Detailed Description

Soil erosion modelling with a modified MMF (Morgan-Morgan-Finney) model (Morgan & Duzant 2008).
This tool is called MMF-SAGA because some things have been implemented differently compared to the original publication. The most important are:

  • the extension of the model to support spatially distributed modelling
  • the introduction of a "Channel Network" layer
  • the introduction of a "rainfall duration" (time span) parameter
  • the exposure of the flow depth parameter


A more detailed description of the model, its modifications, and model application is provided by Setiawan (2012), chapter 6.
Currently, a number of additional grid datasets are outputted to facilitate model evaluation. This can be easily changed within the source code.
