Abstract
The Agricultural Non-Point Source Pollution Model (AgNPS) and the Revised Universal Soil Loss Equation (RUSLE) were used as tools to predict spatial and temporal variability in surface runoff and soil erosion risk. The distributed model AgNPS allows the spatial evaluation of runoff and soil loss for single storm events. The Integrated Land and Water Information System (ILWIS) was used in a GIS-model link to determine and handle the distributed model input and output of AgNPS. This paper focuses on the regionalization of topographic input parameters and the application of the AgNPS hydrological model for six different spatial resolutions ranging from 200 m to 1 km. The test area is the 211 km2 Guadalteba River basin located in the province of Malaga, Spain. This drainage basin was chosen because there is much surface runoff and soil erosion in this region.
