Unique Flood Hazard Atlas: Odisha

Odisha has come out with a unique flood hazard atlas aided by satellite imagery, which is expected to help the coastal state manage floods more efficiently. The atlas was released by Odisha Chief Minister Naveen Patnaik at the State-level Natural Calamity Meeting.

About Flood Hazard Atlas

Need: Atlas would serve as a useful resource of information for policy makers, planners and civil society groups.

Base Period: Atlas is compiled on basis of historic flood inundation captured via satellite imagery over 18 years period from year 2001 to 2018.

Methodology:

Firstly, all satellite data sets were analysed and flood layers were extracted from it, then all flood layers corresponding to a particular year were combined into one inundation layer, so that this layer represents maximum flooded area in 1 year period.

Then all such combined flood layers for a period of 18 years were integrated into flood hazard layer representing observed flood-inundated areas with different frequencies. This layer was integrated with digital database layers of Odisha.

Key Findings of Study

The National Remote Sensing Centre (NRSC) of Indian Space Research Organisation (ISRO), Hyderabad had undertaken a study on Odisha’s flood hazard zonation.

Floods in Odisha: Every year vast areas of Odisha are inundated when there is flooding in major rivers of state, viz. Mahanadi, Subarnarekha, Brahmani, Rushikulya and Baitarani. Also, as per Odisha State Disaster Management Authority (OSDMA), damages due to floods are mainly caused by Mahanadi, Brahmani and Baitarani, which have a common delta where floodwaters intermingle and when in series simultaneously cause havoc.

Flash Floods: Few districts in western and southern part of Odisha are prone to flash floods which are caused due to instant run-off from hilly catchments areas of rivers like, Vamsadhara and Budhabalanga.

Hazard Prone: The entire coastal belt is prone to storm surges, which is commonly accompanied by heavy rainfall which then makes estuary region vulnerable to both storm surges and river flooding. Few districts in Odisha’s western and southern part of are prone to flash floods.

Hazard Categories: As per NRSC analysis during 2001-2018, about 8.96% (13.96 lakh hectares) of land in Odisha was affected by floods. Out of this 13.96 lakh hectare flood-affected area nearly 2.81 lakh hectares of land falls under high inundated flood hazard categories (7-9 times) to very high inundated flood hazard categories (10-14 times).

OSDMA bags SKOCH Award

The Odisha State Disaster Management Authority (OSDMA) has bagged the SKOCH Award, 2018 for its remarkable achievements in the field of disaster management. The award was presented at the 56th SKOTCH Summit held at New Delhi.

The SKOCH Award is being presented since 2003 to individuals and institutions having done meritorious works in the field of governance, finance, banking, disaster management, technology, corporate citizenship, economics and inclusive growth by Skoch Group.

OSDMA and Disaster Management

  • OSDMA had received Order-of-merit in the Gold category for constructing 879 multipurpose cyclone and flood shelters which played a key role in saving human lives during Cyclone Phailin in 2013.
  • OSDMA had received ‘Order-of-merit’ in the silver category for constructing disaster resilient houses for about 17,000 Phailin affected families by relocating them to safer places.
  • Order-of-merit Bronze was given to the OSDMA for its Early Warning Dissemination System for different hydro-meteorological disasters across the coastline of Odisha which will benefit 1,205 villages in 22 blocks of six coastal districts.
  • OSDMA had received ICHL award, 2013 for Excellence in Humanitarian Action in the field of Disaster Management and many certifications for effective management of disasters.

These awards are the recognition of Odisha becoming a model state in disaster management and risk mitigation since the 1999 Super Cyclone.
