The aim of this work was to analyze the morphometry and the type of use and occupancy of the basin Carão reservoir, located in the municipality of Tamboril - Ceará, seeking to understand the natural and anthropogenic processes acting in this enviroment, favoring thus the development of conservation plans and natural resources management. The reliefs morphometric characteristics and the basins ways to use and occupation were obtained by the software ArcGIS 9.3\uae, from techniques of remote sensing and GIS. The basin is considered small, with estimated area of 309.55 km2 and 103.16 km perimeter. Among other things, an elongated and narrow shape was verified, with low drainage density and flat terrain and slightly wavy, whose slopes are presented below 20%, configuring thus so little disposition to flooding in the basin. It was observed a relationship of use and occupation targeted by the lower slope of the terrain and hydrographic presence,determining a bigger pressure by humam activities in these areas, representing a potential modifier of the water quality of the reservoir Carão. Relationship was observed for use and occupation targeted by the lower slope of the terrain and the presence basin, causing increased pressure in these areas by human activities, representing a potential modifier of the water quality of the Carão reservoir.Pages: 8138-814
