Analyzing the Effects of Groundwater Influenced Flooding of a Large Abandoned Mining Area in Eastern Germany
Since the end of the 19th century, parts of Eastern Germany have been characterized by large industrial zones, producing lignite and electricity.Some of the industrial activities are planned to be phased out by 2015 and a number of old pits have already been transformed and integrated in a large regionally unique lake district.One of the lakes to be developed is the Cottbuser Ostsee to the East of the city of Cottbus (mining pit Cottbus-Nord).DHI-WASY was contracted to analyze the flooding process of this lake.The flooding is strongly groundwater influenced and is modeled by a 3D groundwater FEFLOW model.The characteristics of the lake (water level dependent volume and area) are represented by a separate plug-in called IfmLake.With the modeling it was possible to develop an optimal strategy for the flooding (duration and water availability) as well as to analyze the effects of the flooding on the surroundings of the lake, especially groundwater depth in sensitive economic or ecological zones.Furthermore, the analysis of the flooding process was reproduced using the plug-in IfmMIKE11, which couples FEFLOW with the surface water model MIKE11.By integrating this surface water model additional features and analyzing possibilities could be used.Results of this comparison, advantages of this method and potential fields of application are highlighted in this study.
