Material can be transported along a beach via longshore drift;
- Waves approach beach at an angle
- Material is pushed up the beach by the swash in the same direction as the wave approach
- As the water runs back down the beach the backwash drags material down at right angles to the beach line
- Over a period of time sediment moves in this zig-zag fashion down the coast.
Material can also be transported along a beach at low tide when the sand dries out by the wind (usually forming sand dunes)
Material may also be transported up and down a beach by attrition. Waves may have fairly high energy so will pick up material and may loose energy further up the beach and therefore deposit it there.
Might also be moved by saltation (waves carry slightly smaller sediment in the same way as attrition)
Waves may be swash-aligned (waves hit beach straigt on, so sediment moved up and down beach) or drift-aligned (waves hit beach at right angles causing longshore drift)
What else can I help you with?
Do jetties cause beach erosion?
Yes and no. It will cause deposition on one side of the jetty and erosion on the other. Deposition: A jetty on a beach interrupts the long-shore drift. Long-shore drift occurs when the current meets the beach at an angle. The swash moves along the beach at an angle and carries sediment with it. it deposits some and washes some back with it. The backwash always returns at 90 degrees, so it carries material along the beach in this way: washing it up at an angle, straight back down, then up the beach again at an angle. This can reduce erosion, as it deposits some with each wave. This material will eventually end up all deposited on the beach when it reaches the jetty as it will trap the sediment. Erosion: On the other side of the jetty however, refraction of the waves caused by the jetty will direct them more sharply in towards the beach, so they are at less of an angle, giving a higher force when they hit the beach. These will carry hardly any sediment so very little is deposited. All the waves' energy will then be used for erosion, instead of transportation, which will be greater because of the reduced angle. most beaches have waves coming at an angle, even if it is small. its pretty impossible to get a wave coming at exactly 90 degrees, so long-shore drift should occur on most straight beaches
What are some holidays in Kenya?
There are several types of holidays to Kenya. Safari and Beach holidays are where you can take a safari through some of the main nature reserves in Kenya such as the Masai Mara, and then after the Safari you can relax in a hotel and beaches along the Kenyan coast. Alternatively, you can just go for the beaches. There are four main resorts along the Kenyan Coast. Three are centered around the city of Mombasa: Diani Beach to the south of the City and Nyali Beach and Bamburi Beach to the North of the city.
With longshore drift dose beach sediment move to another one?
Yes, longshore drift is a process where sediment moves along the coast due to the action of waves approaching the shore at an angle. As waves hit the beach, they carry sand and other materials up the shore and then back down with the retreating water, resulting in a zigzag movement of sediment along the coastline. This process can lead to the gradual erosion of one beach and the accumulation of sediment on another nearby beach.

How does sand get transported along a beach?
Sand gets transported along a beach primarily through longshore drift, where waves approach the shore at an angle and carry sediment parallel to the coastline. Additionally, tides and currents can also contribute to the movement of sand along a beach.
Describe how sand moves along a beach?

What is The movement of sand along a beach is known as .?
The movement of sand along a beach is known as littoral drift or longshore drift. This process occurs as waves approach the shore at an angle, causing sand to be transported along the coastline in a zigzag pattern. It plays a crucial role in shaping beach profiles and influencing coastal ecosystems.
How do you use the word along the beach in a sentence?
"He walked along the beach."
What were the men transported by on Omaha Beach?

How can material be moved along a beach?
if you have your whole family you can make a long line and you pass it down littie by little from your car to the spot you want to be in
How does sand and other material on a beach get there?
The sand and other material are deposited on the beach by the wind and tidal currents.
What is the prepositional phrases in the following sentence as I walked along the beach I saw a couple playing Frisbee with their children?
The prepositional phrase is "as you walked along the beach".
Why does the material on a beach affects its gradiernt?
The material on a beach affects its gradient due to the size and shape of the sediment particles. Coarser materials, like gravel, tend to create steeper gradients because they are less easily moved by wave action, while finer sands create gentler slopes as they are more easily eroded and transported. Additionally, the composition and arrangement of particles influence how water interacts with the beach, further affecting the slope. Ultimately, the combination of these factors determines the beach's overall profile.
What is the movement of water and sediment down a Beach caused by waves coming in to shore at an angle?
Longshore drift is the movement of water and sediment along a beach caused by waves approaching the shore at an angle. This process causes sediment to be transported parallel to the shoreline, leading to the creation of sandbars and beaches.
What is an example of along as a preposition?
An example of "along" used as a preposition is: "He walked along the beach." In this sentence, "along" shows the direction in which he walked, next to the beach.
What do you call the area where the shoreline is made up of material deposited by waves?
Much of the coarser sediment material supplied by rivers settles out near shorelines or on beaches.
