Diseño de bypass norte de regulación de caudales extremos del Río Garrapata, Chone, Manabí

Abstract

CONDITION FOR PUBLICATION OF PROJECT. Flooding in the city of Chone is a recurrent problem due to the confluence of the Garrapata, Mosquito, and Grande rivers, whose regulation capacity is limited during periods of intense rainfall. Based on this context, the project aimed to design a northern bypass to reduce overflows and strengthen the city’s water security. The hypothesis established indicates that the use of hydrological, hydraulic, and geotechnical modeling tools facilitates the definition of viable and sustainable solutions to address flood risk. For the development, topographic, hydrometeorological, and geotechnical data were collected and processed using rainfall-runoff and hydrodynamic simulations, complemented with local regulations and field verifications. The results allowed the characterization of extreme flows in the basins and the simulation of flood dynamics in the urban area, identifying the most vulnerable sections. Based on these analyses, the Northern Bypass was designed, whose implementation will significantly reduce flood hazards and strengthen the social and economic resilience of the population.
