Key Difference – Jetty vs Pier
The terms jetty and pier are often used interchangeably to refer to a structure that extends from the land out into the water. Even though these terms are frequently used as synonyms, there is a key difference between them. The main distinction between a jetty and a pier is that a jetty shields the coastline from currents and tides, while a pier does not impact the current or tide due to its open structure.
What is a Pier?
A pier is a platform on pillars that projects from the shore into the water. Piers are typically supported by well-spaced pillars or piles, and this open structure permits the tide and current to flow through relatively undisturbed. Piers are usually made of wood, and their size and complexity can vary. They are constructed for several purposes and may have different meanings depending on the location. In Australia and North America, the term pier often refers to a cargo handling facility, while in Europe, it is mainly associated with pleasure pier. Piers serve various functions, such as handling passengers and cargo, providing berths for smaller boats, and offering fishing spots for anglers without boats.
What is a Jetty?
A jetty is a long, narrow structure that extends from the shore into the water, typically made of wood, stone, earth, or concrete. Unlike a pier, a jetty has a solid wall down to the water bed and is not raised with the support of pillars. As a result, a jetty protects the coastline from currents and tides since its solid structure can redirect the current. However, this distinction is often not considered when naming piers and jetties, as these two words are commonly used as synonyms. Jetties can also be used to connect the land with deep water farther away from the shore to dock ships and unload cargo. They often flank either side of a river as it enters the water to prevent silting at the mouth.
What is the difference between Jetty and Pier?
- Jetty is a long, narrow structure that stretches from the shore into the water, while pier is a platform on pillars projecting from the shore into the water.
- Jetty can change the path of the tide and current, while pier allows the tide and current to flow through relatively undisturbed.
- Despite their differences, these two terms are often used as synonyms.
