Paper Details

Storm water is water that originates during precipitation events and snow/ice melt. Storm water can soakinto the soil (infiltrate), be held on the surface and evaporate, or runoff and end up in nearby streams, rivers, or otherwater bodies (surface water). In natural landscapes such as forests, the soil absorbs much of the storm water and plantshelp hold storm water close to where it falls. Storm water is also a resource and important as the world's humanpopulation demand exceeds the availability of readily available water. Techniques of storm water harvesting with pointsource water management and purification can potentially make urban environments self-sustaining in terms of water.The importance of urban storm water modelling is constantly increasing due to three global trends: urbanization,population growth, and climate change. The storm water management becomes more challenging due to urbanization &population growth while at the same time a rising number of people is affected by the harmful effects of storm water onthe environment. SWMM is a dynamic hydrology-hydraulic water quality simulation model. It is used for single event orlong-term (continuous) simulation of runoff quantity and quality from primarily urban areas. The runoff componentoperates on a collection of sub catchment areas that receive precipitation and generate runoff and pollutant loads. EPA'sStorm Water Management Model (SWMM) is used throughout the world for planning, analysis and design related tostorm water runoff, combined and sanitary sewers, and other drainage systems in urban areas. The study aims tosimulate the rainfall-runoff process and design off drainage for urban catchment, the main objectives of this study aresetting up the SWMM (Storm water management model, including relevant data preparation for SWMM), to Study therainfall characteristics, to estimate the runoff of study area, to check the adequacy of existing drainage system and alsoprescribe the smart & sustainable storm water management techniques.
