One major research interest of the DFG research project Regionalization in Hydrology is the problem of spatial parameter relationships relevant for hydrological modelling. In this study, physically based hydrological models and Geo-Information Systems (GIS) have been applied to investigate relationships between geomorphometry and hydrological processes at different spatial scales. The results show the importance of geomorphometry through (a) high correlations of different geomorphometric parameters with hydrograph indices, (b) the relevance of soil-geomorphometry relationships for parameterization in hydrological modelling, and (c) the correspondence of mesoscale landform types to areas showing similarity in runoff production. Scale thresholds related to catchment sizes are proposed.
