Evaluación hidrológica de la zona de influencia de la quebrada Balsas en el cantón Balsas para la determinación de factores y mapas de riesgo de inundación

Abstract

The purpose of this research work is the determination of flood hazard and risk maps, in addition to flood risk factors for the area of influence of the Balsas stream in the Balsas canton. The maximum flows for each return period ,T= 5, 10, 25, 50, 100 years, were obtained through the rational method and the haracterization of the basin through ArcGis to obtain the weighted coefficient of runoff and the intensities through of the IDF, resulting in flows of 169.76, 195.45, 241.24, 281.48 and 333.25 m3/s with respect to the return periods. For the modeling of the channel, the RAS Mapper software was used and for the simulation the HEC-RAS software, obtaining values of flood levels of 4.14, 4.20, 4.27, 4.33 and 4.42 m with respect to the return periods.
