This thesis examines flood monitoring and mapping in Kamrup District, Assam using Sentinel-1 SAR data. The objectives are to determine the best quality data for flood risk analysis. The study area experienced heavy rainfall and flooding in June 2022. The methodology involves preprocessing Sentinel-1 images from before, during, and after the flood, and analyzing additional data sources such as DEM, rainfall, NDWI, and land cover to map the flooded areas. The results show that Sentinel-1 SAR data has potential for rapid flood mapping.
