Abstract | |||||||||
| In this study two approaches are presented to model Dominant Runoff production Processes (DRP) with respect to regionalization. The approaches have been developed in the micro-scale experimental Zemmer basin (Germany). The first approach combines the permeability of the substratum, land-use and slope of the basin in a GIS-based analysis. The second approach makes use of discriminant analysis of the physiographic characteristics of the basin and links it to the GIS analysis. The net results were two maps indicating modelled DRP for the Zemmer basin, which were then compared to an existing DRP map of the Zemmer basin. Both approaches provided satisfactory results when compared to this existing DRP map. The first approach was strongly linked to the geological conditions of the basin while the second approach revealed a strong dependence on the topography. Therefore, impermeability of the substratum and the topography of the basin were used as suitable parameters for modelling dominant runoff processes. | |||||||||
