The Integrated 1D-2D PCSWMM is used to examine the inundation velocity and depth. The critical sub-catchments are prioritized based on PCSWMM by runoff results and CPM by considering WLPs, slope and impervious percentage of sub-catchments as input criteria. The inundation map results are validated with social media markers (SMMs). The outcomes from the simulation are found to be satisfactory and in agreement with the field water logging points (WLPs). The model simulation is performed for a 264 h (11 days) rainfall event that occurred in October 2020. In addition, the system resilience is examined by integrating PCSWMM with GIS. ![]() The present study investigates flood inundation in Hyderabad urban setting (zone-XII, zone-IV&V) using the Personal Computer Storm Water Management Model (PCSWMM) and prioritizes the critical sub-catchments using the compromise programming method (CPM) and PCSWMM. Thus, for effective planning and mitigation strategies, it is of paramount interest to quantify the generated runoff and prioritize the urban critical sub-catchments. Due to the dual pressure of rapid urbanization and climate change, urban flooding has become more common.
