Natural water erosion hazard for Germany (abatement period 1971-2000)

The natural, average annual erosion hazard by water is calculated according to DIN 19708 with the general soil removal equation ABAG for arable land. For the calculation, the factors R=lowfall intensity (long-year average summer precipitation of the period 1971-2000, DWD), K= soil erodibility (k-factors of the BÜK 1000, BGR, 2005), L=hang length, S=hang slope (DGM 25, BKG, 2007). The calculation was carried out nationwide for a mesh size of 50 meters. The presentation is only for arable land determined on the basis of the base DLM (BKG, 2008). The “natural erosion hazard caused by water for the natural areas of Germany” was derived from the calculation available here. The methodological approach and further results are the UBA text 16/2011 (http://www.umweltbundesamt.de/publikationen/wirkungen-klimaaenderungen-auf-boeden): “Impacts of climate change on soils — Studies on the effects of climate change on soil erosion by water” Wurbs, D. and Steininger, M.
