How do the Ganges and Brahmaputra rivers reach the Bay of Bengal?

The Ganges and Brahmaputra rivers reach the Bay of Bengal by converging in Bangladesh to form a massive, sediment-rich delta system.12

The process occurs as follows:
* Confluence: The Brahmaputra (known as the Jamuna in Bangladesh) and the Ganges (known as the Padma in Bangladesh) meet north of Goalundo Ghat.12
* Combined Flow: Their combined waters, referred to as the Padma, flow southeast until they reach a confluence with the Meghna River near Chandpur.12
* Final Discharge: The main body of the river enters the Bay of Bengal through the Meghna estuary and various smaller channels that branch off through the Ganges-Brahmaputra delta.12

This delta, which includes the Sundarbans mangrove forests, is shaped by tidal processes and carries one of the world's highest sediment loads.12
