Hydrologic -Hydraulic Study for an Urban Project Adjacent to a River with no Base Flood

Abstract

The massive land development increases the impervious areas of watershed, which induces high runoff and downstream flooding problems especially in areas adjacent to a river. It is extremely important to determinate a federal regulatory floodway in these areas in order to regulate the urban development without control in this zone to ensure that there are no increases in upstream flood elevations neither downstream. This paper intends to show the studies and the procedures required to conduct a large-scale urban project adjacent to the river where there is no established base flood in order to comply with existing regulations for this area. Key Terms - hydrology and hydraulic studies, mitigation, detention pond.
