Influence of Low-Impact Development in Flood Control: A Case Study of the Febres Cordero Stormwater System of Guayaquil (Ecuador)

Urban flooding is a major problem in many coastal cities. The rapidly shifting patterns of land use and demographic increase are making conventional approaches to stormwater management fail. In developing countries such as Ecuador, lack monitoring, financial constraints absence proper policies exacerbate problems. This work assesses the implementation two Low Impact Development strategies (LIDs), namely, green streets rain barrels, nature-based solutions mitigate “Stormwater Management Model” (SWMM) helped contrast new approach with current state drainage system, including normal extreme scenarios. With an 1.4% (19.5 ha) total area LIDs, reduction runoff for short events (200 min) around 20%, (within 24 h) 19% comparison approach. Flooded nodes were reduced 27% events, 4% events. peak system had 22% 15% These highlights help city resilience, authorities stakeholders should engage climate actions reduce flood risks complementing operations solutions. Moreover, calibrated results this article serve awareness among municipal regarding importance maintaining records improve modelling decision-makings processes.
