| Abstract: | Most of the countries around the North Indian Ocean are threatened by storm surges associated with severe tropical cyclones.
The destruction due to the storm surge flooding is a serious concern along the coastal regions of India, Bangladesh, Myanmar,
Pakistan, Sri Lanka, and Oman. Storm surges cause heavy loss of lives and property damage to the coastal structures and losses
of agriculture which lead to annual economic losses in these countries. About 300,000 lives were lost in one of the most severe
cyclones that hit Bangladesh (then East Pakistan) in November 1970. The Andhra Cyclone devastated part of the eastern coast
of India, killing about 10,000 persons in November 1977. More recently, the Chittagong cyclone of April 1991 killed 140,000
people in Bangladesh, and the Orissa coast of India was struck by a severe cyclonic storm in October 1999, killing more than
15,000 people besides enormous loss to the property in the region. These and most of the world’s greatest natural disasters
associated with the tropical cyclones have been directly attributed to storm surges. The main objective of this article is
to highlight the recent developments in storm surge prediction in the Bay of Bengal and the Arabian Sea. |
