The NRC's coastal wave basin (CWB) serves as a narrow 3D basin or a very wide 2D flume. It is ideal for conducting two-dimensional and three-dimensional physical model studies of wave and current interactions with structures and shorelines at medium to large scales.
Long-crested, irregular waves with significant heights of up to 0.4 m (1.3 ft) can be generated. High-efficiency wave absorbers give less than 5 % reflection over a wide range of depths, wave periods and heights. The basin can be configured to generate bi-directional currents, and combined wave+current flows can be modeled.
By erecting temporary partition walls, the facility can be sub divided into several narrower channels for conducting two-dimensional studies of multiple cross sections in parallel. This approach is an efficient method for evaluating the relative performance of several alternative design concepts and for refining preliminary designs. Once the structure's cross section is optimized, the partition walls can be removed and the three-dimensional aspects of its performance can be investigated in the same facility.
The basin can be accessed easily by heavy equipment used in constructing model bathymetries. The basin is also served by a 1-ton traversing gantry crane and a mobile service bridge.
