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.
