Cross-shore suspended sediment transport under tidal currents
The transport of sediment over an intertidal mudflat by a cross-shore tidal current is investigated analytically by formulating a mathematical model of the fluid and particulate motion. The model exploits the low gradient of the intertidal flats and is based upon a shallow-layer approximation. It is found that the sediment transport comprises advection with the mean flow, deposition and erosion...
متن کاملSuspended sediment fluxes at an intertidal flat: The shifting influence of wave, wind, tidal, and freshwater forcing
Using in situ, continuous, high frequency (8–16Hz) measurements of velocity, suspended sediment concentration (SSC), and salinity, we investigate the factors affecting near-bed sediment flux during and after a meteorological event (cold front) on an intertidal flat in central San Francisco Bay. Hydrodynamic forcing occurs over many frequency bands including wind wave, ocean swell, seiching (500...

PAN, C. and HUANG, W., 2010. Numerical modeling of suspended sediment transport in Qiantang River: an estuary affected by tidal bore. Journal of Coastal Research, 26(6), 1123–1132. West Palm Beach (Florida), ISSN 0749-0208. Study of suspended sediment transport in an estuary affected by tidal bore is important for coastal engineering and management because the tidal bore can cause strong sedime...
متن کاملFormulating Fine to Medium Sand Erosion for Suspended Sediment Transport Models
The capacity of an advection/diffusion model to predict sand transport under varying wave and current conditions is evaluated. The horizontal sand transport rate is computed by vertical integration of the suspended sediment flux. A correction procedure for the near-bed concentration is proposed so that model results are independent of the vertical resolution. The method can thus be implemented ...
متن کاملRemote Sensing of Tidal Situation by Monitoring Changes in Suspended Sediment Concentration in Surface Waters
Collecting information on suspended sediments concentration (SSC) in coastal waters and estuaries is vital for proper management of coastal environments. Traditionally, SSC used to be measured by time consuming and costly point measurements. This method allows the accurate measurement of SSC only for a point in space and time. Remote sensing from air-borne and space-borne sensors have proved to...
