Resumen
Different software for Geographic Informatiori Systems (GIS), such as ArcView and ArcInfo, are available nowadays. They provide tools not only for watershed and stream network delineation, but also for the automatic calculation of their physical and geometric properties based on topographic surfaces called Digital Evaluation Models (DEM).In this context, this paper presents the basics of DEM's, explains the conceptual framework of watershed delineation, and illustrates the methodology to be followed through the application of basic commands of ArcView and ArcInfo to a geographic area
