In this study, we focused on a small drain catchment in an urban area in Mangalore and simulated the actual conditions of the drain to replicate what is found in the field. An extreme rain event was input into the PCSWMM software to find out the flooding conditions, which were then calibrated based on the flooding that had taken place during this particular rain event. We then redesigned the drains at the required portions to make the flooding conditions zero for the extreme rain event. This work is a small part of a larger project that aims to explore various techniques to reduce stormwater flooding in urban areas using structural, non-structural, and lid techniques. The results of this study provide insights into the effectiveness of this approach in mitigating urban flooding, and can serve as a basis for further research in this area. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.PCSWMMUrban flood modellingUrban flooding
