Estudio hidrológico e hidráulico de la quebrada Quilloyacu para la prevención y mitigación de inundaciones y flujo de sedimentos

Abstract

Abstract: Torrential flows are a crucial issue for communities, especially those located in areas prone to erosion and landslides. In the city of Loja, sediment production in the Quilloyacu Creek represents a constant risk for the area's residents. The lack of prior studies and the need for alternatives to mitigate this hazard motivated this study. A detailed hydrological analysis of the watershed was conducted, revealing significant flood flows and a considerable volume of sediment. To mitigate the effects of these sediments, the construction of two dams was planned: one in the upper part of the watershed with a retention capacity of 22% of the total sediment production, and another in the lower part with a capacity of 40%. In conclusion, storms generate significant sediment production, constituting a risk for downstream populations. However, the implementation of the proposed remedial works will effectively reduce this risk, improving community safety.
