Evaluación de los riesgos por inundaciones en zonas con influencia a cuerpos de agua y movimientos en masa en el área urbana Piñas

Abstract

Abstract: This study evaluates the multi-hazard risk associated with flooding influenced by nearby water bodies and mass movements in the urban area of Pinas. The research aimed to identify critical areas and propose mitigation measures to support emergency management. Geographic Information Systems were used to generate susceptibility maps and to assess exposure and vulnerability. Susceptibility to mas movements was modeled using the Information Value (Wi) statical method, considering topographic, geological, and morphometric variables. Flood susceptibility was estimated using hydrological and geomorphological parameters derived from terrain characteristics and proximity to water bodies. By integrating these results, areas exposed to multi-hazard scenarios were identified. Subsequently, the exposure and vulnerability of housing located in zones with very high susceptibility to were evaluated. The findings highlight limited coordination between urban planning and risk management processes. Based on these results, strategies were proposed to strengthen emergency preparedness and contribute to more effective territorial planning.
