A Retrospective Comparision Study of Remote Sensing Satellite Derived Tropical Cyclone Caused Flood Prone Areas Along Bay of Bengal Coastal Vicinity Districts of Andhra Pradesh

Floods are one of the most common and widespread disasters in India, with an estimated 40Mha of land prone to this natural disaster (National Flood Commission, India). Significant loss of property, infrastructure, livestock, public utilities resulting in large economic losses due to floods are recurrent every year in many parts of India. India encountered many cyclonic flood events during Oct-Dec 2013-2014, among which Phailin, Lehar, Madi and HudHud were rated to be very severe cyclonic storm. The path and intensity of these cyclonic events was very well captured by the model and areas were marked with persistent coverage of high runoff risk/flooded area. These thresholds were used to monitor floods in Jammu Kashmir during 4-5 Sep and Odisha during 8-9 Aug, 2014. The present study is to explore the usefulness of Remote sensing satellite derived surface runoff, to relate to the occurrence of flood inundation due to persistent and successive high surface runoff conditions. The study dealt with retrospective comparison of Flood caused due to tropical cyclone HudHud occurred on 12th Oct 2014 along Bay of Bengal coastal belt districts of Andhra Pradesh from NASA web tools and BHUVAN-ISRO web tools. Considering Bhuvan Geoportal for past flood records, not well defined as realistic conditions except at East Godavari district. Global Flood Monitoring System (GFMS) of NASA Web-Tool predicts the realistic flood scenarios during cyclonic storm of Hudhud on 12th October 2014.
