Catch-Mekong

ADCP buoy operational on the Mekong

GFZ developed a river buoy equipped for constant monitoring of velocity profiles and suspended sediment concentrations by a downward looking ADCP. The buoy was shipped to Vietnam and moored next to the hydrographic monitoring vessel at My Thuan bridge near Vinh Long in the Mekong (Tien) river beginning of March. It operates autonomously and records the data at 15 minute intervals. The data are automatically transferred to GFZ for storing and processing. The aim of the buoy is to test its capability of permanent flow velocity, discharge, and suspended sediment monitoring in comparison to the operational manual monitoring. If successful, the buoy could provide a low cost addition to the manned monitoring sites at other location in the Mekong Delta.
