The channel is of a rectangular cross-section supported by steel frame. The channel sides are made of clear acrylic with tilting controlled by a manual screw jack. Sediment Flow Channel is a self contained bench top open channel for studying bed forms with change in flow and slope as well as flow phenomena without sediment. A stainless steel head tank with a stilling baffle provides a smooth flow. A fine strainer is provided in the storage tank to trap the sand sediment. The water is discharged from the channel via a built in rectangular weir to the storage tank.
Experiments:
Flow over fixed gravel bed.
Fixed smooth bed flow.
Local scour.
Mechanics of sediment transport.
Bed form hysteresis.
Flow over mobile sand bed.
Flow structures.
Depositionary features and fancies.
Computational work.
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.

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.

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 simplest type of sedimentation is the settling of a dilute suspension of particles which have little or no tendency to flocculate. In these circumstances, the prediction of clarification rates and their scale-up to plant design is relatively straightforward.
Sedimentation is a process used widely in the clarification of water and waste water. Particles settle from suspension in different ways, depending on the concentration of the suspension and the characteristics of the particles.
Information from batch tests for such systems forms a vital part of the search for the optimum design and operation of industrial sedimentation tanks. The Sedimentation Studies Apparatus allows demonstration of these different characteristics for any chosen sediment/water system. For higher concentrations where inter-particle effects become significant and where agglomeration may take place, different regimes of settling rate occur, known as 'zone' settling A.
Five equal sized glass cylinders are mounted vertically on a backboard incorporating measuring scales. Solutions containing different amounts of suspension can be placed in the cylinders and the differences in sedimentation rate observed by measuring the changes in height of the various solid/liquid interfaces with respect to time. Each of the cylinders may be removed from the board for washing, filling and mixing of the solid particles.
The whole apparatus is bench-mounted and provided with back lighting. An accurate balance (not supplied) is required for weighing the solids.
The equipment includes the following accessories necessary for a self-contained facility: stop clock, three plastic beakers of 2 litre capacity, specific gravity bottle.
The Sedimentation Tank allows to study the hydraulic and efficiency characteristics of the sedimentation by means of a special rectangular section tank. The unit is fitted with an ink injecting device in order to visualize the flow lines obtained in the settling tank. The sludge, which is kept in suspension in the preparation tank by a stirrer, is sent to the sedimentation tank by a variable speed peristaltic pump together with a water flow rate adjusted through a manual valve. The group is supplied with manuals which describe all parts of the unit, the installation and utilization procedures, as well as many exercises with the relative results.
