Abstract:
To provide a solution to the flood problem in the locality of San Pedro, it is important to control the evolution of flood zones by taking into account natural and anthropogenic factors through flood risk maps. A field survey made it possible to compare the results of the GIS with the realities on the ground. The flood risk maps were produced taking into account the city’s flood vulnerability and flood hazard maps for the different years (1980, 2000 and 2020). Using Saaty’s AHP method, parameter weights are calculated and superimposed to obtain the flood risk map. For the field survey, it was done by probabilistic spatial sampling. The results showed that over the past four (4) decades, the city’s high-flood risk areas have tripled. As the city’s urbanization increases in San Pedro, the risk of flooding increases.
