The 'Jamuna River is one of the three main rivers of Bangladesh. It is the main distributary channel of the Brahmaputra River as it it flows out of India into Bangladesh. The Jamuna flows south and joins the Padma River (Pôdda) near Goalundo Ghat. Merged with the Padma, it meets the Meghna River near Chandpur. Its waters then flow into the Bay of Bengal as the Meghna River.
The Brahmaputra-Jamuna is a classic example of a braided river and is highly susceptible to channel migration and avulsion.
The Jamuna was a barrier in establishing a direct road link between capital Dhaka and northern part of Bangladesh better known as Rajshahi Division until 1996. This was mitigated by the completion of the Jamuna Multi-Purpose Bridge.
The Jamuna is a braided stream characterised by a network of interlacing channels with numerous sandbars enclosed in between them. The sandbars, known in the Bengali as chars do not, however, occupy a permanent position. The river deposits them in one year very often to destroy and redeposit them in the next rainy season. The process of deposition erosion and redeposition has been going on continuously making it difficult to precisely demarcate the boundary between the district of Pabna on one side and the district of Mymensingh Tangail and Dhaka on the other. Breaking of a char or the emergence of a new one is also a cause of much violence and litigation.
The Jamuna is a very wide river. During the rains it is about 5-8 miles from bank to bank. Even during the dry season when the waters subside, the breadth is hardly less than 2-3 miles.
The Jamuna is a very important waterway. It is navigable at all seasons of the year by large cargo and passenger steamers. Before Partition passenger steamers used to ply up to Dibrugarh in the State of AssaJn in Indian Union. At present two steamer ferry services interlink the district of Pabana with the districts of Mymensingh, Tangail and Dhaka. The Bangladesh Railway maintains a forry service between Serajganj in Pabna and Jagannathganj in Mymensingh. The other ferry service between Nagarbari in Pabna and Aricha in Dhaka is run by the C & B Department.
