Headlands can help protect a beach from erosion by acting as a barrier against strong wave action. They also can create different beach environments, such as coves or sheltered areas, based on how they influence the movement of sand and sediments along the coast. Additionally, headlands can affect surfing conditions at a beach by influencing wave direction and shape.
continuous manner due to the action of waves and currents. It is a natural process that helps redistribute sand along the coastline and maintain the beach's shape and size.
Beach drift occurs due to the movement of sand particles along the shoreline. It is mainly driven by wave action, which pushes sand particles in a zigzag pattern along the coast. This process helps to shape beaches and distribute sediment along the shoreline.
The sandy section of the coastline is often referred to as the "beach." Beaches are characterized by their accumulation of sand, pebbles, or other sediments along the shore, shaped by the action of waves and tides. They serve as recreational areas and are important ecosystems for various marine and coastal wildlife.
effect. longshore drift is the combined effect of sediments moved by longshore currents and and beach drift. longshore currents are ocean currents that flow parallel to the coast while beach drift is the resultant zigzag movement along the beach.
long-shore drift
The movement of waves down the beach is called longshore drift. This process occurs when waves approach the shore at an angle and carry sediment along the coast.

Deposition. Rivers carry sediments from the land to the sea. If wave action is high, a delta will not form. Waves will spread the sediments along the coastline to create a beach.
The coastal defenses that hold beach sediments in place are called "groynes." These structures extend from the shore into the water and are designed to interrupt the flow of water and sediment along the coastline, helping to prevent beach erosion. By trapping sand and sediment, groynes can help maintain and build up beach areas.

Waves can cause beach erosion through the process of wave action, which involves the movement of water and sediments along the beach. Strong waves, especially during storms, can remove sand from the beach and pull it offshore. This can result in the gradual erosion of the beach as sand is carried away by the waves.

The accumulation of sediment found along the shore of a lake or ocean is called a beach. Beaches are formed by the deposition of sand, gravel, and other sediments carried by waves and currents, often shaped by tides and weather patterns.
