• Lab Visit
Introductions• Researchers:
• Project Management Committee:

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.
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
Task 1: Literature Review
• TM1 submitted.– Copies on server
• Database(s) assembled.– QA/QC complete, still finding
inconsistencies, but small fraction of the database.
Task 2: Screening tool(s).
• Database dependent– QA/QC on-going as just reported– Tools in-progress to allow database use.
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.
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.

Task 5: Reporting.
• SAR due end of August
• Monthly reports on server; July 2010 should be there.
• TM1 submitted
Problems Encountered
• Taking TTU longer to start experiments than anticipated.– Weir calibration
• Nuisance issues.– Leaks, computers failing, etc.
Miscellaneous
• Anticipate some additional model building expenses first quarter FY11.
• Would like to visit some systems in FY11.
