📖 Introduction
Feni River Basin
The Feni River flows for approximately 135 km south of Agartala, the capital of Tripura. It is a significant transboundary river shared by India and Bangladesh.
The river's total catchment area is 1,147 square km. Of this, 535 square km lies within India, with the remaining portion in Bangladesh.
The Feni River plays a crucial role in forming a part of the Indo-Bangladesh border, delineating the international boundary in certain stretches.
The Maitri Setu, a 1.9 km long bridge, has been constructed over the Feni River in Tripura. This bridge serves as a vital link connecting India and Bangladesh, enhancing trade and connectivity.
- Notable tributaries of the Feni River include the Muhuri River, Raidak River, Chandkhira River, Ryang River, and Kushiyara River.
Kushiyara River Basin
The Kushiyara River is an important distributary of the Barak River. Its origin point is the Amlshid bifurcation point located on the India-Bangladesh border.
At the Amlshid bifurcation, the Barak River divides into two main streams: the Kushiyara River and the Surma River.
The Kushiyara River begins its journey in Assam, India, and collects water from various tributaries originating in Nagaland and Manipur before flowing into Bangladesh.
Brahmaputra River Basin
The Brahmaputra River is one of Asia's largest rivers, originating from the Chemayungdung glacier near Yarlung Tsangpo in Tibet, close to Mount Kailash.
It flows through Tibet, India, and Bangladesh, acting as a natural geographical feature between regions.
Within India, the Brahmaputra passes through Arunachal Pradesh, Assam, and Meghalaya. Upon entering Bangladesh, it is known as the Jamuna River.
- Major tributaries in India include the Subansiri, Kameng, Manas, and Dhansiri rivers.
- The Teesta River is a significant tributary that joins the Brahmaputra (Jamuna) in Bangladesh.
In Bangladesh, the Brahmaputra River (Jamuna) merges with the Ganga River, forming the combined stream known as the Padma River. The Padma then further merges with the Meghna River.
The combined waters of the Padma and Meghna rivers ultimately flow into the Bay of Bengal through the extensive Meghna Estuary, forming one of the world's largest deltas.
Meghna River Basin
The Meghna River system has a complex origin. In India, specifically in Karimganj district in Assam, the Barak River splits into two distinct streams: the Surma and the Kushiyara.
These two distributaries, the Surma and Kushiyara, later rejoin in Kishoreganj district in Bangladesh. From this confluence point, the combined river is known as the Meghna.
Up to Chandpur in Bangladesh, this river is referred to as the Upper Meghna. After meeting the Padma River at Chandpur, it becomes known as the Lower Meghna.
