EROSION 3D (modelling soil erosion by water)
MODEL APPLICATIONS (examples)

v
EROSION 3D is a pysically based soil erosion model for catchment-scale simulations. It was delveloped based on the slope version EROSION 2D. Predicted processes:
• infiltration • runoff • detachment • transport • depositon
… for single storm events.
In- and output parameters are grid-based and can be processed in GIS.
Optional submodules: • multy-layer infiltration • kinematic wave • long term simulation • snow melt and frozen soil • retention basin

MODEL INPUTS
Soil
• texture [M.-%] • bulk density [kg/m³] • initial soil moisture [V.-%] • org. carbon [M.-%]
• erodibility [N/m²] • roughness [s/m1/3] • cover [%] • skin factor [-]
Precipitation • intensity of rainfall [mm/min] • duration of rainfall [min]
PARAMETRISATION A data base was elaborated during the soil erosion measurement program in Saxony (1992-1996).
These data are documented in the parameter catalogue of Saxony (Michael et al., 1996).
