GEOMORPHOLOGICAL MAPPING FOR URBAN SLOPES AND MASS MOVEMENTS IN THE CITY OF BRANQUINHA, ALAGOAS

Abstract

Hillsides in urban areas are not easy tasks to map. This phenomenology requires that the researcher has techniques to characterize conditions such as the topography, geology and climatology of the area in question. Disasters can be caused by natural phenomena associated, at first, with more global events such as earthquakes, tsunamis, volcanic eruptions and hurricanes, but can also occur due to more localized processes and phenomena, such as floods, drought/drought, mass movements, among others. These processes may also be associated or induced by human activities, mainly due to disordered occupation. Thus, this article had as general objective to map risk areas in the city of Branquinha, Alagoas from mass slippage. As a method, Tricart's Ecodynamics (1977) was the reference.Na metodologia foram trabalhadas atividades de campo, entrevistas com moradores e aplicação de questionários. As a final proposal of the research, a graph was constructed to facilitate the understanding of the socio-environmental situation of the residents and the preparation of a synthesis map of the areas of slippage that proposes stability measures for these environments.
