Together with continental climate conditions this affects water resources and water users in the region. Driven by scenarios of the regional climate model STAR which assume increasing temperature and decreasing precipitation, two hydrological models, the Soil and Water Integrated Model SWIM and the catchment model EGMO simulate declining natural discharges in the region. Thus, decreasing managed discharges are simulated with the long term water management model WBalMo. The refinement of the simulation time step of WBalMo from months to weeks improves the consideration of climate variability and is also associated with higher simulated managed discharges in early summer. Management scenarios in terms of a reduced outlet capacity of a mining lake reservoir result in higher releases from other reservoirs and slightly reduced summer discharges in downstream river sections.}, language = {en} } @misc{PohleKochConradtetal., author = {Pohle, Ina and Koch, Hagen and Conradt, Tobias and G{\"a}deke, Anne and Gr{\"u}newald, Uwe}, title = {Potential impacts of climate change and regional anthropogenic activities in Central European mesoscale catchments}, series = {Hydrological Sciences Journal - Journal des Sciences Hydrologiques}, volume = {60}, journal = {Hydrological Sciences Journal - Journal des Sciences Hydrologiques}, number = {5}, issn = {0262-6667}, doi = {10.1080/02626667.2014.968571}, pages = {912 -- 928}, abstract = {The Soil and Water Integrated Model (SWIM) was used to assess potential climate and land-use change impacts in the Central European catchments of Schwarze Elster, Spree and Lusatian Neisse which are heavily influenced by opencast lignite mining. To account for potential climate change, scenarios of two statistical regional climate models, STAR and WettReg, were used. Regional anthropogenic change was considered in terms of increasing cultivation of energy crops (oilseed rape, silage maize, sunflower and sorghum) and decreasing mining activities (decreasing groundwater depression cone). In the climate scenarios, decreased natural discharge, by up to 60\% in the long-term average, was simulated. In simulations with climate scenarios and oilseed rape, this effect is halved; the other energy crops have a small additional impact on discharge. The decreasing groundwater depression cone slightly compensates for climate change impacts. Overall, potential impacts of regional anthropogenic activities are secondary to those of climate change.}, language = {en} }
