas are natural except minor changes as they mentioned. Significant urbanized/industrial areas are Old factory on west part and Anne Canal (constructed during soviet period for Olympic games) on the east part. Adding to that, on the upper part (from Kaarslid bridge) to south direction, there are more modern looking and urbanized constructions on west part rather than east part which is mostly green infrastructure.
- Are the rivers permeable for fish or blocked by artificial elements?(approx 200 signs)
As there is no barrage, Dam or any other structure, so that’s why fishes can easily pass and the river is permeable for fish

The bridges that stitch Tartu together have also been central motifs. Artists have also registered the development of Annelinn, and the subsequent creation of Anne kanal.
Lydia Koidula (1843-1886), esteemed Estonian poet, entitled her 1867 collection of poems “Emajõe ööbik” (The Nightingale of the Emajõgi River), which expressed budding national sentiments at a time Estonia was part of the Russian Empire:
O, Emajõgi – I see again
Your good smelling banks!
[---]
You holy Estonian river!
How you inspire my thoughts!
O, Emajõgi, where Vanemuine's language
Still flourishes,
Where we can still hear
His song and zither;
Where the young still remember
The words and deeds of Kalev
And recall the glory
Of old times
Where tall pillars stand
On his grave
And give spiritual light
To my Estonia.
(Koidula 1969: 77)

You have to stand about in the middle of the meadow, a few dozen meters away from the bridge, facing the bridge. On the left rises Karlova, drowned in greenery (unless winter or autumn), on the right rises Annelinn as a yellow stone wall, in the foreground the shopping center of Eden, reminiscent of the deserted cardboard city of Las Vegas from afar, as Berk Vaher once observed.

Water and People
Accessibility and usability
Generally, eastern part of Emajogi is more accessible in contrast with western part. Accessibility can be divided into major categories for pedestrians and vehicles. To be precise, there are five ports located at western part of river as Turusadam, Vaike-Turu Sadam, Joe Paadisadam, Karlova Paadisadam and Rebase Paadisadam which have direct access to water but they are limited as they are only usable for people with authorizations. Based on provided illustration, places with direct access are eastern river shoreline starting from Narva bridge down to end of living lab zone (Idaringtee bridge). Simultaneously, western part has various accessibility obstacles but still those is becoming faded mostly after “Rebase Paadisdam” port. Nevertheless, accessibility quality on easter part is mostly suitable and convenient for pedestrians rather than vehicles. Regarding strengths of spatial obstacles about water accessibility, reasons are various as important ones are private zones and Tartu city embankments. Private sections are commonly dwellings and industrial which preventing people from having direct access to river. Although this problem is negligible on eastern part and even embankments are not a draw back. Last spatial obstacle which contains wide range of eastern shoreline is natural conservation protected site which illustrated on map. Accessibility quality in this area is possible but not convenient even for pedestrians.

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?
