Análisis de la susceptibilidad frente a los movimientos de ladera con la aplicación de herramientas SIG, en la parroquia Saraguro del cantón Saraguro

Abstract

Abstract:The research focuses on developing a susceptibility model to evaluate future slope movements in the Saraguro parish through Information Systems Geographic (GIS). The study combines GIS tools with UAV and GNSS technologies to map and characterize terrain displacement zones. The methodology implements a bivariate statistical analysis, integrating variables conditioning factors such as slope, lithology and land use. Base maps were created and thematic from geological, lithological, geomorphological and topographic surveys, using UAV and GNSS technology. The results revealed that factors such as slope, soil cover and lithology have a significant impact on landslide susceptibility. The bivariate model It achieved a reliability of 86%, surpassing the matrix method in accuracy. The GIS tools were effective in identifying high-risk areas, while combination of GNSS and UAV allowed measuring daily displacements of up to 0.006 mm. He study provides a solid basis for geological risk management in Saraguro.
