Groynes in Coastal Engineering - A CIRIA Guidance Webinar – June 2020
Construction Industry Research and Information Association
Groynes often form significant elements of the coastal protection and flood defence schemes around the UK's coast. Their principle purpose is to act as a physical impediment to the movement of material, whether longshore, cross-shore through lateral extensions, or a combination of both. Through this they retain and reorintate the beach as required.
Investment costs associated with their construction, maintenance and decommissioning can be significant. Management practices continue to evolve as research develops, new materials are used and practical experience is shared.
