HM 166 Benchtop Sediment Transport Channel Show data sheet (pdf file) Print page
Technical Description
This closed channel of tabletop design is used for investigating the movement of sediment in flows. The flow is generated by a belt-driven bucket wheel; a speed-regulated electric motor is used for the drive. The motor and speed adjuster are on the water-tight base plate. The sediment to be investigated is placed in recess in the working section. To ensure that the water can flow into the working section free of turbulence, an easy to remove flow rectifier is fitted to the front. The oval channel is made of transparent acrylic. To enable the behaviour of the sediment in flows around piles and pillars to be studied, various inserts are supplied that can be placed in the working section.
Learning Objectives / Experiments
· Basic investigations on the formation of dunes and ridges on a river bed
· Determination of the initial conditions for the transport of sediment
· Influence of sediment size and density
· Investigation of the flow of suspended matter
· Secondary flows in the channel bends
· Observation of river bed erosion at bridge pilings and weirs
· Visualisation of flow
· Determination of sediment load
