Abstract
Field investigations of the hydrodynamics and the resuspension and transport of particulate matter in a bottom boundary layer were carried out in South San Francisco Bay, California during March-April 1995. The GEOPROBE, an instrumented bottom tripod, and broad-band acousti Doppler current profilers were used in this investigation. The instrument assemblage provided detailed measurements of 1) turbulent mean velocity distribution within 1.5 m of sediment-w interface; 2) characteristics of 3-D tidal current in the water column; 3) friction velocity u* or bottom shear stress and bottom roughness length zo; 4) hydrodynamic conditions conducive for s resuspension; and 5) circulation patterns which are responsible for transporting suspended particulate matter in South San Francisco Bay. An unusual flow event was recorded by the instruments during March 8-11, 1995. A 3-D numerical model was implemented which re qualitatively, the unusual observations and supported the hypothesis that the unusual flow event caused by a combination of wind driven circulation and weak neap tides.
