%X Runoff processes are very important in the hydrological cycle and have strong influence over many of the physical processes on Earth surface. The runoff is frequently estimated by means of empirical techniques that consider aspects relating to relief and composition of earth materials. This paper propose a new automated methodology for obtaining a homogeneous hydrological zoning mapping based on geomorphometric potential from the digital terrain model. GIS tools were used to perform intermediate indexes: concentration index roughness (ICR), concentration index of drainage channels (ICCD) and concentration index gradients channels (ICGC). The intersection of these three index allows to carry out the Geomorphometric Runoff Potential Map. Comparing with Runoff Potential Map performed in traditional way the proposed map showed good agreement and more homogeneous distribution of runoff classes.
