HR Wallingford’s 2D wave flumes are where the majority of our coastal studies start. We use them to optimise and validate sections of revetment and breakwater before moving on to more complex 3D investigations. Our flumes are equipped with the same range of state of the art equipment and instrumentation as our wave basins, including laser scanning and video capture.
We have two wave flumes that are 40 m long and 1.2 m wide, with a maximum operating depth of 1.0 m. We also have a 100 m long large flume. Each flume is equipped with a wavemaker that can produce both regular and random waves.
Flume tests are generally carried out to assess the performance of a cross-section when incident
waves are close to normal to the structure. To minimise scale effects, relatively large models are constructed with scales ranging between 1:10 to 1:40.
