IDENTIFICAÇÃO DE POTENCIAL HIDROENERGÉTICO EM BACIAS HIDROGRÁFICAS COM USO DAS CARTAS AEROFOTOGRAMÉTRICAS; ESTUDO DE CASO: MICRO BACIA DO ARROIO SOLITÁRIO

This study shows a methodology to identify the hydroenergetic farms in hydrographic micro basin using cartography, exploring the water's flow, the declivities and the contribution areas to the target point. This method is performed only in cabinet, minimizing the costs of field recognition. The curves proximity to the water's flow define the target point and the extension relation by declivity provides the elevation. The contribution area provides the element to determine the outflow, using the curves equation of permanency to regionalized outflow. In the study case of the Lonely Streamlet's micro basin was possible to identify, through the letter, five points with a potential higher than 0,5kw. During the identification of the points, in the field, five of the evaluated points were confirmed and two others were localized and visualized just in the field. The methodology and its reliability can be discussed, and some suggestions to similar works are shown here
