North Mekong Delta

The northern mouths of the Mekong open onto a low coast shaped by river sediment, waves and tides. The Tiền River, one of the great branches of the Mekong, divides again into channels including the Cửa Tiểu, Cửa Đại and Hàm Luông. Mudflats and mangroves fringe their mouths. During the wet season, the swollen river carries sediment seaward; in the drier season, northeasterly winds drive waves along the coast.
