Sediment balance index (10 m grid) (WMS service)
Description
The sediment balance index presented here is based on that of Möller et al. (2008) and is a further development of the method described by BÖHNER & SELIGE (2006). The basis for this is the combination of different relief parameters, whereby parameters of the soil (soil type), precipitation or land cover are not taken into account in the application. The calculation is based on the basic idea of the LS factor of the USLE (WISCHMEIER & SMITH (1978)). The slope slope is integrated via an equivalent of the sediment transport index (STIS). The slope length flows in via exponent values for flat slopes (SCHWERTMANN et al. (1990)). The sediment balance index thus describes a relative potential of the relief for removal (index -4 to <1) or accumulation (index >1 to 4.5) of soil material. Further developments are carried out by MÖLLER et al. (2008) is described.
