Coastal Erosion Processes

Coastal Processes Erosion U S National Park Service There are four main processes of coastal erosion. these are corrasion, abrasion, hydraulic action and attrition. corrasion is when destructive waves pick up beach material (e.g. pebbles) and hurl them at the base of a cliff. over time this can loosen cliff material forming a wave cut notch. Much more commonly, coasts are subject to breaking waves. these involve significant mass displacement and a considerable loss of kinetic energy as they break on a shoreline. this energy is not dissipated over a short distance where the shore gradient is steep, but over a greater horizontal distance where it is shallow.

Coastal Processes Erosion U S National Park Service Learn about the natural and anthropogenic causes and effects of coastal erosion, and the different types of erosional processes and landforms. explore examples of sea cliffs, caves, stacks, and arches formed by waves, currents, and mass wasting. Coastal erosion is a natural process which occurs whenever the transport of material away from the shoreline is not balanced by new material being deposited onto the shoreline. many coastal landforms naturally undergo quasi periodic cycles of erosion and accretion on time scales of days to years. Learn about the natural and human induced causes and effects of coastal erosion, the loss or displacement of land along the coastline. find out how waves, currents, tides, wind, ice, and sea level rise shape the coast and its features, and how different types of erosion control methods are used. Learn about the natural process of coastal erosion, how waves, currents, tides and sediments shape and reshape the coastline. discover the different types of coastal erosion, such as abrasion, hydraulic action, solution, corrosion and attrition, and their examples.

Coastal erosion is the process by which local sea level rise, strong wave action, and coastal flooding wear down or carry away rocks, soils, and or sands along the coast. Coastal erosion is a natural phenomenon that can be exacerbated by human activities and by storms and tsunamis. in modules 2 and 3, we briefly touched on the natural processes of coastal erosion. we discussed the role of sediment movement and deposition in the evolution of coasts. Coastal erosion is a natural process where wind, water, and other environmental factors wear away coastal land. while it has always been a dynamic force in shaping coastlines, it has gained increasing importance due to the exacerbated effects of climate change, human activities, and sea level rise. Coastal erosion wears away land due to waves, currents, and weathering. the rate of retreat depends on rock composition, wave intensity, and protective features like dunes or vegetation. softer coastlines erode faster than rocky shores, where resistance to wave action slows the process.
