%X The proper water resources management follows the detailed comprehension of the physical process involved in the water cycle. Recently a large number of remote sensing techniques for observation of hydrological variables has been developed. That enables large and sparse areas monitoring (for example, the Amazon basin), with a superior temporal-spatial cover to the in situ observations. Altimetry is the study of altitude measurements, or the altitude representation in maps or topographical plans. The American satellite ICESat (ICE, Cloud and Elevation Satellite), developed by NASA, was used in this research to perform water level measurements in Brazilian rivers and lakes. The goal of this paper is to evaluate the ICESat utility in hydrologic applications. To reach it, a software was developed to process the ICESat altimetry data, through a routine in Matlab programming language. The resulting code and interface proved to be effective tools to process ICESat data. To validate the satellite data, a comparison was made between water levels obtained by remote sensing and the Agência Nacional de Águas (ANA) gauged stations in the Bananal Island region. It was noticed that the ICESat water level variation approached the ANA gauged stations data, with mean squared error smaller than 30 cm. Another potencial aplications: average slope of the waterline; flood plains monitoring; calibration of hydrodynamic models; leveling staff gauge.
