Caracterização morfológica da bacia hidrográfica do ribeirão santa bárbara, goiás

Abstract

A watershed is the place where every water or soil use made upstream reflects downstream. Because of that, it is the best geographic space for water resources management and planning. It is crucial to identify the geographic and topographic characteristics of a watershed, because those aspects affect its hydrological behavior. In this study, the main Santa Bárbara River watershed characteristics were obtained by using a Geographic Information System (GIS), on a 1:100,000 scale digital map, and satellite images. The procedure showed to be appropriate to obtain physiographic characteristics and average rainfall levels in small watersheds.
