Erosion hazard due to water
Description
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. Subsequently, an average of the hazard was calculated for the natural spatial units (BFN, as of 2008), which is shown here. The presentation was presented only for arable land determined on the basis of the use-differentiated soil overview map for Germany (BÜK 1000 N, BGR, 2007). The level of the natural spaces was chosen to further determine the “use-dependent erosion hazard” because data on the actual fruit species spectrum could only be used at this level. 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. (2011).
