Abstract


Urban flooding is the submergence of an area by a large amount of water that comes from sudden excessive rainfall. As a result, it overwhelms the capability of the drainage system, such as storm sewers. Surat city is located on India’s west coast at the mouth of the Tapi River. Surat city has faced many floods for a long time. The main aim of the study is to simulate the existing stormwater drainage system and to identify any overflowing manholes in Surat City (West Zone) by employing the Storm Water Management Model (SWMM). SWMM is an effective tool for simulating urban floods. In the present study, rainfall data for 2018, 2019 and 2020 and stormwater network data were used to evaluate the present stormwater drainage network. The above data are then imported into SWMM to display the inversion level and drainage network details. The flow direction has been assessed from these inverted-level drain network characteristics to produce a descriptive view of the study area. From the above analysis, it is found that some parts of the western zone are mostly affected by flooding. These flooding conditions can be improved by increasing the dimensions of the conduit pipes of the respective drainage system. Recommendations and suggestive measures are provided to improve the resilience of Surat city against floods.
