    Jamuna river in Bangladesh

    The former name is Jonai River, Jamuna is one of the three major rivers of Bangladesh but in the past, it was originally a canal (Jonai Canal) which is now huge. In the flood of 1787, the Brahmaputra flowed into a new stream and created this river. The Jamuna River flows into the Padma River at Goalanda (along with the Brahmaputra). Hall Teesta, Dharla, Karatoya, Atrai, Subarnashree (longest and largest tributary of Karatoya Jamuna) Bengali + Jamuna Bogra. The only international river in Bangladesh is the Padma and the main river of the delta is the Padma, which joins the river Jamuna at Goaland (Rajbari). The Jamuna river system is the widest north-south river system in the country. The flow of the Brahmaputra-Jamuna is recorded at Bahadurabad. The Brahmaputra-Jamuna has four main tributaries: the Dudhkumar, the Dharla, the Teesta and the Karatoya-Atrai. Of these, the Dudhkumar, Dharla, and Teesta rivers are three fast-flowing stresms and originate from the steeply sloping basin in the southern part of the Himalayas between Darjeeling and Bhutan in India. The oldest Brahmaputra is the longest of the tributaries and this was the main course of the Brahmaputra two hundred years ago. 


    Some features of Jamuna 

    The Brahmaputra originates from the Chemayung-dung Glacier (31 degree 30 N and 80 degree 20 E), 145 km from parka, an important trading center between Manas Sarovar and Mount Kailash in Tibet. The Brahmaputra river in Assam was called Dihang before it fell into the vast plains of Bengal. It entered Bangladesh through the Kurigram district. The combined length of the Sangpo-Brahmaputra-Jamuna is about 2,700 km east of the confluence with the Ganges. The length of the Brahmaputra-Jamuna in Bangladesh is 276 km of which the length of the river Jamuna is 205 km. The earthquake caused the Jamuna River and among the rivers of Bangladesh, the highest number of chars is in our Jamuna. In the month of August, extensive floods often occur. Floods from may to July occur due to increased flow in the Brahmaputra-Jamuna and Meghna rivers. The Brahmaputra-Jamuna flows faster than the Ganges. The average slope of the Jamuna is 1:11,850, slightly higher than the Ganges slope. The Jamuna also carries a large amount of sediment along with a large body of water. During the monsoon season, the Jamuna river carries about 12 lakh tonnes of silt daily and the annual sediment carrying capacity of the Jamuna measured at Bahadurabad is about 735 million tonnes. Besides, two colored streams of water are found in this river. The transition or change of major river channels in Bangladesh can take place between 60 meters to 1600 meters per year. The Jamuna is one of the major erosions that can occur along a coastline of about 2400 km in a particular year. Jamuna River The Jamuna is a braid-shaped river whose bank elements are very sensitive to erosion. Although many currents come together side by side, the Jamuna never flows in a single stream. Instead, many small currents merge into a cluster and move hand in hand. A 4.8 km long bridge has been recently built over the Jamuna River to connect the eastern and western parts of Bangladesh divided by the river Jamuna. Named as Bangabandhu Jamuna Multipurpose Bridge, the eastern end of the bridge is located in Bhuapur Upazila of Tangail district and the western end in Sirajganj Sadar Upazila of Sirajganj district.  In addition to the rapid transport of passengers and goods on the existing roads and railways, the transmission of electricity and natural gas though the bridge and telecommunication has been accelerated. The bridge was opened to traffic on June 23, 1998. Extensive river management activities were carried out to keep the highly flowing river Jamuna flowing in the sector determined by the bridge.
