UNO Dynamics of Sedimentation Lab
Lab
Tilting flume
Civil and Environmental Engineering 72-foot tilting flume. The flume is capable of recirculating water and up to 5mm sediment as a closed loop. It has an automated slope adjustment via electric jacks. The flume test section is 64 feet long, 2 feet wide, 3 feet deep. Current instrumentation includes:
- 33-foot streamwise linear actuator instrument carriage, with 2-foot vertically mounted actuator for instrument mounts
- Laser topographic profiler capable of full-width swathes at sub-mm precision/repeatability
- Laser PIV/PTV with two solid state laser modules (532nm and 405nm) and cameras for time-resolved PIV
- Ultraviolet lighting for sediment particle tracking studies
- Nortek vectrino II profiling acoustic Doppler velocimeter
- Several Sontek Flowtracker single-point acoustic Doppler velocimeters
- 4 tons local clean river sand
- Storage for additional sediment types and grades
Delta basin
In the coming year, I will be constructing a dual purpose teaching/research delta and river basin lab. This facility will include a 3 m x 4.5 m basin, sediment feeders and recirculation pumps, overhead cameras, and laser topographic instrumentation.
1-D flume
I will be constructing a 4.8 m long, 15 cm wide, 90 cm tall teaching/research flume capable of recirculating currents for bedform experiments, basin height adjustment for 1-D delta experiments, and turbidity current experiments. This flume's primary purpose will be for instructional purposes for Stratigraphy and Sedimentation, Basin Analysis, and Advanced Stratigraphy courses.
Sediment sampling and field hydrodynamics equipment
I will be acquiring sediment sampling and other field equipment to add to the coastal hydrodynamics and sediment transport facilities at the Pontchartrain Institute for Environmental Sciences (for a full list of PIES equipment and facilities - http://new.uno.edu/pontchartrain-institute). All UNO DoS equipment can be made available on contract, and we can help design sampling strategies depending on your needs. Current equipment includes:
Sediment sampling:
- Sequoia LISST-SL2 suspended sediment sampler, B-Reel, stainless davit.
- USGS FISP P-61 point integrated sediment sampler, B-Reels, davits
- USGS FISP BLH-84 handheld bedload sampler with 3.5m wading rod
- 3x USGS FISP DH-48 handheld depth integrated sediment samplers with up to 3m wading rods
- USGS FISP DH-81 handheld depth integrated sediment sampler with up to 3m wading rods
- UMN Livingston piston corer
Hydrodynamics:
- 15x Lowell Instruments Tilting Current Meters (5x TCM-4s and 10x TCM-1s)
- Teledyne RiverPro multi-frequency ADCP 1200 kHz main beams, 600 kHz vertical beam
- 2x SoFarOcean Spotter satellite integrated wave buoys, 1 satellite & 4G integrated buoy
Misc Field Equipment:
- 6 laboratory/field cameras (GoPro hero5 & session, Sony RX100, Sony RX100 V, Canon SX280HS)
- DJI Mavic Air drone, 3DR Iris+ drone
- 2x Emlid Reach RS2 RTK GPS receivers
