Description
In order to analyze the impact on the groundwater levels due to relocating a dam, which currently is located along the Danube river, a groundwater model is developed.
The additional retention area can be used as a preventive and decentralised flood retention.
Based on given geological, hydro-geological, and topographical data combined with initiated groundwater measurements, a three-dimensional transient groundwater model is developed.
The model includes the entire investigation domain, the boundary conditions, a 3-dimensional digital surface model and the model parameters such as conductivity and porosity.
The model parameters have been calibrated.
The infiltration of surface water through the different im- permeable surface layers into the soil is modelled by a leakage approach which also has been calibrated.
