Resumen

La información hidrológica es esencial para estimar la magnitud de las inundaciones y contribuir así a reducir las pérdidas y los daños. Sin embargo, cuando estos datos son escasos, la modelización de inundaciones y la evaluación de riesgos se convierten en un reto. En el oeste de Rio Grande do Sul, utilizamos la cuenca del río Santa Maria para estimar el caudal del río para diferentes tiempos de retorno, basándonos en la distribución estadística de los datos de precipitación y caudal del río, y para simular escenarios de inundación utilizando un modelo hidrológico IBER 2D. Los resultados mostraron una alta correlación entre los caudales calculados a partir de la precipitación y los datos fluviométricos, utilizando la
distribución GEV y GumbelMax. Las áreas susceptibles de inundación son consistentes con eventos de inundación pasados, validados con trabajo de campo e imágenes Sentinel. Los caudales fluviales estimados a partir de los datos pluviométricos pueden favorecer los estudios hidrológicos en ausencia de datos fluviométricos.
