Megna Mouth

At the mouth of the Meghna, the combined waters of the Ganges and Brahmaputra meet the tides of the Bay of Bengal. The estuary divides into great channels around islands including Bhola, Hatiya and Sandwip. River-borne sediment is deposited along their shores, while erosion removes land elsewhere. Monsoon floods and tidal currents continually reshape the channels between the islands and the mainland.
