Topic of the practice

Assessment of the impact of the climate changes predicted for Saxony on the water and material balances in the catchment areas of Saxon water bodies – Water Balance Section

Good Practice Information

The KliWES project is a good practice introduced by the Saxon State Office for Environment, Agriculture and Geology (LfULG). It covers the assessment of the impact of the climate changes predicted for Saxony on the water and material balances in the catchment areas of Saxon water bodies. KliWES stands for "Abschätzung der für Sachsen prognostizierten Klimaveränderungen auf den Wasser- und Stoffhaushalt in den Einzugsgebieten der sächsischen Gewässer". Especially today where the predicted climate change calls for urgent adjustments to its impacts on a worldwide scale and poses new challenges on the management and prognostics of water resources, KliWES is a good example for how to tackle this issue. The KliWES project started in 2008 as a follow-on project of the well-proven KliWEP (2007) project, which was already focused on the impact assessment of the climate changes predicted for Saxony specifically for the water and material balances in the catchment area of the Parthe river.
The Saxon State Office For Environment, Agriculture and Geology (LfULG) worked closely together with the Technical University of Dresden to jointly develop the methodology and procedure for the assessment and evaluation of the impacts of the climate change on the water balance in the catchment basins of Saxony. So KliWES is an enhancement of the KliWEP project, which was limited to the study of a single catchment area. KliWES is based on a scientifically founded method or combination of several appropriate methods for the calculation of "complete" water balances (based on mean and/or day values) for any of the areas in Saxony, while offering the possibility to run and evaluate scenarios. The results can be used to classify Saxon catchment areas by their water balance's sensitivity to the climate change. In a second step, the results can be used to give region-specific management recommendations to ensure sustainable management of the surface and ground water resources.

Evidence of success

The KliWES project results enable decision-makers to identify the areas in greatest need of adjust-ment strategies for water resources, agriculture and forestry. The results and recommendations from the KliWES project are available to engineering bureaus, industrials, administrations, institutional users, researchers and scientists, politicians and accountants, as well as to national/international bodies and citizens in Saxony. The methodology makes it possible to calculate the actual status as well as climate and land use scenarios. The user is given the possibility to make direct calculations of the effects e.g. of land use changes on the water balance. So a final assessment can be made as to the impact of the climate change on the water balance in the contemplated region under different land use scenarios.
