Definition
A jetty is a structure projecting out into the water to protect a harbor, coastline, or riverbank. It's often built in pairs to stabilize a channel and prevent sediment from blocking the entrance. Jetties are typically made of rock, concrete, or wood. They help maintain navigable waterways and protect against erosion. Imagine jetties as arms reaching out to calm the waters. 🌊 They guide boats safely into the harbor.
