OPTIMAL SIZING OF URBAN FLOOD-CONTROL SYSTEMS

Optimal sizes for components of urban flood-control systems can be determined from a detailed simulation analysis controlled by an optimization methodology. Flood-control measures within urban areas frequently consist of complex systems of detention storage reservoirs, channel modifications, levees, land-use controls, flood proofing, and pumping facilities. The optimal size of each of these system components depends on the system interaction with other components and the hydrologic, economic, environmental and other performance outputs of the system. A technique has been developed and programmed for an existing simulation model that automatically determines the sizes of urban flood-control components of detention storage, flow diversions, and pumping plants that result in maximizing system net benefits subject to accomplishment of hydrologic performance targets. The system is simulated using hydrologic data, component cost and performance functions, and flow damage information at damage centers.
