Product Description

ADJUSTABLE SECTION CHANNEL

A transparent, inclinable flow channel through which water can be recirculated by a pump over a mobile bed to demonstrate the whole range of bedforms from incipient particle movement to bed wash-out
The channel slope can be adjusted within the range 0-10%
The working section of the channel is 1.55m long, 78mm wide and 110mm deep
A model undershot weir and bridge pier are included for local erosion demonstrations
A water level gauge is supplied to calibrate the overshot weir
To study the hydrodynamic phenomena of the open surface streams in variable inclination channels
Reach an inclination maximum of 1.5 °
