Abstract
The main purpose of this study is to investigate surface inundation with the consideration of water surcharges from drainage systems. Moreover, detention pond
model is taken into account to analyze the flooding areas for various return periods of flood.
Storm Water Management Model (SWMM) is employed to solve the storm sewer flow component and to provide the surcharged flow hydrogaphs for surface runoff exceeding the capacity of the storm sewers. The 2-D diffusive overland-flow model considering the non- inertia equation with alternative direction explicit numerical scheme is then used to calculate the inundation zones and depths due to the surcharged water on overland surface. Detention pond model deals with outlet work of rectangular orifices and weirs used for solving hydraulic equations to provide the outflow hydrographs of the detention ponds. In order to present better performance of the results, geographic information system (GIS) is employed to display simulated results.
