Rationale
The Neckar is included and fit into human usages in the area, where its passing though Stuttgart and it divides Stuttgart Bad Cannstatt from the inner city. Through that the study area is a point of connectivity and mobility in each manner. In history the people in charge of of the urban water site switched and now multiple stakeholders are somehow connected to that. For the inhabitants the study area is just a point of crossing and moving, while totally disconnected to river. Moreover, in the future there will be a shift of usages of railways, new ones are under construction right now, additionally the contracts for electric power generation with the big companies will end 2034. These shifts could be used to re-shape and re-connected the people to the river.
Location and scope

Water as a natural system
Geomorphology, typologies and dynamics of water areas
The Neckar flows from its origin near Schwenningen to Mannheim, where it leads into the Rhein. Er überbrückt damit eine Distanz von 371 km und eine Höhendifferenz von 621 m.
The development of the catchment area started already in the Cretaceous period with the cave in of the Oberrheingraben and the beginning rise of the Swabian Alb. Consequently, the catchment areas of Danube and the earlier river Rhein changed. The Neckar receives its water now from 13.600 sqkm catchment area. Important is the perception minus evaporation in that area. The water level therefore depends highly on weather, so seasonal and shortly changes are visible. The average yearly perception in the catchment area are between 600mm to 800mm.
Water as a living space
In Stuttgart's urban environment and due to the expansion of the federal waterway, the Neckar has been increasingly forced into a built corset in recent centuries. Nature conservation and environmental protection, as well as biodiversity, hardly played a role. North of Stuttgart, between Aldingen and Stuttgart-Mühlhausen, lies the nature reserve "Oeffinger Scillawald". It is named after the large occurrence of blue star and consists of a deciduous forest that used to be frequently found along the Neckar. This is the only nature reserve along the Neckar near Stuttgart. Up to Plochingen, the end point of the waterway, the river and the riverbank are industrially used and deformed.
In addition to the Neckar, there are 16 other streams in the Stuttgart area. Their total flow length is approx. 150 kilometres, the longest stream being the Feuerbach with a length of 11.5 km. There are also other standing waters in the Stuttgart area. The largest lake is the Max-Eyth-See with an area of 17.3 hectares. (State Capital Stuttgart Civil Engineering Office (2020): Portrait of Stuttgart's water bodies)
The water quality of the Neckar suffered and still suffers from the various industrial uses and structural changes. The 27 barrages slow down the flow, which can lead to a lack of oxygen as there is no longer any turbulence. The critical mark is below 4mg oxygen/litre (LUBW; https://www.lubw.baden-wuerttemberg.de/wasser/chemischer_zustand).
Likewise, sewage treatment plants discharge their treated wastewater into the Neckar, but polluted water is still fed into the river. Swimming in the Neckar is therefore not recommended.
Furthermore, rising temperatures affect the water temperature and thus the ecological condition of the water body. The critical mark of 28° degrees should not be exceeded. However, the water of the Neckar is used as cooling water by the industries on its banks. If the water temperature rises, the power plants must reduce their output in order to protect the "Neckar" habitat. (Regierungspräsidium Stuttgart (27.08.2018): Hohe Temperaturen im Neckar: Regierungspräsidium erteilt Ausnahmeerlaubnisse für drei Kraftwerke der EnBW, Pressemitteilung). The following graphs show how precipitation in the Stuttgart area affects the water temperature and oxygen content of the Neckar with a slight delay. The increased inflow of rainwater lowers the temperature and the increased flow velocity allows more oxygen to enter. The fourth graph shows the rising water temperatures over the course of the year.
The graphs show the daily mean values of oxygen content and water temperature of the Neckar for the last 6 weeks, counting backwards from 29.04.2022. Source: https://www.lubw.baden-wuerttemberg.de/wasser/fliessgewaesserdaten?id=2872#diagramm

Within the framework of the Baden-Württemberg Surface Water Ordinance, the Neckar in the urban area of Stuttgart is assigned to the fish community of the epipotamal. This fish community includes, for example, eel, bitterling, flounder, pike, rudd, tench and zander. The species-specific preferred temperatures for this fish community are up to 25° degrees in summer and up to 10° degrees in winter. (LAZBW(2020): Assignment of fish communities and resulting temperature requirements according to the Surface Water Ordinance in Baden-Württemberg)

Visual appearance and landscape narrative
The König-Karls-Brücke from 1997.
I can't be in the river or on the river - but metall trash can?
Typical image from the bridge - Industrie and other opportunities to cross the river. Everything is straight and calm and it seems to not move at all - is the river alive?

The river also played a role in poetry.
Friedrich Hölderlin a well-known German writer and poet lived from 1770-1843 and wrote a famous poem about the Neckar.
Der Neckar
(written around 1800-1806)
In deinen Tälern wachte mein Herz mir auf
Zum Leben, deine Wellen umspielten mich,
Und all der holden Hügel, die dich
Wanderer! kennen, ist keiner fremd mir.
Auf ihren Gipfeln löste des Himmels Luft
Mir oft der Knechtschaft Schmerzen; und aus dem Tal,
Wie Leben aus dem Freudebecher,
Glänzte die bläuliche Silberwelle.
Der Berge Quellen eilten hinab zu dir,
Mit ihnen auch mein Herz und du nahmst uns mit,
Zum stillerhabnen Rhein, zu seinen
Städten hinunter und lustgen Inseln.
Noch dünkt die Welt mir schön, und das Aug entflieht
Verlangend nach den Reizen der Erde mir,
Zum goldenen Paktol, zu Smyrnas
Ufer, zu Ilions Wald. Auch möcht ich
Bei Sunium oft landen, den stummen Pfad
Nach deinen Säulen fragen, Olympion!
Noch eh der Sturmwind und das Alter
Hin in den Schutt der Athenertempel
Und ihrer Gottesbilder auch dich begräbt,
Denn lang schon einsam stehst du, o Stolz der Welt,
Die nicht mehr ist. Und o ihr schönen
Inseln Ioniens! wo die Meerluft
Die heißen Ufer kühlt und den Lorbeerwald
Durchsäuselt, wenn die Sonne den Weinstock wärmt,
Ach! wo ein goldner Herbst dem armen
Volk in Gesänge die Seufzer wandelt,
Wenn sein Granatbaum reift, wenn aus grüner Nacht
Die Pomeranze blinkt, und der Mastixbaum
Von Harze träuft und Pauk und Cymbel
Zum labyrinthischen Tanze klingen.
Zu euch, ihr Inseln! bringt mich vielleicht, zu euch
Mein Schutzgott einst; doch weicht mir aus treuem Sinn
Auch da mein Neckar nicht mit seinen
Lieblichen Wiesen und Uferweiden.

- Who is using the spaces and how?
Accesible? Running against metal fencing
How should I touch the water?

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?
