This channel is mounted on to the manual jacking system, which provides positive step adjustment, via a hand wheel, withslope 0 to 10.The unit is supplied with manuals that describe each component of the system, installation and utilization procedures andgive many exercises. 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. The Sediment Transport Visualization Channel is designed to perform most of the experiments anddemonstrations usually undertaken in much larger laboratory flumes, but at much lower cost and without the need fortechnician back-up. The channel slope is adjusted by means of a screw jack to which isattached a slope indicator. Sand is placed along the channel bed, between the inlet tank and the over fall discharge weir. Water is circulated around the system at a selected flow rate.
....
The equipment is self-contained and may be bench-mounted in either the classroom or laboratory by virtue of its portability.
A model undershot weir and bridge pier are included for local erosion demonstrations.
A transparent, inclinable flow channel through which water can be re-circulated by a pump over a mobile bed to demonstrate the whole range of bedforms from incipient particle movement to bed wash-out.
The working section of the channel is 1.55m long, 78mm wide and 110mm deep.
A water level gauge is supplied to calibrate the overshot weir.
Three different discharge rates can be selected (and measured) within the range 0.2 to 0.6 litres/sec.
The channel slope can be adjusted within the range 0-10%.
Description:
The unit consists of an inclinable channel mounted on a frame, together with a discharge tank and recirculating pump. The channel slope is adjusted by means of a fine screw jack to which an accurate slope indicator is attached. To commence a demonstration, sand is placed evenly along the channel bed, between the inlet tank and the overfall discharge weir. The channel sides are transparent in order that bed profile changes can be observed, and a section of one side is provided with graphical grid markings to permit quantitative assessments to be made of bedform dynamics. Water is circulated around the system at one of the three selectable flow rates.
Wheelchair, manual assistant-controlled: Transport wheelchair.
POSTURAL SUPPORT: For older CHILD and ADULT users who can sit upright and balanced without additional support.
FUNCTION AND ENVIRONMENT: Standard wheelbase and overall length. For intermittent or short-term transport in healthcare facilities.
SUPPLIED WITHOUT CUSHION.
Inappropriate prescription and fitting of wheelchairs, cushions and accessories may harm the user’s health and/or function. Therefore, this product should only be purchased after consultation with the Medical Devices Unit in Supply Division.

Transportation of Category-A infectious substance, with approved triple packaging.
Leakproof box, with inserts providing barriers.
Compliant design for transportation (infectious substance affecting humans, category A), and approved for Class 6.2 hazardous materials.
Packing capacity:
Tertiary: Very strong cardboard (sturdy enough to withstand a fall from 3 meters high), with minimal dimensions (to reduce air-freight cost), includes integrated space for 0.3L cool-pack (for short-distance transportation) or dry-ice (for long-distance transportation).
Primary pack: Loads up to six standard 5-7ml vacuum specimen tubes.
Secondary pack: Plastic container, Approx. 60x160mm (diam x h), fitted with absorbent material.
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 markings to permit quantitative assessments to be made of bedform dynamics. The unit consists of an inclinable channel mounted on a base plate, together with a discharge tank and recirculating pump. To commence a demonstration, sand is placed evenly along the channel bed, between the inlet tank and the overfill discharge weir. The channel slope is adjusted by means of a fine screw jack to which is attached an accurate slope indicator. Water is circulated around the system at one of the three selectable flow rates.
