Equipped with a random, segmented spiral wavemaker, the Circular Wave Basin is unique to Oregon State University. The wavemaker produces a spiral shaped wave with a tangential component at the shoreline. This drives littoral processes around the beach, uninterrupted by end effects of rectangular basins.

The facility is ideally suited for studies on:

  • Longshore currents and mixing
  • Longshore sediment transport
  • Impact of coastal jetties and groins
  • Edge waves and far-infragravity waves
