Resumo


The intensity to which natural phenomena have been occurring and surprising the population imposes on Engineering the search for preventive measures that minimize the contingent of people affected by these tragedies. It happens due to the imminent risks of disasters, posed by rain combined with the soil properties, declivity and the type of land use and land cover existing in the region. From this perspective, an experimental program aimed at issuing warnings is justified from the technological point of view. Therefore, the present work presents an elaboration of a monitoring system to analysis and alert generation of risks for the city of Ouro Preto - MG, based on TerraMA2. The project used for the elaboration of analysis models precipitation data obtained by data control points and by hydro-estimator. In additionit was used a case study with 33 occurrences of slope disruption in the city of Ouro Preto. The obtained results showed that the generated model would be effective to identify imminent risk situations.
