Flood is natural hazards that affect the human lifestyle and their physical properties .due to climate change, a flood is often typical in the urban region or near the river bank. The urban flood is an excellent example of climate change; also, this flood affects other activities such as transportation. Various remote sensing satellite data sources have been used to monitor, map, and model the urban flood, such as LANDSATs series data , IRS , Sentinel-2 & 1. However, 3D based visualizing and mapping is still not given much attention like 2D based modelling. Therefore, it is necessary to visualize an urban flood using 3D InSAR. InSAR is Interferometric SAR data that helped to make 3D. This study is carried out in the Koshi river of the region in Bihar, which focuses on providing evidence of 3D based monitoring of urban flood impact in the study region. Sentinel-1 satellite also provides InSAR remote sensing, which is used to create a 3D building in the study region and overlayed with Sentinel-1 (A&B) flooded urban areas before and after the event. This study has analyzed the changes in urban areas due to floods and estimated impact
