| Abstract | The intervention and degradation of the environment has accelerated in modern times through technical capabilities. The objective of the presented study is the evaluation of different stresses on the hydrological processes and water balance of a small research catchment in a German low-mountain environment since the beginning of hydrological records in 1968. The research catchment "Schaefertal" is located in the Harz Mountains, NE-Germany, approximately 150 km southwest of Berlin. The outlet of the 1.44 km2 catchment is at 392 m a.s.l. The orthic luvisols and cambisols, which have developed on the loess sediments on slopes, underlie agricultural use, whereas the eutric gleysols and fluvisols at the valley bottom are used as pastures and meadows. A hydro-meteorological station is the backbone of the research station which started recording during the International Hydrological Decade in the late 1960s. Detailed analyses of the hydrograph and groundwater measurements allow the separation of three periods with distinct differences in water balance and runoff generating processes. Until 1973, hydrology is characterised by a well-balanced water flow. The base flow contribution guaranteed a minimum of water flow in summer time. The following periods were characterised by plot realignment, draining of a pasture area, and the opening of a mine causing a decrease of the regional groundwater level. This entailed a hydrological situation with long dry periods and episodic flash floods. In the course of the safekeeping of the mine, the groundwater level has been rising again since 1993. |
