A jetty is a man-made structure that protrudes from land out into water. A jetty may serve as a breakwater , as a walkway, or both; or, in pairs, as a means of constricting a channel. The term derives from the French word jetée , "thrown", signifying something thrown out.

A jetty is a robust man-made structure that completely redirects or interrupts the longshore current and accumulates sand on the updrift side. The only difference between jetties and groins is the extension of the structure.

A breakwater, also known in some contexts as a jetty or a mole, may be connected to land or freestanding, and may contain a walkway or road for vehicle access. Part of a coastal management system, breakwaters are installed parallel to the shore to minimize erosion.

Jetty, any of a variety of engineering structures connected with river, harbour, and coastal works designed to influence the current or tide or to protect a harbour or beach from waves (breakwater). The two principal kinds of jetties are those constructed at river mouths and other coastal entrances.

Apr 5, 2019 · Jetties are another type of shore perpendicular structure and are placed adjacent to tidal inlets and harbors to control inlet migration and minimize sediment deposition within the inlet. Similar to groins, jetties may significantly destabilize the coastal system and disrupt natural sediment regimes.

Oct 19, 2023 · Jetties protect the shoreline of a body of water by acting as a barrier against erosion from currents, tides, and waves. Jetties can also be used to connect the land with deep water farther away from shore for the purposes of docking ships and unloading cargo .

Jan 23, 2023 · A jetty is a structure that extends from the shore into the water, and is typically constructed to protect a channel or harbor entrance from silting and erosion. Jetties can be made from a variety of materials —including rock, concrete, steel or even a combination of materials.

The meaning of JETTY is a structure extended into a sea, lake, or river to influence the current or tide or to protect a harbor.

Nov 13, 2024 · Unlike breakwaters, which protect shorelines from wave action, jetties focus on controlling the movement of sand and water at the entrances of harbors, rivers, and estuaries. This control is vital for maintaining navigable depths, ensuring safe passage for boats and ships.

Dec 20, 2021 · A jetty is a structure perpendicular to the coast that extends out into the sea and protects a harbour or stabilises a coastline. The crest heights of jetties are often well above MSL (see Figs. 10.8 and 10.9). They often function as a breakwater in …
