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. 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 greensboro-high point marriott hotel
