Description:
The experimental flume with a closed water circuit has a cross-section of 309x450mm. The length of the experimental section is 5m. 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). The inlet element is designed so that the flow enters the experimental section with very little turbulence. The inclination of the experimental flume can be finely adjusted to allow simulation of slope and to create a uniform flow at a constant discharge depth. A wide selection of models, such as weirs, piers, flow-measuring flumes or a wave generator are available as accessories and ensure a comprehensive programme of experiments. Most models are quickly and safely bolted to the bottom of the experimental section

Learning objectives/experiments
