Abstract: Surface overland flow direction in urban area is altered by anthropogenic factors such as land use, drainage systems, roads and other concrete structures and therefore, modeling surface runoff phenomena in urban catchment is much difficult. Complexity of modeling urban runoff has made the designing of urban drainage system a challenging task. A study has been carried out in this study to simulate rainfall driven flow in a sewer system that can cause overflow through manhole and flooding. The simulation is carried out in the Karbala city of Iraq where storm water network is not fully developed. Used Storm Water Management Model (SWMM5.1) for this purpose. The study reveals that a 80 percentile rainfall event causes sewer overflow and surface in the area. It is expected that the study will help in designing and management of urban sewerage system of Iraq.
