The objective of this study is a physically based analysis of runoff generation processes in dependence of relief, slopes deposits and antecedent soil moisture dynamic in the point and slope scale. Due to these scales important and negligible geo-factors will be distinguished and rules for their influence will be derivated. The analysis of the runoff processes is based on perennial and constant measurements of precipitation, runoff, groundwater and soil water potential with a temporally high reso-lution (10 minutes) in the catchments "Obere Brachtpe" and "Bohläse" (Sauerland, Germany). The investiga-tions are focused on runoff generation processes which mainly occur in a humid mountain climate. Additionally to these measurements hydrochemical and tracer methods were used to determine the residence times and flow paths of the groundwater. The heterogeneity of both catchments gives the opportunity to compare the influ-ences of the relief, the slope sediments, the soils and the antecedent soil moisture on the runoff processes.
