Abstract:
Bathymetric surveys were conducted within the Vietnamese Mekong Delta in April/May 2018 and September/October 2018 during the dry and wet season, respectively. The study area was focused on a 20 km stretch of the Tien River branch, located between the city of Sa Dec and the bifurcation spot of the Tien River with the Co Chien River near Vinh Long. Processed bathymetric data was interpolated onto a grid with a resolution of 1 x 1 m, while the Earth Gravitational Model 2008 was used as vertical reference system. The bathymetric maps were used to estimate annual sand mining activity and bed load transport rates within the study area. For more details on the processing of the data, see the corresponding paper and supplementary information.
