摘要：

A method is presented that delineates spatial units with the same dominating runoff generation processes at meso-scale, mountainous basins. It is applied to two basins (40.12 and 17.81 km(2)) in the Black Forest Mountains, south-western Germany. The characteristics of the soil and drift cover and the topography served as main criteria to identify runoff generation units. The method is based on previous experimental investigations including tracer studies. The comparison of the two neighbouring basins showed the plausibility of the method. One catchment has a larger runoff response than the other, which is documented in specific flood runoff values and the spatial delineation. Finally, the potential of such a spatial delineation for distributed hydrological models and further practical issues is discussed. (C) 2003 Elsevier Science Ltd. All rights reserved.
