In April / May 2018, a first extended field survey within the Mekong River, near the city of Vinh Long, was conducted by the Ludwig-Franzius-Institute (LuFI). During the in-situ campaign, the local bathymetry as well as several hydrological and sedimentological parameters were acquired for this year’s low-discharge season. The bathymetry was measured via multibeam echosounder, while an ADCP and LISST-probe were used to measure current velocities, respectively the grain sizes of sediments within the water column. Furthermore, a bedload sampler was used to get information about the bedload transport at hand.
A second field campaign is scheduled for autumn 2018, in order to acquire datasets for this year’s high discharge season.
