Our facilities enable a wide interdisciplinary community to experiment upon a range of simulated natural processes, from flow-sediment transport links in alluvial channels, through the dispersal of sediment in the deep oceans, to particulate transport through pipes and rig vessels.
Our instrumentation includes a range of Particle Imaging Velocimetry systems, which allow investigation of complex turbulent flow fields. We have a range of Anemometry systems that are ideally suited to collecting high spatial and temporal resolution velocity data for the validation of numerical models.
- Long hydraulic flume: A 12 m long, 1.0 m wide and 0.75 m deep, tilting recirculating hydraulic flume.
- Slurry flume: A 8.5 m long, 0.30 m wide and 0.30 m deep, tilting, recirculating hydraulic flume.
- Lock exchange flume: A 5.0 m long, 0.2 m wide and 0.25 m deep flume that can be used to investigate the dynamics of solute- and particulate-driven density currents in both single component ambient fluids and complex, stratified environments.
- Stream table: A 10 m long, 2.5 m wide and 1.0 m deep tank that enables analogue or scaled modelling of landscape evolution, such as rill and headcut development on hillslopes, the effects of base level change on rivers and their deposits, and braided rivers and their deposits.
- 'T'-shaped density current tank: A deep, tilting, ‘T’-shaped tank with a 1.6 m long, 0.35 m wide and 1.5 m deep feeder channel that enters a large tank (1.6 m x 1.6 m x 1.5 m), allowing simulation of sustained, radially-spreading density-driven flows.
- Long density current tank: A 6 m long, 0.50 m wide and 1.50 m deep straight-sided density current flume, allowing the study of the longitudinal evolution of density-driven flows.
- Jet impingement tank: A 1.0 m high, 1.0 m wide and 1.0 m deep Perspex tank that enables the study of jet impingement and sediment erosion and transport in multiphase flows.
- 50 mm pipe flow loop: The pipe flow loop is a 6.0 m long, 50 mm diameter flow loop, enabling the detailed analysis of particle-induced turbulence modulation.
- Liquifaction column: A 1.0 m high and 0.3 m diameter Perspex column, and associated input system. It is designed for visualising and studying sediment fluidisation and associated processes.
- On-site workshop: The School of Earth and Environment possesses an excellent in-house Instrument workshop that both services the SEFDL and manufactures small items of experimental equipment.
