Analyse eines urbanen Gewässereinzugsgebietes als Planungsgrundlage nachhaltiger Wasserbewirtschaftung am Beispiel der Wuhle im Raum Berlin

Abstract (Summary)
The exact knowledge of the water balance is the basis of the water supply and distribution within a catchment area. In an urban area the boundary conditions of the civil engineering like the sewer system or the hydraulic engineering plays an important role. To quantify the water balance a conceptual approach was developed which takes the current conditions and their interdependence into consideration. The impact of changing conditions on the water balance can also be simulated. As investigation area the catchment of the Wuhle River was chosen because it includes all relevant aspects of water management. The Wuhle River has its source on the ground moraine of the Barnim plateau directly at the city boundary in Ahrensfelde and reaches the Spree in the quarter Köpenick after about 15.7 km. This method uses a differentiated calculation by area to determine the total outflow of rainfall minus evaporization. It also determines the submontane and aboveground distribution. For verification purposes detailed hydraulic investigations were carried out at the Wuhle. With the production rate of the waterworks the groundwater balance was then calculated. As a result the amount of bank filtrate of the total groundwater withdrawal was determined in a hydro geological way. Using the simulation software FEFLOW© a numeric model of the flow pattern was created to simulate the influence on the water balance and the groundwater. The displayed subterranean catchment area of the water work Wuhlheide was based on the water table contours which were interpolated from a fixed date measurement of the groundwater heads. By comparing the simulated groundwater heads and the water levels from the fixed date measurement an additional verification of the water balance was realised.
