Slide 1Item #6
Watershed Modeling at SFEI
John J. Oram, Lester J. McKee, Mikolaj LewickiSPLWG December 2007
Slide 2Item #6
Objectives
• Improve understanding of monitored watersheds
• Determine sediment and contaminant loads from unmonitored watersheds
Slide 3Item #6
Other Studies
• Bay Area Hydrologic Model (BAHM)– SCVURPPP, ACCWP, SMCWPPP– Model Used: HSPF– Purpose: Stormwater management
• Brake Pad Partnership (BPP)– Gov., Manufacturers, Enviros, stormwater
mngers– Model Used: HSPF– Purpose: Impact of brake pad Cu on South
San Francisco Bay
Slide 4Item #6
Other Studies (continued)
• BAHM and BPP are where we want to be:– multi-watershed models– Water, sediment, contaminant loads
• However, we want to walk … not run.– Develop single watershed models where we
monitor sediments and contaminants– Incrementally add watersheds as we gain
knowledge
Slide 5Item #6
Project #1 : Guadalupe River
• $75k funding for 2008
• Objectives:– Develop HSPF model for
1) Water
2) Sediment
3) Hg and PCBs
– Estimate current loads– Determine proportional flow regime– Estimate long-term avg loads
Slide 6Item #6
Project #1 : Guadalupe River
• Potential Challenges– Reservoirs– Plumbing (e.g., storm drains)– Stream x-sections– Others …
• Would like to leverage SCCWRP– Learn Drew Ackerman’s HSPF secrets– Why use SWMM for BMPs?
