India to Map Its Costal Hazard Line to Enhance Prepared Sec- Based Hazards Like Tsunami-Like Event

 

 

 Stereo Digital Aerial Photography (SDAP) will be used to map the coastline of the country. The total cost involved for SDAP is Rs.27crores. The SDAP will cover the 11000km arc coastline from Gujarat to West Bengal with an area of 60,000sq kms. This initiative is a critical part towards the planned management of the country’s coastal zone. Under the World Bank assisted project, the hazard line for the mainland coast of India will be mapped, delineated and demarcated on the ground over a period of five years. This will include the collection and presentation of data, identifying flood lines over the last 40 years which includes sea level rise impacts, and a prediction of erosions to take place over the next 100 years. , 


The Ministry of Environment and Forests has signed an agreement with the Survey of India , Department of Science and Technology, to map, delineate and demarcate the hazard line along India’s wide coastal belt. The Memorandum of Understanding for this project was signed on 12th May, 2010. The hazard line is a composite line of the shoreline changes including sea level rise due to climate change, tides and waves. The total cost of this survey is projected at Rs.125 crore.

For the purpose of SDAP, the Indian mainland coastline has been divided into eight blocks, namely, (1) from the Indo-Pakistan border to Somnath in Gujarat; (2) Somnath to Ulhas River in Maharashtra; (3) Ulhas River to Sharavathi River in Karnataka; (4) Sharavathi River to Cape Comoran in Tamil Nadu; (5) Cape Comoran to Ponniyur River in Tamil Nadu; (6) Ponniyur River to Krishna River in Andhra Pradesh; (7) Krishna River to Chhatrapur in Orissa; and (8) Chhatrapur to Indo-Bangladesh Border in West Bengal.
