  1. San Francisco Estuary Institute Item #3f Dynamic modeling in a representative watershed (Guadalupe) Michelle Lent, John Oram, and Lester McKee Sources Pathways and Loadings Workgroup May 6th 2010

  2. San Francisco Estuary Institute Item #3f Status update • Project put on hold in Sept. 2009 to leverage results of other studies, e.g. WY 2010 monitoring in Guadalupe • TRC approved carrier-over funds for 2010 • Project to resume shortly • Current status: • Fully calibrated and validated hydrology model • Partially calibrated sediment model • Data partially collated for pollutant (Hg & PCB) model

  3. San Francisco Estuary Institute Item #3f Phase 2 (sediment, Hg & PCBs model) timeline

  4. San Francisco Estuary Institute Item #3f Proposed Phase 3 - model improvements & usage • Extend model timeframe to include WY2008-2010 • Allows for further Hg & PCBs calibration to Guadalupe River sampling data collected in recent years • WY 2010 hydrology and rainfall will be preliminary data from USGS and Water District • Split lumped treatment of PCBs into the nine homologue groups • Model land management scenarios • Investigate impacts of land-use change and LID/BMP implementation scenarios of value to WG • Although not a focus of this group – we could also explore climate change scenarios

  5. San Francisco Estuary Institute Item #3f Proposed Phase 3 budget options
