Uso do método processo de hierarquia analítica (AHP) para determinar áreas suscetíveis a alagamento e inundação em Jequié-BA

Abstract

Population growth brings with it several challenges for the infrastructure of municipalities, one of the main ones being the use and occupation of the land, which can lead to several problems, such as floods that affect various sectors directly and indirectly. In this context, the objective of this work is to present the areas with potential flooding within the municipality of Jequié, in the state of Bahia, using the multicriteria analysis ANALYTIC HIERARCHY PROCESS (AHP). In the hierarchical analysis of the process, the variables that must be analyzed are altimetry, slope, land use and occupation and pedology, resulting in the algebra of the maps. With the application of Geoprocessing, carried out through a vectorization process, it is possible to calculate the areas with the greatest probability of occurrence of these phenomena. In which, it identified areas with potential for this risk within the municipality of Jequié-BA, giving a fist to engineering and public policies to solve and predict problems arising from floods.
