Waves going back and fourth.
Destructive waves happen when the backwash is stronger than the swash. =)
...... because the beach has a ..... swash and a ........ backwash.
A constructive interference wave, where two waves combine to create a larger wave, can produce a swash stronger than the backwash. This can happen when the incoming waves are longer in wavelength and have a higher wave height, causing the swash to carry more water up the beach than the backwash can pull back down.
When swash is more powerful than backwash, it can lead to an accumulation of sediment on the beach, creating a wide and flat beach profile. This can promote beach accretion and possibly lead to the formation of a sandbar offshore. Additionally, the increased sediment buildup can provide protection against erosion during storm events.
if you mean backwash (the opposite to swash) its the water of a wave travelling back down a beach, transporting beach material, due to gravitational forces :)
Swash and backwash waves are associated with coastal deposition. Swash waves carry sediment onto the beach, while backwash waves transport sediment back into the ocean. This back-and-forth movement helps build up beaches and contribute to coastal deposition processes.
Swash is when the water of the sea moves up the beach/land. Backwash is when the water of the sea moves away from the beach/sand.
A constructive wave is a powerful wave that surges up the beach with a powerful swash. This is the forward movement of the wave up the beach. It has a weak backwash, which is the backward movement of water down a beach when a wave has broken. Characteristics are: .swash is stronger than the backwash. .Has a low gradient. .Has low energy. .Produces gentle beach profile .Other names are: storm, surfing or plunging waves. .Typical off the SW coast of the UK.
Swash is movement of water up the beach whereas backswash is movement of water down the beach.
When the sea loses energy, it drops the sand, rock particles and pebbles it has been carrying. This is called deposition. Deposition happens when the swash is stronger than the backwash and is associated with constructive waves.
Transverse waves cause matter to move back and forth perpendicular to the direction of the wave. Examples include light waves and water waves.
