Coastal Erosion and Stabilization Techniques Quiz

A breakwater is a hard stabilization structure built offshore and parallel to the beach to protect the coast and create a calm area of water.

A seawall is a hard stabilization structure built near the beach and parallel to the shore to protect the coast from the force of waves.

Hard stabilization structures are built parallel to the shoreline to protect property and coastal structures.

<p>Wave refraction is the bending of waves as they travel towards shallow waters near the shore. Oblique waves created by wave refraction contribute to the longshore drift, which transports sand and sediment along the coast and can result in coastal erosion.</p> Signup and view all the answers

<p>A groin is a hard stabilization structure built at a right angle to the shore. It is used to maintain or widen beaches by trapping sand that is moving down the coast due to the natural action of waves and currents.</p> Signup and view all the answers

<p>A breakwater is a hard stabilization structure built offshore and parallel to the beach. It breaks up large ocean waves, creating a calm area of water near the shore and protecting the coast.</p> Signup and view all the answers
