"The Bay of Bengal -- Coastal Management Problems and Prospects"
Junaid As-Salek
NRC Research Associate

Tuesday, April 11, 2000
10:00-11:00 a.m.

Four problems related to coastal management in the Bay of Bengal will be
discussed:

1) Owing to the inaccurate prediction of the arrival time and
characteristics of cyclones and storm surges, about 400,000 and 140,000
people respectively died in the 1970 and the 1991 cyclones on the Bay of
Bengal. In fact, storm surges resulting from cyclones frequently visit
Bangladesh, kill hundreds of people and cause heavy damages.
2) Having a vast area of 0.0 m to 1.0 m elevation, Bangladesh is very much
susceptible to sea level rises. P. Bruun (1992) estimated that a 1.0 m rise
of sea level would inundate 10 percent of total area of Bangladesh. Global
warming will intensify the power of cyclones, and storm surges are expected
to appear with higher peaks.
3) In Bangladesh, arsenic contamination of the ground water extracted
through tube wells for drinking purposes is a major concern. The flora and
fauna of the Bay of Bengal may consume a portion of the arsenic. The
colloidal sediment carried by the rivers may be a major conveyor of the
arsenic from the sources.
4) The Meghna estuary is one of the largest sediment conveying estuaries in
the world. Management of sediment to build new lands in the vast and
shallow coastal zones could be a solution to that highly populated country
