Population explosion, over-exploitation of natural resources, urbanization, etc., create disruptions in the natural environment leading to climate change, high-intensity-short-duration rainfalls, and natural disasters such as landslides, floods, and earthquakes. Flood is the most catastrophic among these. The extent of damages caused is even more tremendous if it occurs in an urban area. Though human interventions cannot strictly prevent the occurrence of floods, accurate flood forecasting with a sufficient lead time and proper flood management can reduce the possible damage to life and property. High demand exists for an experimental study incorporating a pluvial-fluvial flood event, as the same is the primary triggering factor for urban floods in India. Flood impact on buildings and the flood flow evolution around the urban structures is another topic that has gained attention recently. Though numerical models are available for urban flood simulations and analysis, the lack of real-time data for their validation questions their reliability. Hence, our research is driven by the need to develop a better understanding of urban flood dynamics, flow interaction between surface and drainage networks, flood impact on buildings, as well as the lack of reliable data required for the validation of existing numerical urban flood simulation models. We shall be assessing the flow, velocity, inundation pattern, forces imposed on urban infrastructure, and flow interactions (river-floodplain and surface-sewer) induced by a fluvial-cum-pluvial flood event over an urban area in the floodplain using experimental studies under steady and unsteady flow scenarios. An experimental study with such a complex setup will give a pragmatic view of real-world flood scenarios. Data generated from the research will serve as a good repository of benchmark standards for validating various urban flood simulation models. Comprehensive knowledge of flood flow dynamics within an urban setup aid in flood forecasting, damage mitigation, and flood control projects.
