ABSTRACT:
Understanding the physical environment is essential in planning and management of territory. The physical analysis of the landscape is performed through several interconnected elements, such as soil type, relief, drainage density, mineral resources, use and occupation from soil. In recent decades, the construction of large and medium-sized hydroelectric dams has become constant in the country's river basins, allowing the generation of electricity in all Brazilian regions. The discussions about the planning of the territory should aggregate the specific knowledge that is extremely important for the environment appropriation in a less impacting way. This study presents a survey of the physical characteristics of the Rio Corrente water basin and a survey of potential and emergent instability environments, established from the application of Ross's methodological proposal (1994). Thus, the present proposal aimed to detect the areas with the highest and lowest degree of Potential and Emerging fragility, and to raise the impacts that may be caused in the area of influence of the Espora Hydroelectric Power Plant (UHE) located on the border of the municipalities of Serranópolis and Aporé/GO. As a result, it was detected the predominance of Latosols, sandy and medium texture, distributed in flat to undulating areas, occupied by extensive areas of pastures and monocultures, such as corn, soybeans and sugar cane. Potential fragility due to soil, rainfall and slope were classified as 96.7% low, 3.16% very low and at an average level only 1.23%. However, emerging fragility showed that land use significantly impacted increased soil impacts, especially in agricultural areas, increasing environmental fragility, characterized by 40.4% average and 44.1 low, only 1.54% very low.
