Water as a natural system
Geomorphology, typologies and dynamics of water areas
- Describe the water areas of your area in the contxt of the wider water system
The Tăbăcărie Lake is a natural lake located in the northern part of Constanța and belongs to the Coastal Hydrographic Basin of Black Sea, the lake has an approximately rectangular shape with low shoresand and the banks being covered with vegetation mostly by reed.
Existing water bodies in the area:
1. Tăbăcărie Lake, which has an area of 99 hectares and an average depth of the lake being 1.5m, The lake being located in an elongated depression area helped to creation of the lake by blocking a previously existing river
2. Siutghiol Lake, which has an area of 1900 hectares and the maximum depth of the lake being 17m, The lake is separated from the sea by a coastal cordon. Siutghiol communicates through one artificial channel to Tăbăcărie Lake that is connected with the Black Sea through another artificial channel.
- How does water appear in the landscape of your living lab? What types of water areas are common?
There are two types of water bodies: lakes and artificial channels. The lakes are naturally formed with fresh water, both lakes with an approximately rectangular shape communicating with each other through artificial channels: Siutghiol-Tăbăcărie Canal and Tăbăcărie-Black Sea Canal.
The evolution of Siutghiol and Tăbăcărie lakes is the result of a combination between natural and anthropogenic factors, the climatic factors having a decisive role in the genesis of both lakes.
From a genetic point of view, Lake Tăbăcărie is included in the category of fluvio-marine estuaries. From a sedimentological point of view, the area of Lake Tăbăcărie is related to the evolution of Lake Siutghiol, located to the north, but also to the processes of erosion of the banks of the basin in which it was formed. The shores of the lake are completely rectified and consolidated. The western shore rises to an altitude of 6-7 m and to the eastern and south these elevations are lower, being between 2-4 m. In its northern part, the coast is very low, 1-2 m.
- Please identify the water bodies' catchment areas, tributaries and floodplains
Lake Tăbăcărie belongs to the Coastal Hydrographic Basin, a basin that has an area of about 3958 km2. Along with Tăbăcărie, from the Hydrographic Basin, there are also the lakes Tașaul, Hagieni, Limanu, Techirghiol etc.
The lake is supplied with fresh water from the Siutghiol Liman. It is known that at the bottom of the estuary there are a series of fresh water springs.
- Which dynamics do these water areas have?
More than 100 years ago, in the area of Lake Tăbăcărie there were two leather factories, where many locals worked and where skins and furs were processed with a mixture of substances. The book (Constanţa and its surroundings,1960) mentions that: “The lake takes its name from the local industry “Tăbăcăria Mică”, found in these places in 1896. Those who worked in the tannery were mostly women and young people, and they were paid reduced wages. Two years later, "Tăbăcăria mică" ceased its activity. In 1880, on the place occupied today by the building of the maritime research station, it resumed its activity with the name "Tăbăcăria Mare".
Lake Tăbăcărie was surrounded in the last century by the city of Constanța, it directly underwent human interventions, such as dredging, earthworks and heavy pollution. The sediments on the surface of the lake are generally fine-grained: clay and mud, with sands that appear only on the dredged bottoms. Analysis of the chemical composition of the sediment surface revealed the presence of large amounts of certain heavy metals, in particular: Zn, Ba, Cu and Pb, dispersed mainly near the points of discharge of rainwater pipes. At the level of 1993 in Tăbăcărie Lake, both rainwater and urban wastewater (domestic and industrial), which led to the degradation of the aquatic environment. In the years 1978-1979 the basins of the lake were dredged, and the shore arranged with pedestrian alleys.
Following the dredging works, the highest depths (maximum 3.70 m) were highlighted in the northern part of the lake, where the topography of its bottom has relatively steep slopes due to dredging operations. Initially, the dredging was done evenly throughout the lake, but the supply of rainwater and wastewater, with a large load of solid suspensions, led to the partial clogging of the southern sector. Here are located the most numerous sources of discharge of solid material (sand, gravel), as well as decomposing organic material.
- Have there been any flood events in the past?
The possibility of floods is drastically reduced by the shores that were rectified, strengthened and arranged between 1978-1979 by these anthropogenic changes. The shore was changed by 125 cm above sea level, so that these flood possibilities are almost impossible at present with the shores of the lake "corrected" and with a shape closest to that of the circle.
Between the Siutghiol, Tăbăcărie and Black Sea, artificial canals were built so that the excess water was discharged into the sea by a dam located in the “Pescărie” area (Pescărie area is the north east canal that connects Tăbăcărie Lake to Black Sea).

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?
