Abstract:

The U.S. Army Corps of Engineers USACE San Francisco District SPN and Coastal Inlets Research Program CIRP are presently performing hydrodynamics, wave, and sediment transport numerical modeling study with the Coastal Modeling System CMS to evaluate a designated dredged-material placement site nearshore the beach erosion hot spot and onshore nourishment alternatives on Ocean Beach, California. Both model results and measurements reveal that tidal forcing is the main process in the nearshore area where the tidal current is predominantly along the shoreline. The calculated sediment transport shows more longshore movement than cross-shore shoreward the dredged-material placement site. The model result also indicates significant sediment erosion at Ocean Beach.
