In 2010, Palmares city, located in the state of Pernambuco, suffered an extensive environmental impact due to a strong flood of the Una River, with major repercussions for resident population. This work presents a post-flood socio environmental situation, due to this event being considered of high magnitude. For this was used the RapidEye spatial high-resolution satellite image of year 2015 to check the occupation of the area, contrasted with on-site visit and the data of Floods Susceptibility Maps belonging to Geological Survey of Brazil – (in Portuguese CPRM), which enabled us identify the area classification as of high, medium and low risk. In this context stand out that interventions had been taken by the government to combat and minimize new flood due the risk area for the population. The development Floods Susceptibility Maps and Digital Terrain Models (DTM) are necessary to forecasting of risk for this were used. From the analyzes it was evidenced that the population continues to occupying many affected areas by floods and that even with the public projects development to combat the floods, the region is still very vulnerable. Therefore, the affected areas monitoring is a substantial factor to detect the impacts and to forestall the future risks. It is noteworthy that all products were generated from the high-resolution image data, which allow a better interpretation of area and improve in the projects
