The reclamation of abondend open-cast mines in the region south of Leipzig raises many scientific questions. This research project focus on the simulation of groundwater recharge. The knowledge of the processes of water infiltration is necessary to control the recharge and quality of groundwater. Empirical and mathematical methods will be combined to estimate the groundwater recharge according to substrate, vegetation and landuse. For this purpose on the open-cast mine Espenhain two soil long-term observation stations under different landuse conditions (forest, agricultural area) were installed. The following parameters are measured in different levels up to 2 m depth continuously every 30 minutes: Soil water content, water tension, soil temperature. On the forest station stem flow and precipitation are determined. On the agricultural area open land precipitation, air temperature, air humidity and albedo are registered automatically. Soil water and rainfall are analyzed on heavy metal contents as well as different cations and anions. Parallel to the field measurements on the institute workstation the computer model WASMOD was used for long-term predictions of groundwater recharge. The WASMOD model is calibrated with the measured data of the observation stations and coupled with a geographical information system in order to obtain groundwater recharge for the Espenhain dump.
