WebDrift alignments Drift alignments are best developed where waves arrive at an angle of 40°–50° to the coastline. They are typically sinuous in detail, with intermittent lobes and cusps that migrate downdrift, and longshore spits and bars that diverge slightly alongshore. Variations in transverse profile occur as these features pass along the beach. WebIn either case, the water in a longshore current flows up onto the beach, and back into the ocean, as it moves in a “sheet” formation. As this sheet of water moves on and off the beach, it can “capture” and transport beach sediment back out to sea. This process, known as “longshore drift,” can cause significant beach erosion.

Conversely, a wider breaking angle, gentler beach slope, and lower wave height slows a longshore current’s velocity.
