Abstract

The research project consists in evaluating the use of orbital radar data in the comparative study of two distinct aquatic environments, one little altered by man (Lago Grande in Monte Alegre) and the other resulting from the construction of an artificial lake for the generation of electricity (the reservoir of the Tucuruí Hydroelectric Plant). The project envisages the simultaneous acquisition of field data and images from the Radarsat, JERS-1 and ERS-1 satellites. The field data will be used to characterize the environments. We will then make estimates of the potential for the emission of methane based on data from the space field with the help of information on the area occupied by aquatic plants, water and flooded forest extracted from images.
