| dc.description.abstract | Flooding has long been recognized as the most damaging and costly natural hazard in many countries considering the frequency and influencing extent. Due to the rapid urbanization and the global climate change in the urban areas, the frequency of devastating floods tends to be higher and the loss of human lives and property show no sign of decreasing. In order to decide on minimizing the impact of floods an effective flood volume estimation model is required. The proper design of any storm drainage system involves the accumulation of certain basic data, familiarity with the project site, and a basic understanding of the hydrologic and hydraulic principles and drainage standards associated with that design. The rational method is the most common method in use for the design of storm-water drains, where the momentary peak flow rate is desired. The method provides peak runoff rates for small urban and rural catchment areas, less than 50 hectares (0.5 km2), but is best suited to urban storm-water drain systems and rural ditches. It shall be used with caution if the time of concentration exceeds 30 minutes. For the study area the storm-water sewer network has been analyzed based on the selected outfall facilities, selected network schematization and agreed designed criteria using interactive mathematical model on Excel. This study shall contribute a lot to control the flooding problems of the study area and enhances the ability of planners, researchers and city development actors to formulate and implement sound policies to minimize undesirable future flooding impacts and management alternatives. | en_US |
