Waves and currents will reshape the constructed beach fill over time to a more natural “equilibrated” shape by transporting sand from the Flood Shoal ST. AUGUSTINE INLET Borrow Area LEAST TERN dry beach and depositing it offshore within the active beach profile to (Image courtesy of USFWS, Larry Richardson) help dissipate wave energy and provide the intended coastal storm risk management benefits. This process begins immediately after construction, with full adjustment of the beach shape typically N requiring many months or multiple significant wave events. The initial equilibration process may appear to dramatically decrease Davis Shoal the width of the dry beach, but the beach is operating as designed. Borrow Area Once the beach has reached an equilibrium condition, the beach is expected to recede at a slower rate. NOT TO SCALE
