Phung Tien Dung, head of the National Centre for Hydro-Meteorology Forecasting’s Hydro-Meteorology Forecasting Division for the Central, Central Highlands and South regions, said the delta would face the highest level of saltwater via the Mekong River in February and March.

The Vam Co and Cai Lon rivers, which are the major rivers in the delta, are expected to face the highest level of saltwater waves in March and April, he said.

Saltwater intrusion in the delta, which depends on the water level from the upper areas of the Mekong River and high tides, will see changes in the future.

“Localities in the southern region should keep up-to-date information about hydro-meteorology forecasts and have measures to prevent and control saltwater intrusion,” he said.

There will be little rain in the upper areas of the Mekong River and the Southern region on January 6 – 11, according to the Hydro-Meteorology Forecasting Division.
