Presentation Transcript

  1. Illinois Sediment Acoustics OSW Sediment HydroacousticActivities Workshop Timothy D. Straub, P.E., Ph.D. Collaborators: Beaulin, Boldt, Bohall, Bosch, Domanski, Draper, Duncker, Goodwin, Husko, Legg, Lynch, Jackson, Johnson, Johnson, Oberg, Prater, Roseboom, Schrader, Straub, Szupiany

  2. Illinois Sediment Network Background 13 • 15 Sediment Gages • ~2,000 samples per year • 7 Cooperators • 5 Technicians in 3 offices • Project Oriented • Dam Removal • Restoration • OPERATIONAL NOT A RESEARCH focus • i.e. 5 Sediment Acoustic sites slow addition 5 2 4 4

  3. Site 1: • Predominantly Agricultural • Drainage Ditch 14 mi2 drainage area Up-looker used Nearly 100 % fines in suspension No near field corrections

  4. Sediment Concentration and Attenuation Coefficient Two October Storms at Kickapoo (05579630)

  5. Sediment Concentration and Attenuation Coefficient October 2009 Storms at Kickapoo (05579630)

  6. Site 2: • One of the largest contributors of sediment to the Illinois River 1,636 mi2 drainage area Up to ~25 % sands in suspension Side-looker: on-going problems with debris on instrument Wake zone?

  7. Partial cleanup of data (negative slopes taken out) Results with only two cells used -no near field correction -wake zone?

  8. LISST-SL Experience and Testing Results in Illinois FISP Funded 2011-2012

  9. Typical Bridge Setup

  10. Automation Software Development Beta Sediment Stationary Add-in by Boldt, Szupiany, Czuba, and Oberg into VMT by Parsons, Jackson, Czuba, Mueller, and Oberg

  11. Beta Add-inAnimation

  12. FUTURE Illinois Sediment Network

  13. Previous Peak 34.56’ Previous Peak 37.24’ Previous Peak 39.01’ Previous Peak 26.04’

  14. Next Steps for OSW? • Compile data from across the nation/world • Interim guidelines • Three or more iterations emerging • Verification dataset • Utilizing existing index velocity sites • 10x10x(200+200)=$40,000

  15. Additional Complications • Setup • Launches • Data transmission • Cables • Temperature • Power • Silting • Debris

  16. Measured, and Water and Sediment Corrected Backscatter

  17. MultipleWater Corrected Backscatter Readings

  18. The SAME Multiple Readings, but forSediment Corrected Backscatter
