Description

Project section 3.2.1 ‘The Water Balance in Reservoir Catchment Areas’ concerns the quantification of the effects of climate change on the quantity and quality of reservoir inflow within the REGKLAM model region. The research with respect to the water balance components will form the basis for subsequent adaptation and mitigation strategies for future reservoir management, raw water processing and water related land use management within the catchment area. The Institute for Hydrology, TU Dresden, will research the quantitive components of the water balance for climate and land use scenarios. The chair for Location ecology and plant nutrition will research the qualitative water aspects.

The catchment areas of the Klingenberg/Lehnmühle reservoir system will result in models which will show the influence and effects of future expected meteorological / climate boundary conditions on the reservoir discharge and water quality. Possible consequences resulting from changes in land use management will also be researched. The potential changes in water balance components and the extreme flood and drought events will be analysed statistically and stochastically and assessed in regard to the management of the multi purpose reservoir Klingenberg /Lehnmühle in the eastern Erzgebirge (the eastern Ore Mountains). On the basis of this research work and in conjunction with the regional reservoir management headquarters of Saxony, a multi criteria system will be masterminded for decision support and the optimisation of reservoir management and control measures under varying meteorological boundary conditions and climate change impact.
