Open-Channel Ssediment Transport

Open-Channel Ssediment Transport

uses sand as an example to demonstrate important phenomena of bed-load transport in the area near the bottom. Open-channel flow without sediment transport is also possible. Discharge can be subcritical or supercritical.
The core element of the experimental flume with closed water circuit is the inclining experimental section. The side walls of the experimental section are made of tempered glass, which allows excellent observation of the experiments. All components that come into contact with water are made of corrosion-resistant materials (stainless steel, glass reinforced plastic). The inlet element is designed so that the flow enters the experimental section with very little turbulence and no sediment can flow back. The tank after the water outlet contains a sediment trap for coarse sand.
The inclination of the experimental flume can be finely adjusted to produce slope and to create a uniform flow at a constant discharge depth.
In addition to bed-load transport in open channels, some models can also be used to observe fluvial obstacle marks, namely scour formation and siltation at structures. A rounded-nosed pier or a sluice gate can be inserted into the experimental section.
The discharge is measured via a measuring weir in the water outlet and a level gauge.
A contrast medium can be injected to visualise the flow conditions.
