Aplicación de SIG para la elaboración de mapa multi amenazas y su aplicación en la expansión urbana de la parroquia Guadalupe-Cantón Zamora

Abstract

Abstract: The objective of this research work is to identify suitable areas for a future urbanization in the Guadalupe parish through GIS, in the presence of natural threats linked to external geodynamics or surface terrestrial dynamics such as slope movements and floods. To find the susceptibility model, the bivariate statistical method was applied, by integrating an inventory of landslides in the area and the triggering variables considered, which through validation gave us a success rate of AUC = 69%; Forthe flood model, the hydrological analysis was carried out using Hec-GeoRas and HEC-Ras, where the hydraulic behavior of the Yacuambi River was established against a maximum return flow of 10 years, taking into account the characteristics and physical factors that were identified. present to the channel. And finally, the multivariate statistical method was applied considering the variables of multi-hazards, slope classification and area of influence of rivers; for the identification of urbanizable areas,non-urbanizable areas and urbanizable areas with restrictions, based on the current regulations of the COOTAD and INEN for a correct planning of the territory.
