Model Regions

All ReWaM projects address the diverse challenges of regional water resources management in model regions. The model regions and study sites are located throughout the entire Federal Republic of Germany. In total, the joint projects are studying watercourses, lakes, reservoirs and groundwater bodies in 13 federal states. This will allow the transfer of the research findings not only to other regions in Germany, but also to other European countries.

BOOT-Monitoring The joint project will study two model regions: The ‚Freiberger Mulde‘ serves as a model for rivers in low mountain ranges. The river Tollense is a model for rivers in lowlands, its lower reaches have been substantially modified by human activity. There are also plans to study other model regions within the framework of a cooperation with the joint project RiverView.

 

CYAQUATA In Germany, reservoirs supply a large percentage of drinking water. Around 40 percent of the drinking water in the federal state of Saxony comes from reservoirs. Four reservoirs in Saxony (Saidenbach, Neunzehnhain, Gottleuba, Quitzdorf) of different trophic level and use were chosen as model regions.

 

FLUSSHYGIENE The project will study seven rivers which are divided into four model regions and which are very different with regard to river type and -structure, water quality, and types of use:

  • The Spree-Havel river system in the city of Berlin
  • The Isar and Ilz rivers in the state of Bavaria
  • The Rhine and Mosel rivers near the city of Koblenz in the state of Rhineland-Palatinate
  • The Ruhr river in the state of North Rhine-Westphalia

 

GroundCare The project will study seven modell regions with different characteristics:

  • City of Augsburg, Lechaue waterworks
  • City of Berlin, waterworks of the Berlin water utilities
  • Northern Ruhr district and western Münster region, Halterner Sande
  • City of Würzburg, waterworks Mergentheimer Straße
  • City of Hanover, waterworks Fuhrberger Feld
  • City of Dresden, contaminated site Coschütz/Gittersee
  • Stürmlinger sand pits near the city of Karlsruhe, landfill site

 

HyMoBioStrategie Research will take place on the northern shore of Upper Lake Constance at six selected study areas with different characteristics. Geographically, Lake Constance is situated in the foothills of the Alps and is fed mainly by the Alpine Rhine River.

 

In_StröHmunG The joint project will study four model regions with different characteristics:

  • Mortelbach and Eulitzbach (cities of Waldheim and Roßwein, municipality of Kriebstein)
  • Mutzschener Wasser and Launzige (cities of Grimma, Trebsen and Colditz)
  • Zwönitz river near Chemnitz (district of Einsiedel)
  • Aller river near Celle

 

KOGGE The chosen model region of Rostock is distinctive for cities of the northern German lowlands. Characterised by its low relief and marked by long-time anthropogenic influences, the city of Rostock comprises various types of water bodies such as estuaries and drainage ditches and additional standing waters and wetlands. The manifold small creeks throughout the city area provide vital ecosystem services while at the same time being exposed to anthropogenic stress. Resulting from its flat morphology there exist intensive interactions between groundwater, surface waters, the drainage system and further urban infrastructures.

 

MUTReWa The joint project will study two model regions:

  • Catchment area of the Mühlbachin southern Baden-Wurttemberg, southwest of thecity of Freiburg: Themodel region is representative of intensive farmingwithspecial crops(vineyards) and a highly dominantmonoculture(corn)
  • Lowland catchment area Kielstau southeast of Flensburg: Characterised by drainages and lateral drains from intensively farmed areas (rape, cereals, corn)

 

NiddaMan With a length of 89.7 kilometres and a catchment area of 1,942 km2, the Nidda is one of the key rivers in the German state of Hesse. The Nidda is characterised by agricultural and industrial use, inadequate water structures, high pollution, settlement activity, a poor ecological status, and flood risk in the catchment area.

 

RESI The joint project will study five model regions with different characteristics:

  • Bavarian Danube between Neuburg and Deggendorf
  • Upper Rhine river between Basle and Mainz
  • Middle Elbe river between Torgau and Magdeburg
  • Havel-Spree region
  • Wupper catchment

 

PhosWaM

The studies focus on the catchment area of the river Warnow, the river Unterwarnow and the adjacent coastal waters of the Baltic Sea. At 3,324 km², the Warnow and Unterwarnow are the second largest German catchment area that drains into the Baltic Sea. The region is mainly agricultural, and its hydrologic balance has been strongly altered by anthropogenic influences.

 

RiverView

Selected rivers of the Eifel-Rur Water Association (Roer, Inde, Wurm) and the rivers of the Emschergenossenschaft / Lippeverband (Lippe, Emscher and their tributaries) in North Rhine-Westphalia will be monitored by boat. There are also plans to monitor other model regions by boat in the context of a collaboration with the joint project BOOT-Monitoring.

 

SEEZEICHEN With its more than 500 square kilometres, Lake Constance is the second largest alpine lake and, after Lake Geneva and Lake Balaton, the third largest inland lake in Central Europe.

 

StucK  Two model regions near the Hamburg metropolitan area will be studied. One of them is the Dove-Elbe catchment, whose inland drainage is directly impacted by the external water levels of the tidal Elbe. The second model region is the Kollau catchment, where the tidal Elbe has only little impact.

 

 WaSiG  The districts Kronsberg in Hanover and Vauban in Freiburg, which are well known for their exemplary character in the field of sustainable urban development, represent a very suitable platform for implementation and are accompanied by quarters in Münster.
