Stormwater Control in a City Built Over Wetlands

Imagine a City in a coastal plain of the Pacific Coast of South America with wetlands in a vast part of its area. Now imagine that you are asked to provide stormwater control for it. This paper presents a rigorous methodology used to accomplish just that. The City of Guayaquil is working very diligently to re-establish “smart planning” for managing its stormwater, eliminating/reducing flooding damage, reducing the number of people living on high-risk areas and increasing agricultural land beneficial usage.A detailed description of the sequence and methodology of analyses is also described in this paper. The project based on a “road map” with five (5) mayor tasks: The analysis of the current legal framework and planning policies, a comprehensive study of the watershed characteristics, the development of a state of the art hydrological and hydraulic model, model simulation of different floodplain scenarios and the final stormwater management plan.
