WebApr 15, 2024 · As sea-level rise (SLR) and human-made interventions affect coastal currents and sediment transport, coastal barriers have become more vulnerable to the effect of storms, hurricanes, and climate variability. The response of each barrier is unique and depends on wave regime, coastline orientation, weather conditions, bathymetry, and type … WebWooden groynes are a common site on beaches on the UK and Europe. Simple to construct, and reasonably cheap for a form of hard engineering, they are normally installed as groups rather than as a single groyne. The length and spacing between the groynes is determined by the force of the waves, the strength of the longshore drift, and the amount ...
