Groynes in coastal engineering (C793) - new guidance 

CIRIA is delighted to announce the much anticipated Groynes in coastal engineering (C793) guidance is now available to download from the CIRIA website.

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.

 
CIRIA’s new guidance reflects the evolution of research in beach & groyne management practices including the use of new & more sustainable materials.


Jonathan Simm, co-author of CIRIA guide, Technical Director, HR Wallingford
commented “This revision of the well-used CIRIA R119 report was the brainchild of the late Prof Andrew Bradbury, who had started to assemble a document on timber groyne maintenance before his untimely death. The author team believe that the result captures much of the spirit of what Andy intended, dealing not only with the design of groyne field layouts and profiles but also with materials, design, construction and beach and groyne maintenance aspects. It complements two classic CIRIA guides: the Beach Management Manual and the Rock Manual.”
