Abstract

Starting in 1987, comprehensive investigations in the 4.2 km2 Lehstenbach catchment in the Fichtelgebirge (South Germany) were performed to determine water and matter fluxes. The catchment is nearly totally covered by Norway Spruce stands. The measurements indicate that the vertical profile of groundwater flow is strongly heterogeneous: lateral flow in the upper aquifer layers seems to prevail. As the upper layers show marked acidification, only a small portion of precipitation water infiltrating during storm events can be buffered here, resulting in acidic catchment runoff. On the other hand, this implies a remarkable retardation of acidification of the deeper layers. The purpose of this paper is to investigate the hydrological specifics of the catchment, especially to identify and characterize the flowpaths. To that end, we use two different modelling approaches. Results of these model runs can be used to assess the impacts on hydrochemical models.
