VietNamNet Bridge – Every year, 55 million tons of sediment is lost from the rivers in Mekong Delta, 90 percent of which is sand.

The coastal provinces in the western part of the southern region are also directly affected by the change.

The alluvium from river mouths to the sea has the function of protecting the coast, easing the impact from waves hitting the coast. When there is not enough silt, the sea water will cause erosion. Tiếp tục đọc “Mekong Delta faces increased risk of landslides as sediment loss continues” →
