Susceptibility to flooding in abdon calderon of canton portoviejo parish

Abstract

This research was developed in the field of risk management against floods with the application of Geographic Information Systems (GIS) to assess the susceptibility to flooding in the central part of the Abdón Calderón parish of the Portoviejo canton where there are geographical and climatic characteristics that create favorable conditions for the occurrence of this phenomenon (slopes, edaphic composition with significant presence of clay and existence of patterns of intense rainfall in the winter season. Work was proposed to determine the susceptibility to flooding to which the research area is subject through the analysis of cartographic data and the thematic maps of slope and soil with a weighting methodology of the importance of the mentioned variables according to the qualitative evaluation. Iva carried out preliminarily through observation visits and taking of reference data in situ. The result was the obtaining of a susceptibility map where the high, medium and low susceptibility level can be observed in the downtown part of the Abdón Calderón parish.
