CHC's Large Scale Wave Flume (LWF) is often used to test two-dimensional sections of coastal structures and study coastal processes at large scale and high Reynold's number. Large scale testing ensures that wave breaking processes and turbulence are accurately reproduced, which leads to improved modelling of processes such as wave loading of structures, wave runup, and the internal flows in breakwater armour and filter layers. Studies in the facility are typically conducted at scale factors on the order of 1:5 or 1:10 leading to highly accurate and reliable results.

The flume is 97 m long, 2 m wide and 2.75 m deep (318 ft x 6.5 ft x 9 ft). The wave generator is a programmable multi-mode machine with active wave absorption capability. It can generate regular waves up to 1.25 m (4 ft) high. The wave absorber at the opposite end of the flume is a progressive porosity expanded-metal absorber that features reflection coefficients less than 5% over a wide range of wave lengths.
