Abstract: The Mekong Delta of Viet Nam has a total area of 3.9 million hectares, of which 2.4 million ha is agriculture land. The Mekong Delta is very flat and low, an average of the elevation is about 1 m above the mean sea level. It is considered as the main rice bowl of Viet Nam, it contributes 50%of the national food product and more than 90%of annual exported rice product. The Mekong Delta of Viet Nam is located at most downstream of the Mekong River and it is affected by annual flood, drought and salinity intrusion. In which, drought and salinity intrusion are considered as vital issues, these will be a threat to sustainable agriculture development of the Mekong Delta and food security of Viet Nam. Through analyzing the historical flow data at Kratie station from 1924 to 2012 the change of flow regime during the dry season and monthly discharge was discovered, this is also contribution to forecast the long-term dry season flow and salinity intrusion.
