Using FEFLOW and MIKE HYDRO River, we were able to describe the water level development of the lake. This was done with detailed information about the inflow into the lake (groundwater inflow, surface water inflow, as well as rainfall and evaporation at the surface).
In addition to the inflow into the lake, it was important to obtain detailed information about the long-term water needs as well as the water availability of the Spree river. We used a water management and allocation tool for the long-term management analyses of the pit lake. In addition, we also used MIKE Hydro River for the 1D hydrodynamic analysis of maximum flows and the planned diversions in the Spree as well as its tributaries.
