Abstract: Along the coastline of 3260 km in Vietnam, from Mong Cai in the north to Ha Tien in the south, there are more than 130 estuaries and two fertile deltas known as the Red River Delta and the Mekong River Delta. On average, there is an estuary per every 25 km of coastline, extending through the territories of 24 provinces and cities, which include 127 urban and rural districts. Vietnam is in tropical monsoon climate regime, coastal area is affected by natural calamities as typhoon, monsoons, storm surge, sea level rise and El-Nino phenomena. Therefore, interaction processes between the land and sea, between rivers and sea and between human and nature are very strong. Due to the differences in river basins, geology, meteorology and tidal conditions, estuaries in Vietnam can be classified into different types, in which each has its own characteristics. This paper reviews the existing estuary research and waterway engineering in several typical estuaries such as Ba Lat, Thuan An and Dinh An estuaries. The characteristics of morphological evolution, tide, current, wave and sediment transport as well as the impact of human activities and manmade structures on the estuarine morphology are presented.
