Flume Equipment:

• A 10m long tilting, recirculating hydraulic flume, 30cm wide x 30cm deep. This glass-sided flume can recirculate sediment (up to 22mm in diameter) and also has a viscous flow facility, allowing sediment concentrations of up to approx. 40% by weight. A voltage controlled centrifugal pump enables accurate discharge control and a sediment feed is available to introduce sediment from above the water surface.

• A meter long tilting, recirculating hydraulic flume, 15cm wide x 20cm deep for use with saline flows and viscous fluids. This flume has been used to investigate drag0reduction and viscous sublayer thickening in saline flows and also as an oil-filled flume in investigations of particle rotation

• A 6m long, straight sided continuous density underflow flume, 50cm wide x 150cm deep that enables sustained flows of various viscosity fluids that are fed from two large feeder tanks.

• A continuous density underflow flume – a deep, tilting, ‘T’-shaped tank with a (1.625m long x 0.35m wide by 1.5m deep feeder channel which enters a large tank (1.8m x 1.8m x 1.5m deep) allowing simulation of sustained, radially-spreading flows.

• A 5m long x 0.2m wide, lock-exchange density current tank for pilot experiments on saline and sediment-laden density currents.

• A 6m long x 25mm diameter flow loop for detailed analysis of particle-induced turbulence modulation, using UDVP and PIV.

• A 1m diameter x 1.5m high Perspex tank, and associated input system, for studying jet impingement and sediment erosion and transport in multiphase flows.

• A 10m long x 2.4m wide x 1m deep stream table to enable scaled modelling of braided rivers and their deposits.
