- The Coastal Embankment Project is one of the outstanding undertakings of East Pakistan Water and Power Development Authority. Passing through the districts of Khulna, Bakerganj, Noakhali and Chittagong and parts of Jessore, the coastal belt stretches over 330 miles along the Bay of Bengal. It extends from the Indian border on the west to Burma border on the east.
- With its peculiar geographical position being situated on the apex of the Bay of Bengal, East Pakistan witnesses very difficult climatic conditions and is frequently visited by cyclonic storms, tornadoes and tidal bores. The night of 12th Nov. 1970 in the coastal areas of East Pakistan was undoubtedly the worst in living memory. Most of the lands in the coastal areas of East Pakistan lie below the high-tide level and are, therefore, flooded if not protected by dykes and embankments. When the land is flooded by sea waters, it leaves a layer of soil on the ground and makes the land unfit for cultivation until the salt is leached down by rain water. When any area is enclosed by dykes, it becomes necessary to provide arrangements to drain out the accumulated rain water from within the embankment area. This drainage is governed by the tide levels in the rivers i.e. water will drain out as long as the level in the river remains below the land level. Most of the lands in these areas have been brought under cultivation by farmers who put up some sort of low dykes (bunds) along the banks of the rivers but not much could be done by them against the ravages of tidal bores and in-rush of sea-water.
- The East Pakistan Water and Power Development Authority has prepared the Coastal Embankment Project to provide for properly designed embankments which are strong enough to withstand the pressure of sea water and for sluices gates which will automatically drain out water from within the embanked areas. In preparing the project, the embankments have been aligned in such a manner that all major tidal rivers and routes of navigation have been kept open. The embankments have been designed to withstand normal tide levels and surges. These will be provided with flap gates on the river side which will open automatically when the tide level goes below the land level and will close when it is higher than the water level.
