Landforms of Marine Deposition

Beach

Main processes: constructive waves, longshore drift, deposition.

Example: Tramore, Co Waterford.

Constructive waves and longshore drift leave large deposits of mud, sand, shingle and larger stones as beaches on our coasts.

All around the Irish coast there are numerous beaches, many of which are major tourist attractions.

For a beach to form there must be,

• A sheltered area to trap sediment,
• Longshore drift to transport material to the beach,
• Constructive waves to deposit beach material between the high and low tide mark.

A tombolo is a landform of marine deposition.

A tombolo is a sandbar or sandspit that connects an island to the mainland.

Tombolos are common around the west coast of Ireland and are made of shingle, sand and stone.
