Indian State Release Flood Atlas With Satellite Imagery

The state of Odisha has created a flood hazard-based atlas, using historical flood inundation rates as its basis, measured via satellite imagery during 2001-2018. This will allow other Indian states to manage flood situations efficiently. The NRSC of ISRO had taken up the study based on current flood hazard-based zonation for State of Odisha. CM Patnaik launched the atlas at a State- level NCM meet on Saturday. Many areas in Odisha get inundated during flooding season in bigger rivers like Rushikulya, Subarnarekha, Baitarani, Brahmani, and Mahanadi. Budhabalanga and Vamsadhara cause floods as well.

As per Bishnupada Sethi of OSDMA, the damages are mostly caused by Baitarani, Brahmani and Mahanadi rivers. These have common deltas where waters intermingle. Here, considerable havoc is wreaked. The coastal regions are also inclined to storm issues, accompany by rainfall, making the region exposed to river flooding and storm surges. Few regions in South and West Odisha have flooding issues. As per NRSC, 8.96% land in the state was flood-affected between 2001 and 2018. 281,000 hectares were inundated as much as 14 times and were in high-risk categories.

8/30   like Cuttack, Khordha, Jajpur, Puri, Balasore, Jagatsinghapur, Kendrapara and Bhadrak are among the worst flood-affected areas. 70% and 77% of Kendrapara and Bhadrak respectively have categorization under flood hazard regions. As per PG Diwakar of ISRO, many satellite images were used to arrive at this number. Each inundation layer corresponds to around a year and represents flooding during that year.

Such layers were all assembled for over 18 years and then integrated into a flood hazard single layer that represented regions with flood inundation that had different frequencies. Digital databases were integrated to provide accuracy to the atlas and its layers. Chief Secretary AP Padhi stated that civil society members, policy makers, and planners would find this to be a valuable resource. This atlas will be of great importance to those trying to predict flooding destruction and base evacuation efforts upon them.
