Model builder for Percolation characteristics

The model builder is used to modify Curve Numbers (CN-values) assigned to individual grid cells of the raster based rainfall/runoff model.

For percolation, only a single parameter is used to determine the CN-values:

However, it has to be considered, that in the calculation of the daily runoff balance, percolation is calculated after direct runoff. Thus, there is also an indirect influence of land use and climatic zone.
