Conceptual Model for Sediment Transport in SF Bay Presented to CFWG June 10, 2009
Background (Craig Jones, Sea Engineering) • Understanding of contaminant fate and transport must be developed through a thorough understanding of hydrodynamics, sediment, and then contaminant transport in the system. • Overall, robust descriptions of hydrodynamics and circulation patterns exist in San Francisco Bay • Although a great deal of outstanding work in sediment transport in the Bay has been done, a comprehensive well-accepted conceptual site model has not been developed. • Numerical models of sediment transport in San Francisco Bay have been application specific and do not address many of the needs for understanding contaminant transport.
Background (Craig Jones, Sea Engineering) • Without a good basic quantitative understanding of hydrodynamics and sediment transport processes, it is extremely difficult to develop a quantitative understanding of contaminant transport • The most quantitative description of transport in the Bay can be, and has been to an extent, compartmentalized into understanding of various “hot spots”
Proposal ($25k) • Goals: • to develop a conceptual model of sediment transport in San Francisco Bay • use existing data only (i.e., no field component). • integrate and interpret existing information on sediment transport in natural and urbanized estuaries • attempt to extend that information to the Bay • attempt to elucidate the influence of nearshore regions (i.e., margins) on the overall sediment budget. • identify critical information gaps • help local stakeholders manage sediment, and contaminants, more effectively • Deliverable: • technical report summarizing understanding of sediment transport in SF Bay
Proposal ($25k) • Potential collaborators: • Dave Schoellhamer (USGS) • Craig Jones (Sea Engineering) • David Ralston (WHOI) • USGS Woods Hole • Patrick Barnard & Dan Hanes (USGS Santa Cruz) • Others ?
