The Armfield Sediment Transport Demonstration Channel

Most natural waterways and many canals are subject to bed movements caused by the action of the water transporting the material forming the bed in the downstream direction.

The type and rate of movement of the transported material can vary from large stones moved down fast flowing mountain streams, through sand and gravel sizes, to very fine clay particles moved by slow flowing rivers being deposited in lakes and estuaries to form deltas and bottom clay deposits.

A basic understanding of the processes of sediment transport is essential to scientists, engineers and technologists who may be engaged in geology, hydrology, irrigation and other aspects of civil, marine or environmental engineering.

The Armfield S8-MkII allows a range of experiments to be performed to demonstrate the two principle methods of sediment transport in water: bed load movement & suspended sediment transport.

Additional investigations can be undertaken to demonstrate local scour at channel obstructions such as bridge piers, and the secondary flow in channel beds.

Armfield S6-MKII laboratory flow channel

The Armfield S6-MKII laboratory flow channel is one of the most important tools available to the hydraulics or civil engineer whether engaged in teaching basic principles or researching solutions to practical problems. Many applications in fluid mechanics are associated with the flow of water through an open channel where the water has a free surface that is exposed to the air at atmospheric pressure.

The flumes are available in different lengths from 5 to 15m (in 2.5m sections) and examples are installed in educational and research establishments throughout the world.

A comprehensive range of accessories and measuring instruments are available including discharge control, wave generation and a closed loop for sediment transport studies.
