&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;[https://www.ciria.org/ItemDetail?iProductCode=C793F&amp;amp;amp;Category=FREEPUBS&amp;amp;amp;WebsiteKey=3f18c87a-d62b-4eca-8ef4-9b09309c1c91 Groynes in coastal engineering (CIRIA C793)], published by CIRIA in 2020, defines infragravity waves as: ‘Waves with a typical period of 25s to 250s much longer than the wind waves and swell waves from which they receive their energy (via the grouping of these source waves). They generally have a much lower height than wind and swell waves but can significantly influence shoreline processes such as run-up.’&lt;br /&gt;
