Rationale

• Why do you think this case is relevant? What is your hypothesis considering the landscape challenges?

The main parts of the city of Nuertingen extend along the fast-flowing river Neckar, such as the center of this city, Neckarhousen, Oberensingen, and Zizishausen. Proximity to the freshwater is an important factor for the life of the citizens and for the animals. However, lack of accessibility, regular air, and water pollution have an effect on the sustainable future of this city, as well as flood events, which are the biggest challenges of the Neckar River.

Water as a natural system

Geomorphology, typologies and dynamics of water areas

• Describe the water areas of your area in the context of the wider water system

Neckar is a major tributary of the Rhine River at Mannheim. Rising at the Black forest and flow through a steep valley in the Odenwald Mountain and also passes through Tubingen, Nurtingen, Esslingen, Stuttgart, and Heidelberg.

Neckar valley water system can be classified between three segments:

In the Northern, from Kirchheim to Stuttgart, the upper course closest to the source of River Rhine. Narrow and steep gradient with vineyards and highly affected by vertical erosion and striking rock formation but only has 6-meter height waterfall at DeisslingenLauffen, where rapids were occasionally seen at Lauffen at Neckar when erosion occurs and gorge found in the Odenwald the district of Neckargerach at Neckar.

In the Central, from Stuttgart to Plochingen, the middle course is characterized by Urban structure, cultural and landscape diversity where a river starts to slow down, get wider, and travels in a winding loop having a lot of lateral erosion, transportation, and deposition. Floodplains meander, oxbow was founded in the history of River Neckar. Neckar’s oxbow was established when the Neckar loops were penetrated in the year 1933-1934 where expansion and canal were created.

In the Southern, from Plochingen to Neckartenzlingen, the lower course is the final segment where the river gradient is at its gentlest, as the river approaches the sea, it has a wider smooth channel and moves at its slowest speed where large flood plains, deltas, and estuaries levees found. Here ship no longer can pass through, Orchards and lands of wood were also found with some residential and industrial areas

• How does water appear in the landscape of your living lab? What types of water areas are common?

The Neckar is 362 kilometers longer (225 mi), the Neckar valley is cut in the deepest by over 400 meters through the mountains Water appears in many forms depending on the natural geomorphology, typologies, and dynamics of its flow. In a wider context watershed, drainage basin, catchment area or the cultural or built environment by humans is also responsible for its appearance, the River, Lakes, Ocean, Sea, Tributaries, Streams, Puddle, Pond, Canals and Floodplains are the types of water areas that are common in our Living Labs

• Please identify the water bodies' catchment areas, tributaries, and floodplains

Catchment: The River Neckar catchment area is 13,900 km2 (5,378 sq mi) is located in the southwest part of Germany and is a tributary of the River Rhine valley. Tributaries Eschach, Prim, Schlichem, Glatt, Eyach, Starzel, Steinlach, Ammer, Echaz, Erms, Aich, Lauter, Fils, Korsch, Rems, Murr, Enz, Zaber, Schozach, Lein, Sulm, Kocher, Jagst, Elz, Ltter, Laxbach, Steinach, Elsenz.

Floodplains: Tributaries of river Neckar, Danube, Rhine, the Seine at the German state of Bavaria, Hessen, Rhine-Palatinate, Baden-Wurttemberg and North Rhine-Westphalia were affected floodplains

• Which dynamics do these water areas have?

The Dynamic equilibrium of the River Neckar subjected to the topography of the middle-Neckar River region is surrounded by two mountains, the western black forest, and the south-east Swabian Alb, the river valley of Neckar at someplace in region, carved in the gently rolling hilly land and opens up into the vast plains. The Neckar sized 14000 km2, covering 40% of the total area of Baden-Württemberg, An area where about half of the population of the state live, which is situated primarily on the lee-side of the Vosges mountain. Overlapping the 200 year ago map we can observe that the river flow has been artificially channelized and sifted from its original position due to urbanization and human Intervention. The water flow is faster because channels are provided long and straightforward.

• Have there been any flood events in the past?

Yes, there have been many events in the past, the extreme flood events in central Europe were in the last two decades. • The flood events along the River Elbe in 2002. • The Flood after several days of heavy rainfall in June 2016. • Several flood events happened in 1993 on Neckar catchment.

Water as a living space

• Which habitats can be found in and along the water areas of your area?

Formation of habitats on the territory of the city Nurtungen has resulted to a combination of factors such as history, climate, geographical location, flora, and fauna of surrounding territories. The morphology of the territory also has a strong impact on the way of forming habitats. The city lies on the river Neckar, a mountain fast-flowing river, as well as a hydrographic network is represented by streams and small freshwater lakes. Leading development the city of Nuertingen, recapturing large areas of land, due to this, complex areas with alternating natural vegetation, farmlands, and urban territories are formed. Classification of habitats that can be found along and in the water of the river Neckar: Wetlands – marshy area, banks of the river, floodplain; Freshwater – riverine, streams, lakes; Urban – recreation, residential areas, gardening, and landscape design; Forest – old and young forests; Farmlands – pasture and orchards; Grassland – meadows, and slopes;

• How is the water quality in your water areas?

The Neckar in the territory of the Nurtingen runs through 3 dikes that slow down the river’s flow. In some locations can be found the dense settlement, especially along streams, and sewage treatment plants. As a result, a high nutrient proportion can be recorded, which leads to the significant development of algae during the summertime. The lack of oxygen due to the degradation of this organic material can be dangerous for many wetland and freshwater species. The warning level of continuously recorded oxygen by the power station is below 4 mg per liters. The level of pH of river water is also a very important parameter – the measure of hydrogen ion concentration. Low pH can be dangerous to immature fish and insects, while the high level of pH is also harmful to most organisms. The most optimal pH level which is considered for life – 7,4. The level with indicator 8.0 can be sufficient for most river species, but clams and snails usually prefer the higher level of pH. According to the last measurements the pH value in the river Neckar in the territory of the Nuertingen – 8,3.

• Which areas are still natural, which are urbanised/artificial?

The structure of the river and streams bodies is a very significant parameter, which contains bed and bank structures, course development, transverse and longitudinal profiles and watercourse environment. This parameter must be recorded because of two important reasons: - habitats should be available for well-being in and around the river; - flora should be naturally occurring in and along the river and streams; Baden-Württemberg water structure map shows that structure which was considerably changed and significantly changed with the largest share of the total assessments. There are about 40% of the river structure in an unchanged, slightly changed, and moderately changed condition. The results of structural completely changed class are composed of the waters that as a result of the individual parameters piped sections, this corresponds to approximately 20% of the total rated.

• Are the rivers permeable for fish or blocked by artificial elements?(approx 200 signs)

Since the Neckar river in the territory of the Nurtingen flows through 3 dikes it can block migration of fishes because these dikes have electro station and turbines, that dangerous for fishes’ lives. However, when analyzing and observing the river Neckar some artificial structures were sighted, next to the dikes, which provide an opportunity for free movement of fishes. These structures represented a new way for the fish migration separate from river flow towards to turbine. All calculations were done by specialists, according to the speeds of the river’s flow and observing the fish migration. These lots for the movement have stepped construction that allows fishes to have a rest after the long migration. In conclusion, the river Neckar has serious artificial elements that can block the movement of fishes, but some good solutions can be found along the river, so this part of the river is permeable for fish at this moment.

Water and People

Accessibility and usability

• Where are your water areas accessible, and where not? How strong are spatial obstacles preventing access?

According to survey analysis, only a small part of the river Neckar in the territory of the city Nuertingen is accessible for people – a cycling and walking path from the center to the sports area on the southern part of the river and a small area on the northern part of the riverbank between two pedestrian bridges. Other parts have serious problems with access to the river, especially Neckarhausen, which is separated from the river by the main and noisy Neckarstrasse road. Also, the residential area along the Muhlstrasse has constructions and “jungle” river banks that prevent people from visiting river Neckar.

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?
