High-frequency turbulence and suspended sediment concentration measurements in the Garonne River tidal bore
The study details new sediment concentration measurements associated with some turbulence characterisation conducted at high-frequency in the undular tidal bore of the Garonne River (France). Acoustic Doppler velocimetry was used, and the suspended sediment concentration was deduced from the acoustic backscatter intensity. The field data set demonstrated some unique flow features of the tidal b...
متن کاملMeasuring Suspended Sediment and Its Wave and Turbulence Forcing in the Dee Estuary
Coastal areas support many human activities and represent a very important habitat for many marine and bird species. The Dee estuary, located in the eastern Irish Sea, is 20 km long, 8 km wide at the mouth and is characterized by a 10 m tidal range. Suspended and seabed sediments in the Dee contain a diverse assemblage of non-cohesive and cohesive sediments, and therefore the threshold of motio...
متن کاملTidally induced turbulence and suspended sediment
[1] Nearly continuous data collected using novel methods are utilized to advance the understanding of turbulence and suspended particulate matter (SPM) dynamics under strong tidal flow conditions. Key instrumentation includes a single acoustic current profiler that provides nearly continuous, concurrent turbulence and SPM information with respect to depth near the seafloor and within the water ...
متن کاملAn analytical model of the equilibrium distribution of suspended sediment in an estuary
An analytical solution of the equilibrium distribution of suspended sediment concentrations (SSC) in an estuary along the longitudinal axis is extended to include variable width. A turbidity maximum is formed at the convergence of fluxes from freshwater discharge and (vertically well mixed) salinity gradients. Simple scaling relationships control the longitudinal distribution of SSC and depend ...
متن کاملTurbulence and Suspended Sediment Measurements in an Urban Environment during the Brisbane River Flood of January 2011
In urbanized areas, flood flows constitute a hazard to populations and infrastructure, as illustrated during major floods in 2011. During the 2011 Brisbane River flood, some turbulent velocity data were collected using acoustic Doppler velocimetry in an inundated street. The field deployment showed some unusual features of flood flow in the urban environment. That is, the water elevations and v...
