Vietnam – controlled seasonal flooding
The Mekong delta is to a large extent located in Vietnam. Flood water flows down from the Mekong river basin and drains into the Gulf of Thailand and into the South China or East Sea via a number of distributaries. The Mekong’s Sino-Vietnamese name, Cuu Long, translates as ‘nine dragons’, referring to the Mekong’s nine historical branches conveying its water. A ‘tenth dragon’, however, can also be identified and consists of sediment-laden flood water overflowing embankments during flood season. While in large parts of the delta this dynamic is prevented or reduced due to embankment construction, policy plans stress the relevance of and push to restore this form of controlled flooding in the upper regions of the delta.
