Diseño del sistema de drenaje pluvial de la Base Naval Norte de Guayaquil

Abstract

The objective of this project is to design a stormwater drainage system for the North Naval Base of Guayaquil by defining hydrological parameters, hydraulic modeling, and environmental impact assessment, in order to reduce flood risk and improve infrastructure resilience. The hypothesis states that the integration of gravity drainage, infiltration surfaces, and a coastal protection dike improves hydraulic performance and reduces long-term costs. The project development was based on the use of available topographic and geotechnical information, as well as updated meteorological data for the construction of IDF curves. The design was carried out following CPE-INEN, EPMAPS, and CONAGUA standards, using the SWMM software for hydraulic modeling. The results showed an estimated flood risk reduction of about 65%, as well as a decrease in the total project cost of approximately 20% compared to a traditional system, with an estimated budget of 1.2 million dollars. Finally, it is concluded that the proposed system is technically, economically, and environmentally viable, becoming a sustainable and replicable solution for the northern area of the city of Guayaquil.
