Drought, Sulphate Acidifications & Saline Intrusion in Mekong Delta, Caused by the Hydro-Electric Dams in Upstream of River, and Climate Change | Book Publisher International

The hydropower dams (China, Laos, Thailand), primarily in China, are the main drivers of drought, pollution, and saltwater intrusion in the Mekong Delta, Vietnam. The water they obstruct amounts for more than 65 percent of the Mekong River basin's overall water resources. The Mekong's primary channel travels downstream, causing the river to dry up, causing traffic problems, a shortage of water to cultivate rice crops, and a lack of water for people's survival, especially during the dry season. However, a scarcity of water has resulted in significant damage: Acidification and salinization of sulphate become extremely high. Because, young, this is the Wetland. There are three layers on the soil horizon: 0-20cm: New alluvium; 20-50cm: Jarosite layer: Fe, Al double sulphate sediments; 50-150cm: Pyrite with a high S concentration (>5%); Floor 50-150cm: Pyrite with a high S concentration (>5%). Drought will exacerbate the acidification process. Drought, on the other hand, causes tidal infiltration to a depth of 70-100km, resulting in salinization; plants cannot withstand salt concentrations of less than 4g/L. The Mekong Delta has been severely harmed.
