Jamuna River (Bangladesh)

The Jamuna is the lower stream of the Brahmaputra River, which originates in Tibet as Yarlung Tsangpo, before flowing through India and then southwest into Bangladesh.

The Brahmaputra-Jamuna is a classic example of a braided river and is highly susceptible to channel migration and avulsion.

The confluence of the Jamuna and the Padma rivers is unusually unstable and has been shown to have migrated southeast by over fourteen kilometres between 1972 and 2014.

[3] In Bangladesh, the Brahmaputra is joined by the Teesta River (or Tista), which is one of its largest tributaries.

In these maps, Teesta is shown as flowing through North Bengal in several branches — Punarbhaba, Atrai, Karatoya, etc.

[7] The main channel of the Brahmaputra at Bhahadurabad point was switched southwards and opened as Jamuna due to the result of caused tectonic uplift of the Madhupur tract.

The Jamuna was a barrier in establishing a direct road link between the capital Dhaka and northern part of Bangladesh, better known as Rajshahi Division, until 1996.

Before the Partition of Bengal in 1947, passenger steamers used to ply up to Dibrugarh in the state of Assam in the Indian Union.

James Rennell's 1776 map shows the Brahmaputra's main flow through Jamalpur and Mymensingh and a much narrower Jamuna or Jamuneswari before an earthquake in 1762, and the Teesta R. flowing in 3 channels to the Ganges before a flood in 1787.
