RESUMO

This paper presents a method for the determination of flooding parameters in hydroelectrical reservoirs. The method is based on the integration of Digital Terrain Model (DTM)and Remote Sensing data derived from JERS-1/SAR. The area and volume of the reservoir, considering different water levels, were determined using SPRING, a Geographical Information System software developed by the National Institute for Space Research (INPE). The method was applied to the Serra da Mesa reservoir - which has been in operation since April 1998. The results showed a systematic error in reservoir project. The volume and area values are 30 percent smaller than those projected. The results, if validated, shows that the generation of energy is below the previously predicted, and that the flooding area is smaller than that announced.
