The Sediment Transport Demonstration Channel is designed to perform most of the experiments and demonstrations usually undertaken in much larger laboratory flumes, but at much lower cost and without need of technical support. Sand is placed along the channel bed, between the inlet tank and the overfall discharge weir. Water is circulated around the system at a selected flow rate. The channel slope is adjusted by means of a screw jack to which is attached a slope indicator. The channel sides are transparent in order that bed profile changes can be readily observed, and a section of one side is provided with graphical grid. This channel is mounted on to the manual jacking system, which provides positive step adjustment, via a hand wheel, with slope 0 to 10.
