The trough loss (MV) is specified by the user. The standard and simultaneously maximum value in the model is 4 mm. The trough loss represents the average value for an sloping surface. However, since the troughs are not evenly distributed and, as experience shows, drainage begins before the complete filling of the troughs has been reached everywhere, it is assumed that
- 1/3 of the sealed surface has a reduced trough loss of 1/3-MV
- 1/3 of the sealed area the average trough loss of 3/3-MV
- 1/3 of the sealed surface has an increased trough loss of 5/3-MV
has. Therefore, runoff already occurs when the precipitation reduced by the evaporation rate exceeds the wetting loss and 1/3 of the trough loss (in case of dry history). The assumptions above are schematically sketched in the following figure.
