WebTechnique two: Sediment analysis Aims To examine the sorting of beach material, either across the beach profile (following the sample lines used for profiling) or across the width of the beach (linking to the process of longshore drift) To investigate the effect of management structures, for example groynes, on the sorting of beach material 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 ...

WebThe swash slows, runs out of momentum, then slides back down toward the water. Some of the backwash sinks into the sand. The backwash has a little less energy to carry sediment down the beach so the beach gradually grows in size with the development of a summer berm. The summer beach profile is broader and with a more gentle slope. WebBeach profiles can also be used to calculate cross-sectional area and the amount of beach material present.
