WebOrder Now. Hypothesis. For my investigation we studied a 550m stretch of beach between Lochranza and Catacol on the Isle of Arran, as shown on the OS map (page 2). On this beach it consisted of many granite and phylite pebbles. Phylite could have ended up here from erosion from the cliffs by abrasion. WebSwash carries sediment of all sizes up the beach, but weaker backwash can only transport smaller particles down the beach. This leads to a sorting of material in the foreshore zone, with larger, heavier shingle (pebble-sized sediment) at the back of the beach, and sand drawn back closer to the sea.

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.
