First off, what exactly is a jetty?
A jetty is a structure that projects from land out into water. A pair of jettys can be used to close off a channel. Jettys can be used as walkways, breakwaters, or both. The term derives from the French word jetée, “thrown”, signifying something thrown out.
While jetties typically can’t stop a current, they might be able to slow some beach erosion. As a result, they can assist the beach’s surrounding areas in maintaining their general sand distribution.

Jetty Materials
Large rocks, boulders, or cement slabs are typically thrown into the desired location to create a jetty. Unlike a solid seawall, this will permit some water to pass through, but it will also achieve the desired result of thwarting the current. By having a larger porous area, the stone will also lessen some of the effects of the waves.
Jetty Benefits
In addition to helping to stop the current, building a beach jetty will prevent any caught sand from washing too far down the beach. But once the building is done, others will soon be forced to move in the direction that the current normally flows. This is because areas immediately downstream would experience erosion at an accelerated rate in the absence of additional jetties. This is as a result of the cessation of upstream beach deposition of sand.
These structures frequently help anglers venture a little further out into the water, which is one of their secondary advantages. One of the most fruitful near-shore fishing methods is jetty fishing. Fish species can hide out in large numbers among the rocks, which is almost like a near-shore coral reef. Anglers frequently climb up the rocks by themselves, but in some places, fishing piers are constructed over the stones.
Jetty Harbor Entrance
The design and purpose of a jetty harbor entrance are similar because both stop currents from passing through and depositing sand. These jetties, however, are constructed to prevent sand from entering, unlike the majority of jetties. Any sand that makes the channel shallower than it should be could seriously harm shipping because the deep water channels are required so that larger watercraft can enter and exit.
What Is A Jetty On The Beach?
Despite the fact that jetties can be found on lakes and rivers, the ocean and beaches are where you’ll typically find them. What materials are used to construct jetty structures on the beach or in the water? They are usually made of concrete or stone piles. On either side of a coastal entrance on a beach or shoreline, stones or concrete are positioned to provide protection from the elements. See more about What Is A Calcutta In Fishing Tournament?
What Sets A Jetty Apart From A Breakwater?
If you’ve been wondering how a jetty differs from a breakwater, it does so by rerouting or stopping the longshore current to stop erosion. As an alternative, a breakwater is constructed out into the water with the main objective of establishing a secure harbor, marina, or anchorage for vessels while safeguarding the coast from strong swells and waves.
You won’t need to wonder, “What is the purpose of a jetty?” if you see one while you’re out on the beach (and hopefully catching a few fish).”.
The End
A jetty is a narrow structure that’s built to stretch from land out into the water. Some jetties act as docks or piers for boats.
In addition to providing access for pedestrians to boats or fishing spots, man-made jettys frequently serve as a barrier to prevent beach erosion. Typically, stone, wood, or concrete are used to construct jetties. Jetty comes from the French jetee, which means both “a throw” and “a projecting part of a structure,” or “a part that’s ‘thrown out’ beyond the main structure.”
Best wishes.
