Buriganga River

The Buriganga River(Bu?igônga "Old Ganges") is the main river flowing beside Dhaka city, capital of Bangladesh.
In the distant past, a course of the Ganges river used to reach the Bay of Bengal through the Dhaleshwari river. This course gradually shifted and ultimately lost its link with the main channel of the Ganges and was renamed as the Buriganga. It is said that the water levels during high and low tides in this river astonished the Mughals.The water tables even is very astonishing due to pollution of polythenes deposited beneath water. The materials from breaking of buildings of the river banks also add hazardous substances in the river.
The Buriganga is economically very important to Dhaka. Launches and Country Boats provide connection to the other parts of Bangladesh, a largely riverine country. Due to siltation, large steamers can no longer go through the river channel in the dry season. In 1989, a bridge (the Bangladesh-China Friendship Bridge) was built over the river for vehicles and pedestrians. In 2001, a second bridge over the river was built at Babubazar for vehicles and pedestrians.
