Groynes are long, narrow structures that form significant elements of the coastal protection and flood defence schemes around the UK's coast. Designed to control longshore transport of sediment on beaches and to deflect nearshore tidal currents, groynes may extend across part of or the entire intertidal zone and are normally grouped together to form groyne systems or fields protecting the land behind beaches from flooding and erosion. Covering the design, condition assessment, maintenance and repair of groyne systems, this guidance updates and replaces the CIRIA TN135 'Groynes in coastal engineering: data on performance of existing groyne systems', published in 1990.
