jetty

A jetty is a structure built into a body of water, typically made of stone, wood, or concrete. It extends from the shore into the water and serves various purposes, such as providing a docking area for boats and ships, protecting harbors from waves and currents, and facilitating water access for recreational activities. Jetties can also help to manage sediment flow and shoreline erosion. They are important in maritime infrastructure, aiding navigation and improving safety for vessels entering or leaving ports.
