A jetty is a long, narrow structure that protects a coastline from the currents and tides. Jetties are usually made of wood, earth, stone, or concrete. They stretch from the shore into the water. Currents and tides of an oceancan gradually wash away a beach or other features along the coastline. This is called erosion.

    Summary:

    Jetties are hard structures built at the banks of tidal inlets and river mouths to trap longshore sediment, thereby stabilizing the inlet or river mouth and preventing channel siltation. Jetties are solid and durable and are considered a hard-engineering protection measure.
