  2. Agenda • Introductions • By-Task Progress • Problems • Miscellaneous • Lab Visit

  3. Introductions • Researchers: • Project Management Committee: • Visitors:

  4. Project Background • Develop knowledge to address the issue of solids accommodation in Texas Department of Transportation low-water crossing structures (not bridges). • To develop design guidelines to assist in building multiple barrel systems that mimic the necessary stream behavior to facilitate solids migration.

  5. Progress by Tasks • Brief by-task report. • Task 1: Literature Review • Task 2: Screening Tools • Task 3: Quantitative Modeling • Task 4: Data Analysis • Task 5: Reporting

  6. Task 1: Literature Review • TM1 submitted. • Copies on server • Database(s) assembled. • QA/QC complete, still finding inconsistencies, but small fraction of the database.

  7. Task 2: Screening tool(s). • Database dependent • QA/QC on-going as just reported • Tools in-progress to allow database use.

  8. Task 3: Quantitative modeling. • Laboratory system functional. • Have solids in-place and will demonstrate today. • Have USGS provided satellite uplink to capture measurements. • Most instruments are ready • Camera lens choices and other methods still in-progress before begin production experiments.

  9. Task 4: Data Analysis. • 2-D/2-phase computer program (UH researchers) to guide experiments. • MIKE-3D CFD computer program (TTU) to extrapolate to larger scales. • CAP-R (Culvert Analysis Program – R) to provide design and performance guidance. http://waterdata.usgs.gov/tx/nwis/uv/?site_no=333509101470800&PARAmeter_cd=00065,00060,00062,72020,00054

  10. Task 5: Reporting. • SAR due end of August • Monthly reports on server; July 2010 should be there. • TM1 submitted

  11. Problems Encountered • Taking TTU longer to start experiments than anticipated. • Weir calibration • Nuisance issues. • Leaks, computers failing, etc.

  12. Miscellaneous • Anticipate some additional model building expenses first quarter FY11. • Would like to visit some systems in FY11.

  13. Laboratory Tour
