| SURGE PRONE COASTS OF INDIA|
Storm surge heights depend
on the intensity of the cyclone, i.e., very
high-pressure gradient and consequent very strong winds
and the topography of seabed near the point where a
cyclone crosses the coast. Sea level also rises due to
astronomical high tide. Elevation of the total sea level
increases when peak surge occurs at the time of high
Vulnerability to storm
surges is not uniform along Indian coasts. The following
segments of the east coast of India are most vulnerable
to high surges
i) North Orissa, and
West Bengal coasts.
ii) Andhra Pradesh
coast between Ongole and Machilipatnam.
iii) Tamil Nadu coast,
south of Nagapatnam.
The West coast of India is
less vulnerable to storm surges than the east coast of
India in terms of both the height of storm surge as well
as frequency of occurrence. However, the following
segments are vulnerable to significant surges :
i) Maharashtra coast,
north of Harnai and adjoining south Gujarat coast
and the coastal belt around the Gulf of Bombay.
ii) The coastal belt
around the Gulf of Kutch.
