This study estimated the time series of surface water area by processing Landsat images from the Google Earth Engine platform. Then, the area – volume – elevation relationship constructed from DEM was used to derived the water level and volume from the surface water area datasets. The results showed that remote sensing enables to monitor temporal variations of water level and volume of reservoirs. Remote sensing can also detect the wet and dry periods and determine the operation of reservoirs, which supports to improve inflow prediction to Vietnam, and therefore, improve the water resources management in the transboundary rivers. |
