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.

∙ 10y agoOther names for a jetty are: breakwater, groyne, mole, seawall, etc. They are protective structures of stone or concrete - or more likely built of wood, in the case of groynes - extending into the water from the shore to prevent a beach washing away. They can also be placed to give some protection to an anchorage for small boats.

Name the rock structure that protects the beach from losing sand?
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.

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
