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.
