Wave Erosion and Deposition Earth Science

Waves continually move sand along the shore. Waves also move sand from the beaches on shore to bars of sand offshore as the seasons change. In the summer, waves have lower energy so they bring sand up onto the beach. In the winter, higher energy waves bring the sand back offshore. Some of the features formed by wave-deposited sand are in Figure

CHAPTER 4 PROTECTION FROM COASTAL EROSION

Figure 4.6 Sand dune coast (modified from ARC [2000] and French [2001]) 3.1.5 Sandy coast. This type of coast consists of unconsolidated material — mainly sand from rivers and eroded headlands, broken coral branches (coralline sand) and shells from the fringing reefs. It can be classified as a soft coast with reef protection offshore.

Sandbar geology Britannica

Sandbar, submerged or partly exposed ridge of sand or coarse sediment that is built by waves offshore from a beach. The swirling turbulence of waves breaking off a beach excavates a trough in the sandy bottom. Some of this sand is carried forward onto the beach and the rest is deposited on the

Stages in Primary Succession on a sand dune.

Where the rate of sand deposition is greater than 30cm per year, they will be outcompeted by Marram Grass. Marram Grass then takes over the process of binding the dunes. This species is less tolerant of exposure to sea water and therefore occurs slightly further away from the sea than the first pioneer species.

These are usually made from stone, concrete, steel, or timber, and are designed to keep sand from entering a ship channel. As sand builds up on against the upcurrent side of the jetties, it can be redistributed along the beach to further reduce erosion. However, much like groins, erosion still occurs on the downcurrent side of the jetties.
