Abstract

A groyne is a relatively long and narrow coastal defence structure, orientated at approximately right angles to the shoreline. Groynes are used to control the natural alongshore movement of beach material under the action of waves and tidal currents. This Technical Note presents, in a systematic manner, information on the layout and performance of groyne systems at forty-five sites on the coastline of England and Wales. The data are presented in tabular form in relation to geometrical and coastal environmental parameters, and perceived performance. The intended use of the data in the design process is explained. Data sheets for each of the forty-five sites are given, summarising both technical and non-technical (e.g. administrative responsibility) data.
