Gestão de recursos hídricos em bacias hidrográficas: Representações computacionais do ciclo hidrológico em Sistemas de Informações Geográficas

Abstract

The paper had the objective to implement a numeric computer simulation of the superficial flow of, transforming a GIS into a realistic system of the time-space. This study fits in the activities predicted by the Fundo Setorial de Recursos Hídricos, through the managing of the hydric resources in South Brazil. One area establish by CT Hidro is the land use and cover changing and soil conservation at water systems where the main problems are the soil erosion and soil compaction, loses of the natural cover and improper reforestation. With that, the program tries to provide the development of conservationist practices and the prevention of the water sources at watersheds. Between the results, the great superficial waterflow, being approximately 46,32% (90.500.000 m³) of the total of the water is lost.
