The water level of the Mekong River is expected to rise to its highest in four years due to the combined effect of floods and high tide, entailing a high risk of serious inundation in low-lying areas in Vietnam’s Mekong Delta.
The water level in the headwaters of the Mekong River is increasing due to rising tide, the National Center for Hydro-meteorological Forecasting stated.
The water level is expected to continue rising in the coming days and may reach its highest over the past four years due to the combined influence of floods and high tide.
Between October 10 and 13, the water level of the Tien (Front) River measured at Tan Chau Station in An Giang Province is likely to reach 3.7 meters, about 0.9 meters higher than the peak level in 2021.
The water level of the Hau (Back) River measured at Chau Doc Station in An Giang Province will hit 3.3 meters, about 0.7 meters higher than the peak in 2021.
The situation will pose a high risk of inundation in low-lying areas in An Giang, Dong Thap, and Long An Provinces in the Mekong Delta.
The National Center for Hydro-meteorological Forecasting added that rainfall in the delta in the final months of 2022 will be higher than the average of previous years.
Unseasonal rains will likely fall in southern Vietnam at the beginning of next year’s dry season.
Saltwater intrusion in the Mekong Delta will be similar to or less severe than that in last year’s dry season.
