Sediment Transport Analysis and Cap Design Criteria for Mission Bay Ferry Landing, San Francisco, CA
Publication: Ports 2019: Port Planning and Development
ABSTRACT
Sediment characterization for material proposed to be dredged for the Mission Bay Ferry Landing (MBFL) and Water Taxi Landing (WTL) in San Francisco, CA, has identified areas with elevated polycyclic aromatic hydrocarbons (PAHs) concentrations that require capping. Analysis was performed to evaluate sediment transport and potential for recontamination of the cap due to transport of PAH-laden sediment from surrounding areas, and to provide design criteria for cap erosion protection design. The analysis estimated sediment movements to the cap from specific and separate surrounding areas during typical and storm conditions occurring in the past 50 years using a fully coupled wave/current/sediment transport model. Results of the analysis show that surrounding areas with elevated PAH concentrations are subject to periodic erosion primarily during storm events, and the volume of incoming cleaner sediments dwarfs the volume of eroded nearby bed sediments, resulting in a negligible recontamination of the cap over time.
