Why would sand be deposited behind a small island to form a spit or tombolo?
◦ The tidal affects are trivial behind the island, so the sand is not swept away.
◦ Waves refract around the island and the wave energy is dissipated on the island, allowing quiescent water behind, and sand drift to accumulate behind the island.
◦ The onshore current from one direction piles up sand here.
◦ The island protects the coast from rip currents, preserving the sand.
