Surma-Meghna River System

Near its source, the river receives a number of tributaries, including the Irang, Makru, Tuivai, Jiri, Gumti, Howrah, Kagni, Senai Buri, Hari Mangal, Kakrai, Kurulia, Balujhuri, Shonaichhari and Durduria.

The principal tributaries of the Barak in India are the Irang, Makru, Tuivai, Jiri, the Dhaleshwari (Tlawng), the Singla, the Longai, the Madhura, the Sonai (Tuirial), the Rukni and the Katakhal.

The Meghna is formed inside Bangladesh above Bhairab Bazar by the combination of the Surma and Kushiyara rivers.

After Chandpur, with the combined flow of the Padma and Jamuna, it moves down to the Bay of Bengal in an almost straight line.

Near Bhola, just before flowing into the Bay of Bengal, the river divides into two main streams in the Ganges delta and separates an island from both sides of the mainland.
