Groynes often form significant elements of the coastal protection schemes around the coast of England and Wales. Investment costs associated with their construction, maintenance and decommissioning is significant. Management practices have evolved as research has developed and practical experience, for instance with new materials, is gained. Recognising this, the Environment Agency, SCOPAC and CIRIA have identified the need for further guidance on the management of groynes. The document would extend and update CIRIA’s existing guide, particularly in terms of maintenance and materials.
