             abstract = "In some regions of Brazil, the existence of a large number of 
                         small reservoirs distributed in the same basin has a crucial 
                         importance for water supply. The two regions with the highest 
                         concentration of small reservoirs are the extreme South of Brazil, 
                         where theres an excessively high water demand due the rice crop 
                         irrigation, and the semi-arid Northeastern region, where water 
                         shortages require the construction of many reservoirs. For 
                         managing the use of these resources in the medium and long term, 
                         its essential the availability of water level or volume data 
                         monitoring, as well as historical series of these values. However, 
                         the scarcity of in-situ gaging stations makes the use of remote 
                         sensing an alternative to obtain reservoir data records. Satellite 
                         radar/laser altimetry is a technique that can be used to estimate 
                         water levels of open water bodies. In small reservoirs, with a 
                         surface area around 100 hectares or smaller, the restrictions for 
                         the use of altimetric sensors increase due the spatial resolution 
                         of most these sensors used with hydrological applications. This 
                         work presents an approach to determine the storage volume 
                         variation in small reservoirs, combining satellite altimetry from 
                         the ICESat mission data, as well as image processing techniques. 
                         These techniques are related to the extraction of reservoir 
                         surface area from optical sensors, more precisely from Landsat 
                         images. The comparison with the water volume obtained from the 
                         hydrological modeling and water balance demonstrate a good 
                         relation with the simulate data and estimated from satellite.",
