Abstract

River water level variation monitoring on surface water resource management is crucial for socio-economical development and global warming. This research was performed in Mekong Delta Basin to access on the quality of satellite-derived water level using ENVISAT and Jason-2 datasets. The results show that water level accuracy is variable from 0.2 m in the best cases to 0.5 m in most cases. These accuracies are affected by some factors including river width, terrain, braided river as well as forest and settelement features around the intersection of the satellite track and water surface.
