1 Sediment Dynamics Drive Contaminant Dynamics David Schoellhamer Greg Shellenbarger Neil Ganju U.S. Geological Survey Jay Davis Lester McKee San Francisco Estuary Institute NASA

2 Why study sediment dynamics? Contaminants are associated with sediment RMP

3 Van Dorn sampler Data retrieval in gage house Fouled sensor and cable Clean sensor and cable Sediment Stations

4 Point San Pablo SSC and Mercury

5 Point San Pablo, 4-day Average 25% above WQO

6 RMP Sources, Pathways, and Loadings Workgroup: What is the loading from the Central Valley? Mallard Island

7 Delta Sediment Inflow Gilbert, Porterfield, Krone, OBA, McKee et al.

8 2000 RMP Pulse of the Estuary Contaminant Distribution: Petaluma River

9 NASA UCD/USGS

12 2000 RMP Pulse of the Estuary Petaluma River Trapped sediment mass Tidal oscillation Persists throughout year Large suspended- sediment concentration Sonoma Creek too

13 Sediment and Contaminant Budgets Sources and sinks New data and studies Sediment supply decreasing Proposed alterations Revising sediment budget Uncles and Peterson 1995Jaffe and Smith, in review San Pablo Bay Legacy contaminants in bed Add sediment and PCBs to salinity box model

14 Sedimentation Studies Scientific Integration Physics Chemistry Ecology Watershed Wetlands Oceanography

15 Sedimentation Studies Programmatic Integration U.S. Army Corps of Engineers (RMP) SF Regional WQ Control Board CV Regional WQ Control Board Calif. Coastal Conservancy/USFWS/DFG CALTRANS/UC Davis CALFED Bay/Delta Program Interagency Ecological Program USGS Place-based Program USGS Federal/State Coop Program

16 Future of RMP Sediment Studies Long-term data: watershed supply Variability of contaminants: Petaluma River Legacy contaminant trends: bed dynamics Development and restoration projects
