A jetty is a man-made structure typically built along coastlines, rivers, or lakes to manage water flow and protect shorelines from erosion.
It consists of a series of rocks, concrete blocks, or wooden pilings extending outward from the land into the water.
Jetties help control the movement of sand and sediment, prevent the accumulation of silt in harbors, and create sheltered areas for boats and ships.
They are also used for fishing, as they can provide a stable platform for anglers. Jetties are crucial for maintaining navigable waterways and protecting coastal areas.
