Abstract
The Mekong River is one of the world's great rivers. Comes from its source on the Tibetan Plateau in China to the Mekong Delta, the river flows through six countries: China, Myanmar, Thailand, Lao, Cambodia, and VietNam. Due to the climate change and the construction of hydropower dams along the Mekong River, the water resources in the downstream areas are increasingly depleted, seriously affecting the people's lives and productions. To minimize their impact, changes in water levels over time should be appropriately monitored. This study presents satellite altimeter data (Envisat, Jason-1/2/3, SARAL, and Sentinel-3A/3B) to monitor water levels in the Mekong River (Vietnam) from 2002 to 2022. The water level comparison results at virtual stations with data measured at hydrological stations show high accuracy with a correlation of 0.88 and an RMSE = 0.18m. The study results contribute to supplement data for areas with few hydrological/tide stations, especially effective in monitoring water outside the border of Vietnam.
