Description:
Conditions:
- Recirculate both water and sediment
- Water Discharge, Bed Slope, and Water Depth Conditions
Sediment flux measurement capabilities:
- Tipping bucket with load cells for time-series total load measurement for experiments with coarse sediment (>250 micron minimum grain size)
- Sediment extraction from fully mixed return-flow pipe for time-average total load for experiments with fine sediment (<1000 micron maximum grain size)
- Six isokinetic suspended sediment extraction tubes for single-depth-point suspended concentration measurements within the test reach (<1000 micron maximum grain size)
- Instrumentation
- Two Nortek Vectrino II acoustic Doppler velocimeters
- 3.5 kHz Ultrasonic depth profiler on automated linear actuator
- Capable of high temporal and spatial resolution/precision bed topographic profiles over 2.5 m profiling window
- Cameras and webcams for high resolution imagery and live webcasting
- Currently Available Sediment
- Lognormally distributed clean sand, D50 = 320 micron, D15 ~ 125 micron, D85 ~ 650 micron (source: Seminoe aeolian dunes, WY)
- Bimodal coarse sand and gravel
