摘要
A field observation of the hydrodynamics and the sediment resuspension in a bottom boundary layer was carried out in the Changjiang Estuary, during July—August 1997. Using bottom field research facilities, detailed measurements of near-bottom currents and suspended sediment concentration distribution within 1.0 m above bed have been obtained in the Changjiang Estuary — a high concentration estuary. An Acoustic Suspended Sediment Monitor (ASSM) was used to observe near bed sediment resuspension processes. In addition, the log-profile method was applied to estimating hydraulic roughness z0 and bottom shear stress values (or friction velocities u*).
