Die gekoppelte Simulation der 2D-Oberflachenwasser- und 3D-Grundwasserstromung im Rahmen eines Expertensystems zur Modellierung der hydrodynamischen Wechselwirkungen

摘要

The European water framework directive provides a framework for integral protection of surface water, costal water, transitional water and groundwater using the river basin as the geographical and administrative basis for the water management. New practical and technical questions arise from the implementation of the framework which needs new holistic approaches and the linkage of different fields of research and practical work like biology, ecology, hydrology, hydraulics, land and river management. Based on the claim for a "good ecological state" of the European river system an expert system was created with the aim to generate abiotic indicators of landscape development with a high resolution in time and space. One important part of this expert system is a component to simulate the interaction between surface and groundwater flow using a two dimensional surface flow model and a three dimensional groundwater flow model. The scheme used to combine these two models is described and first results for the application of the expert system to two model areas are shown and discussed.
