MULTI-SCALE RAINFALL-RUNOFF MODEL FOR SIMULATING FLOOD DRAINAGE NETWORKS

Abstract


The objective of a storm drainage design, is to provide a safe travel of vehicles and pedestrians as well as protect properties from being damaged during a storm event. The storm water runoff should be collected by the storm drainage system, and then conveyed along the right of way through a conveyance system, to be discharged at a disposal point without being destructive. In order to achieve these objectives, the planning and coordination of storm drainage systems must begin in the early phases of urban planning. Integrating urban plan and storm drainage planning results in successful development of an effective, efficient and economical storm drainage system. When designing urban storm drainage systems which include catch basins, manholes, pipes, etc, these systems are designed to convey runoff from storms of high frequencies (2 to 10 years). Whereas, main collector drainage systems comprising of open channels, natural streams, valleys, and ponds are designed to accommodate runoff from less frequent storms (100 years). During 100-year rainfall event, the drainage system is not capable to divert the incoming hydrograph to the main collector, and the storm drainage network can become surcharged and flooding will occur. Therefore, an accurate estimation of the flow discharging into a main collector is needed in extreme rainfall events to attain a value engineering design A methodology was investigated to realistically estimate the flow at a
