Brahmaputra River, Ganges River, surma River, Atrai River, Teesta River.
The Brahmaputra River is one of the greatest in Asia and the longest to pass through Bangladesh, covering a length of 1,802 miles, and also cutting across India, Bhutan, and China. It starts from Kailash in northern Tibet and ends in the Bay of Bengal. The Assam people see this river as both a blessing and a curse citing the floods it causes on the adjacent land during the monsoon but leaves an immensely fertile ground after the floods. Peasants take advantage of this land not only to plant food for their use but also for export purposes.
