The Importance and Variety of Jetties

A jetty is a structure built out over the water, typically from a shore or a boat, to provide a place for boats to dock or for people to fish. It can be made of wood, metal, or other materials, and may be fixed in place or floating. Jetties are used to protect harbors and shorelines from erosion and to control the flow of water, and they can also serve as a platform for various activities such as fishing, boating, and swimming.

Here are some examples of different types of jetties:

1. Breakwaters: These are long, curved structures that are built out into the ocean to protect a harbor or beach from waves and erosion.
2. Groynes: These are small, rectangular structures that are built perpendicular to the shore to prevent erosion and to promote sedimentation.
3. Piers: These are structures that extend out from the shore into the water, providing a place for boats to dock and for people to fish.
4. Beacons: These are tall, narrow structures that are built on the end of a jetty to provide a navigational aid for boats.
5. T-heads: These are jetties that have a T-shaped structure at the end, which helps to dissipate the energy of waves and prevent erosion.

Overall, jetties play an important role in protecting shorelines and harbors, and they can also provide a platform for various activities and recreational opportunities.
