The Jamuna River is second largest of the three main rivers in Bangladesh. It is the
main distributary channel of the Brahmaputra River as it flows from India to Bangladesh. Actually Jamuna is the downstream course of the Brahmaputra River. The Brahmaputra-Jamuna is one of the largest river in the world, with its basin covering areas in Tibet, China, India and Bangladesh. The Jamuna flows south and joins the Padma river, near Goalundo ghat, before meeting the Meghna river near Chandpur and then flows into the Bay of Bengal as the Meghna river.
The Jamuna is a very wide river. During the rains it is about 5–8 miles (8.0–13 km) from bank to bank. Even during the dry season when the waters subside, the breadth is hardly less than 2–3 miles (3.2–4.8 km).
