The new Delta Flume in Delft was constructed to facilitate large-scale physical model testing. The new Delta Flume has a length of about 300m, a width of 5m and a height of 9.5m. The maximum wave heights that can be generated are about Hs=2.2m with maximum individual wave heights in the range between Hmax=4m and 4.5m. This unique facility enables physical modelling at prototype-scale or at close-to-prototype scale. Preventing or diminishing scale-effects is especially important for coastal structures in which sand, clay, grass or other natural construction material is being applied. Besides projects with dikes and dunes, structures such as breakwaters, bed protections, monopiles, offshore wind farms, storm surge barriers are scheduled to be tested. Along with new facilities also new measurement techniques have been developed, both for the new Delta Flume and for the other wave facilities (e.g. wave basins). The new Delta Flume completes a set of wave facilities for physical model testing consisting of small and large-scale test facilities and 2D (wave flumes) and 3D (wave basins) facilities.
