EROSION 3D (modelling soil erosion by water)

MODEL APPLICATIONS (examples)

Phosphorus loss

Prediction of muddy floods in urban areas

Arévalo, S. A. 2009

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).

Area related outputs • Erosion, deposition and net erosion [kg/m²] • Excess rainfall [m³/m²] • Depth of wetting front [m]

Outputs related to cross- section of flow

• Runoff [m³/m] • Sediment delivery [kg/m] • Sediment concentration [kg/m³] • Particle-size distribution of the suspended sediment [M.-%]
