SALTWATER INTRUSION RISK IN MAIN RIVERS OF VINH LONG PROVINCE IN THE CONTEXT OF CLIMATE CHANGE AND SEA LEVEL RISE

Abstract

The study aimed to assess the risk of salt water intrusion in VinhLong province in the context of climate change via following scenarios: 2014, 2020, 2030 with average (B2) and high (A1FI) level of greenhouse gas emission. By modeling (NAM, MIKE 11), combined with GIS, results showed that the highest salinity in 2014 was about 5‰ (in Co Chien River) and salinity in Tien River was higher than that in Hau River. Saltwater intrusion in Vinh Long province tends to increase with time and climate change scenarios. The highest salinity in 2030 would be up to 8‰ (in Co Chien River), affecting some communes of Vung Liem and Mang Thit district. This work provides an important basis for planning suitable solutions for saltwater intrusion adaptation, contributing to sustainable develoment goals of the local.
