Coastal Features of Deposition

Coastal features of deposition are landforms created when waves, tides, and currents drop or deposit the materials they carry, such as sand, shingle, or mud, along the shore. This happens when the energyEnergy is the ability to do work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. Units of Energy: The SI unit... More of the water is reduced, making it unable to carry heavier particles.

Deposition is common in sheltered areas of the coast, such as bays, river mouths, and behind headlands. Over time, the build-up of these materials forms distinctive features like beaches, spits, bars, tombolos, and sand dunes. These features are important for protecting the coastline, supporting wildlife, and providing areas for human activities.

1. Beaches:

Beaches are formed when materials like boulders, stones, gravel, and sand carried by sea waves are deposited along the coast. This process is mainly caused by constructive waves , which build up the coastline.

One important process involved in shaping beaches is called longshore drift . Longshore drift happens when waves approach the shore at an angle (about 45° ), usually due to the direction of the prevailing wind .

This causes the waves to move materials along the shore in a zigzag
