Pollution of the Ganges sea ports located close to this dike. The proposed dike would be similar to the land reclamation of North Sea area called Delta Works in Netherlands. The experience of the Saemangeum Seawall already constructed in South Korea which is 33 km long and with 36 meters average depth, can be utilised for this project which is a lesser challenging project. Locks arrangement (similar to Panama canal) would be provided for the movement of ships from the open sea to harbours located in Bangladesh and India. The off shore earth dam extending up to +8 m msl height, is in the
Indus River Delta-Arabian Sea mangroves time it reaches the delta, the flow of freshwater is down by more than 90% compared to historic levels. Active flow only lasts for about two months, and the sediment load is similarly diminished. Saline water intrudes upstream for about and this affects both the mangroves growing in the area and the agricultural land. Loss of sediment causes increased coastal erosion, and this is exacerbated by land subsidence and rising sea levels. Other factors affecting the mangrove areas are pollution from sewage and industrial effluent, and parts of the mangrove area have been lost to agriculture and urban development. The
