It helps in stopping the Tides and waves from carrying sand away from the beach.
The beach would have rapidly eroded away if not for the rock jetty angled out into the ocean. The natural harbor was improved by building a concrete jetty alongside the deepest channel.
A jetty helps prevent beach erosion by reducing the energy of the waves hitting the shore. It creates a barrier that dissipates wave energy and prevents the movement of sediment along the coast, helping to maintain the beach and shoreline.
After a jetty is built along a beach, it will likely affect local currents and sediment distribution. This can lead to increased erosion on one side of the jetty and potential deposition on the other, altering the coastal landscape. Additionally, the presence of the jetty may impact marine ecosystems and local wildlife, as it changes habitats and water flow. Over time, beach users may notice changes in water conditions and beach accessibility.
The wooden divider on a beach is commonly referred to as a "boardwalk" or "walkway," which provides a path over sand and protects the dunes. In some contexts, if referring to structures that prevent erosion or manage sand, they may be called "groins" or "jetty." These structures help to control beach erosion and protect coastal areas.
jetty
It could be a groin, jetty, seawall, or breakwater. Rip-rap is a common material made up of broken rocks or concrete to protect the shore. A groin is constructed of rocks or wood to maintain or widen beaches that are losing sand. A Seawall is solid concrete designed to protect property from the force of breaking waves. Breakwaters are designed to protect boats. a jetty is a wall of rocks that helps control currents and provides protection for a channel at an inlet.
jetties can effect a shore by protect beaches by trapping pebbles and sand that normally flow down the cost with the current. But thy can also let the sand left over on the beach erode faster.

The Corona Del Mar Beach is found in the state of California. It is a popular place for swimmers. The half-mile long sandy beach is framed by cliffs and a rock jetty.
Jetties and groynes are both structures that stick out from the coast, but which have different functions. A jetty is usually constructed on piles to allow access to boats moored to it. In this way, a harbour can increase its mooring capacity (which increases revenue). Harbours tend to be in sheltered locations, such as river estuaries. Groynes are built in areas which are prone to erosion. They can be made of wood, but are more often constructed from stones. Their purpose is to act as a barrier to erosion, and also to prevent beach sediment being moved along the shore. They form part of strategies for managing coastal erosion.
A homophone for jetty is yeti.
If a jetty were built on a beach, it would likely alter local sediment dynamics and coastal erosion patterns. The structure would disrupt natural wave and current patterns, potentially leading to increased erosion on one side of the jetty while promoting sediment deposition on the other. Over time, this could impact local ecosystems, marine habitats, and beach usability. Additionally, it might lead to conflicts between stakeholders, such as local residents and commercial interests, regarding the changes in beach access and shoreline management.
