Description
The Sediment Transport Demonstration Channel, “CAS”, designed by EDIBON, consist of an inclinable channel mounted on a base plate, supported by two supports, with a discharge tank and recirculating pump. This tank is in the Basic Hydraulic Feed System (FME00/B) that contains the recirculating pump.
The channel sides are transparent allowing the observation of bed profile changes, and a section of one side is provided with graphical grid markings to permit quantitative assessments to be made of bedform dynamics.
A water level gauge is included to measure the head over the channel discharge weir and therefore to deduce flow rates from a calibration chart. For demonstrating scour effects of structures on rivers beds, solids models, as an adjustable undershot weir and bridge pier are supplied.
To start a demonstration, sand is placed along the channel bed, between the inlet tank and the overfall discharge weir. Water is circulated around the system at one of the flow rates. The slope of the channel is adjustable.
