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 functions do dunes play in erosion on the beach?
Dunes are a natural barrier and therefore minimize erosion.
The major cause of weathering and erosion is?
Wind and water are the major causes of weathering and erosion.
What can cause erosion?
wind, water, and ice
What is the main cause of erosion on coastlines?
the water's force and time
What do rivers glaciers wind and waves cause?
Weathering and Erosion.
What do jetties do?
jetties help stop erosion
What are jetties?
helps protect a beach!
Which would not cause a beach to get smaller?
erosion
How does melting snow cause erosion?

Can a aswan dam cause beach erosion?
No it is inland.
Why might some beach property owners oppose the building of jetties?
Some beach property owners might oppose the building of jetties because they can alter natural coastal processes and disrupt the natural movement of sand along the beach. This can lead to accelerated erosion in some areas and increased deposition in others, potentially affecting the overall health and stability of the beach. Additionally, jetties can alter wave patterns and currents, which can impact the recreational value and aesthetic appeal of the beach.
What are the causes and effects of beach erosion?
The main cause of beach erosion is large storms and hurricanes. With the high winds and the increased wave size, the water level rises up and washes away a portion of the beach. Over time, this can cause the beach to become smaller.
How do waves cause beach erosion?
minecraft is awesome play that instead
What is the purpose of jetties?
Jetties are usually for the purpose of controlling erosion in inlets and rivers. They also serve the purpose of protecting harbors and river entrances from the ocean from heavy wave action and storm damage.
Does beach erosion cause climate changes?
No, it's probably the other way round. Climate change will cause beach erosion. Rising sea levels and increased energy in storms and storm surges will damage many beaches.
How is beach erosion related to the climate?
AS climate changes it can cause more storms, higher water levels and a change in the dominant wind direction. All these can create an increase in beach erosion.
What are two problems cause by beach erosion?
you can lose your house also shorelines change
