List of rivers of Bangladesh
Bangladesh is a riverine country. According to Bangladesh Water development board about 230 rivers currently flow in Bangladesh, although the number stated are ambiguous in some sources. As stated by a publication called বাংলাদেশের নদ-নদী by BWDB, 310 rivers flow in the summer although they republished another study in 6 volumes where stated 405 rivers. The number differs widely due to lack of research on the counts and the fact that these rivers changes flow in time and season.Old sources and history states about 700 to 800 rivers but most of them dried out or extincted due to lack of attention and pollution. The numbers differ also because same river changes name in different regions and in history. About 17 rivers are on the verge of extinction and the 54 rivers flow directly from India and 3 from Myanmar. Total of 57 international rivers flow through Bangladesh. The international number of rivers can be 58 as Brahmaputra is called "Nod" while the general term for river is "Nodi". The gender division of rivers is interesting from history and mainly depending on the source of the river but not the size or flow briskness.Sangu and Halda are the only two internal rivers originated and finished within Bangladesh. Surma is the longest river and Karnafuli is the swiftest.Jamuna is the widest river. According to banglapedia 700 rivers flow in Bangladesh, but the information is old and obsolete.There is an including tributaries flow through the country constituting a waterway of total length around. But the number differs ambiguously due to the lack of updated information.Most of the country's land is formed through silt brought by the rivers. Bangladesh geography and culture is influenced by the riverine delta system. Bangladesh lies in the biggest river delta of the world - the Ganges Delta system.

Ganges-Brahmaputra Delta
Bogra District
There are quite a few rivers in the district of Bogura. Taking the Karatoya as the central dividing water-channel of the district, the other rivers may be classified into the eastern and the Western systems. The course of all the rivers is, with such allowances as must be made for beds and windings, nearly uniform north and south. The eastern rivers are Monas, Charkadaha and Khamati besides a few other smaller ones. Through the khiar tracts in the western parts of the district flow the Nagar, the Tulshiganga, Nagar and other minor streams. All the western rivers are the tributaries of the Atrai which itself flows into the Jamuna north of the confluence of that river with the Ganges at Goalunda.Evidences show that the rivers Karatoya and Nagar have changed their courses in the past, while the Jamuna, lying on the eastern boundary of the district, is in fact a new channel of the Brahmaputra. A very small river, Tarai used to occupy more or
less the present location of the Jamuna. At that time the Brahmaputra used to flow to the east round the foot of the Garo Hills. The earliest evidence of the Brahmaputra river consists of a group of large Brahmaputra-size river scars which extend into the Sylhet basin flanking the southern edge of the Shillong plateau. The main river apparently extended east beyond this locality and then swung south into the Bay of Bengal. By the time of Rennell's mapping, this course had been abandoned in favour of a shorter route down what is still called the old Brahmaputra river past Mymensingh.
By the early 1770s the major diversion of the Brahmaputra into its present channel, west of the Madhupur jungle, had occurred. There is no complete agreement as to when this diversion down the Jenai river of Rennell occurred. Apparently by 1830 the diversion of low-river flow down the new channel was complete.

Noakhali District
In sharp contrast with the mainland to its south, there is a network of khals in the islands. As one advances from the older formation of chars towards the newer ones, the number of khals gradually increases. The khals gradually silt up, but where diluvion goes on, new khals come into existence and the old ones become wider and wider.

Pabna District
The general trend of the drainage of the Serajganj subdivision is from north-west to south-east, the rivers entering it from the north-west flow into the Jamuna after a tortuous course. In the Sadar subdivision, however, the general slope of the country is from west to east, and the main rivers fall into the Hurasagar, a tributary of the Jamuna.

Rajshahi District
during the rainy season. During the rainy season these moribund rivers act as excellent drainage channels draining off
a large volume of water and have a considerable current. Most of these rivers are narrow and flow in well-defined channels.

Tangail District
Among other important rivers of the district, Lohajang is worth mentioning. It flows past the district headquarters of Tangail and is almost dead at present. Other rivers are Khiru, Nanglai, Atia, and Jhinai. The old Brahmaputra's most important offshoot is the Jhinai; striking off near Jamalpur it rejoins the Jamuna north of Sarishabari, while another branch flows past Gopalpur. Now these sub-systems of rivers, viz, Bangshi and Banar, and the Lohajang, Khiru, Nangtai, Atia and Jhinai are all dying out because of the shift of the old Brahmaputra river from its former channel to the present Jamuna channel.
The most important question in connection with the river system of Tangail vis-a-vis Mymensingh district is when and why the Brahmaputra River changed its main old channel. During the last 150 years or so, this diversion of the old Brahmaputra to its present Jamuna channel has considerably prompted the geographers and geologists to enquire deep into it. Two theories are advanced: As explanation of the diversion, one theory describes the gradual uplift of the Madhupur Tract and a final trigger action of the Teesta diversion in 1787 as the chief factor; and the other theory states that the Brahmaputra diversion resulted directly from a major increase in its volume of water due to beheading of the Tsangpo river of Tibet by Dihang, a tributary of the then small Brahmaputral. It has now been proved that the great Tibetan river Tsangpo joined the Brahmaputra about 1780 and this accession was more important than the Teesta floods in deciding the Brahmaputra to try a shorter way to the sea.
With the help of Major James Rennell's maps and of the Revenue Survey it is possible to reconstruct the history of the Bengal Delta and its river systems. It was Rennell who carried out the first ever accurate cadastral surveys and laid the basis for the geographical study of Bengal. At the end of the 18th century, probably as a result of the great Tista floods in 1787, the Brahmaputra changed its course and joined the Padma at Goulundo. No piece-meal study of an intricate river system is possible, without distortion and inadequacy.
Even though we assume that the change in the course of the main waters of the old Brahmaputra took place suddenly in 1787, the year of the famous flooding of the Teesta river, the Teesta has been always a wandering river, sometimes joining the Ganges, sometimes being shifted outwards by the superior strength of the river Ganges and forced to join the Brahmaputra at last.
Whatever might have been the cause, by 1830, the diversion of old Brahmaputra was complete, ushering in a gradual but radical change in the river system of the Tangail district. The old channel of the Brahmaputra had been reduced to its present insignificance.
In 1850 Sir Joseph Hooker wrote "we are surprised to hear that within the last 20 years the main channel of Brahmaputra had shifted its course westwards, its eastern channel silted up so rapidly that the Jamuna eventually became the principal stream.
