Abstract In the eastern Thuringian Basin, the low precipitation rate of 585 mm/y limits the groundwater resources in the sandstone aquifer system. The aim of this study was to develop a groundwater flow model for the region in order to forecast the impacts of different climate scenarios on the groundwater balance. Since recharge is of high relevance for the numerical model, a time series of groundwater levels were investigated to obtain the recharge input function. In the sandstone aquifer it could be shown that groundwater flow is characterised by flow in the fracture network as well as in the matrix. The largest fraction of recharge reaches the water table very quickly via the fracture network. However, both the thickness of the unsaturated zone and the low hydraulic conductivity of the sandstone matrix control the time lag of groundwater recharge. The time lag of the slow component to reach the water table is in the order of several years
