Resumo

There are various models of landscape evolution (LEM), which consider and analyze various environmental parameters during a long time scale. The present paper applied a simple LEM to the nuclear power plants installation site of the Angra dos Reis ? RJ and analyzed the soil surface changes at this site during 1500 years. The simulation results show that the duration of 1500 years is not so long to transform rocks in soils and that the study area would not suffer from a large change of the land elevation. In the simulation, the soil depth was initially set larger at the coastal zone and smaller at the top of the mountains. After 1500 years, the lower and higher areas in the study site have more erosion and a small change of elevation was verified in most of the study area. In case of the simulated scenario, the predicted surface changes were insignificant for the Angra dos Reis power plants area.
