South San Francisco Bay Sedflume Study

SEI conducted a Sedflume analysis for the United States Geological Survey (USGS) on four cores obtained from the mudflats in South San Francisco Bay, California. These cores were collected offshore from three salt ponds currently being restored to tidal influence. The primary goal of this work was to determine the stability of the mudflat sediments adjacent to the salt ponds. The cores were eroded using Sedflume to determine erosion rates as a function of shear stress and depth. Critical shear stresses were also determined for each vertical interval sampled. In addition, each core was sub-sampled at vertical intervals to determine sediment bulk density.
