Coastal Systems - How Wind Creates Waves Geography tutor2u

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. WebIntense storms and higher seas create more winds, waves, and floods, leading to increased coastal erosion. Hurricanes can wash away sandy barrier islands, leaving coastlines and islands unprotected from storm surge. Waves and winds can carry away beach sand little by little, shrinking scenic beaches.

WebMay 20, 2024 · The shape of a sea coast and the shape of the ocean floor both make a difference in the range and frequency of the tides. Along a smooth, wide beach, the water can spread over a large area. The tidal range may be a few centimeters. In a confined area, such as a narrow, rocky inlet or bay, the tidal range could be many meters. Webrefraction of waves affects erosion, transportation, and deposition along the coastline. Well, and again, we find erosion at headlands because that means material is removed from the headlands and transported into embayments where the wave energy is less. The effect of this is that it tends to straighten out a coastline over time
