The Red River Delta (Vietnamese: Đồng Bằng Sông Hồng) is the flat plain formed by the Red River and its distributaries joining in the Thai Binh River in northern Vietnam. The delta measuring some 15,000 square km is well protected by a network of dykes. It is an agriculturally rich area and densely populated. Most of the land is devoted to rice cultivation[1].
Nine provinces together with two municipalities, the capital Hanoi and the main port Haiphong form the delta.
