Quizplus · Accepted Answer

Breakwaters are specifically designed to protect boats and harbours from the force of large breaking waves. Groins, jetties and seawalls may also provide some level of protection, but they have different purposes and functions. Groins are built perpendicular to the coast to prevent beach erosion, jetties are built to help maintain navigation channels, and seawalls are built to protect the shoreline and human settlements from erosion and flooding.
