Estudio de factibilidad de un sistema urbano de drenaje sostenible en la vía 10 de Agosto, ciudad de Machala

Abstract

In recent years, urbanized areas have been flooded due to climate change and urban growth, in order to obtain a better control and reduction of floods, through a Sustainable Urban Drainage System (SUDS). At present, no solutions have been applied to flooding in the city of Machala. The purpose of this technical work is to propose a sustainable urban drainage system to minimize the impact of these rainfall events in urban areas of the 10 de agosto road and other adjacent streets. First, research was done through scientific articles about the applications, techniques or methodologies that could help us to choose a better service proposal for the inhabitants of the study area. A hydrological/hydraulic analysis was carried out where maximum flows of the sub-basins were obtained for return periods of (5, 10, 25, 50, 100 years), however, it was decided to design the SUDS for a return period of 100 years. Epa Swmm 5.2 software was used for the modeling of the sub-basins, where green roofs were designed for the impervious areas that exceeded 90%. Runoff values of 378.18, 374.78, 376.78, 376.78, 933.80, 377.95, 377.95, 377.88, 377.88, 376.89, 385.18, 385.18, 377.68, 378.49, 372.17 mm were obtained. 17 mm and a reduction percentage greater than 70% was obtained, and values of the flow rates 2.17, 2.37, 4.8, 3.36, 13.58, 2.60, 2.54, 3.28, 4.35, 2.29, 2.28, 5.73 and percentage reduction greater than 58% was obtained
