As waves approach the coast, they refract in shapes that mirror the coastline. …
WebA Seawall effectively acts as a form of coastal defense by redirecting the energy of a wave made by a storm surge back to the ocean water, protecting the coastline from flooding and reducing erosion of the beachfront. A seawall is a passive structure, which protects the coast against erosion and flooding. Seawalls are often used at locations ... WebWhen the wind blows over the sea, it creates waves.

WebThe slope of a coast is critical to determining how water-level changes will affect it. Steeply sloping coasts experience small shifts in their coastlines as the water level changes; however, because wave action along steep coasts is concentrated within a narrow zone, small water-level increases can result in significant erosion of bluffs or dunes. WebShoreline Effects of Storms. In “Beaches are Moving: The Drowning of America’s Shoreline”, coastal geologist and author Orrin Pilkey discusses the four components of shoreline equilibrium – material, energy, shape, and sea level, and how they interact in the event of a storm.
