"Meteorological and hydrological time series spanning almost seven decades from Lange Bramke, a completely clear-cut and thereafter afforested hydrological research basin, were analysed with respect to the discharge regime. The hydrological model WaSiM-ETH linked to a forest growth simulator was used to evaluate the impact of forest stand development on water budgets of Lange Bramke. Climate projections based on the climate scenario RCP8.5 served for the analysis of possible climate change effects on the discharge regime and on the drought stress risk of the Norway spruce stands within the catchment. During the first 40 years after afforestation, observed runoff relative to observed precipitation decreased, whereas simulated evapotranspiration increased. This can almost exclusively be attributed to the increasing water demand of the growing forest stands. Climate models project a temperature rise and corresponding extension of the growing season until the year 2070, which will presumably increase the evaporative demand of the atmosphere. Hereby, the water availability for the forest stands will decrease, and consequently drought stress risk will increase. Under the climate change scenario RCP8.5 the future vulnerability of Norway spruce, which is rated as drought sensitive, will increase." (Abstract)
