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

  13. Sediment and Contaminant Budgets • Sources and sinks • New data and studies • Sediment supply decreasing • Proposed alterations • Revising sediment budget • Legacy contaminants in bed • Add sediment and PCBs to salinity box model San Pablo Bay 1951-1983 Jaffe and Smith, in review Uncles and Peterson 1995

  14. Sedimentation StudiesScientific Integration • Physics • Chemistry • Ecology • Watershed • Wetlands • Oceanography

  15. Sedimentation StudiesProgrammatic 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
