Jetty vs. Pier: What's the Difference?
A jetty is a structure projecting into water to influence currents and protect shores; a pier is a structure extending from land over water, typically used for docking boats.
Jetty is a structure that projects into the water primarily to influence water currents and protect shores from erosion. Pier, on the other hand, is built extending from the land into the water, mainly for purposes like docking boats or providing a walkway.
Jetty often serves to protect harbors and coasts by altering tidal flows and reducing erosion. Conversely, a pier’s central function is usually to provide access to boats, serve as a fishing spot, or offer a place to enjoy the seascape.
Constructed from various materials like wood, steel, or concrete, a jetty is typically narrower and longer. In contrast, a pier may be wide and can even support buildings and amusement rides, demonstrating its diverse uses in comparison to a jetty.
In terms of placement, a jetty is usually found at the mouth of rivers or harbors. A pier, however, is typically found in resort towns and coastal cities, underscoring their differing roles in water-based infrastructures.
