Coastal Erosion 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. abrasion occurs as breaking waves, concentrated. Follow. coastal erosion is the wearing away of land and removal of beach sediments by wave action, tidal currents, and other processes. coasts are classified as primary, shaped by land erosion, or secondary, shaped by marine agents. erosional coasts experience active erosion while depositional coasts experience sediment accumulation from rivers.
What Are The Differences Between Weathering And Erosion Worldatlas Pramoda raj. this document discusses coastal erosion and mechanisms. it defines coastal terminology and describes the various agents that affect coastal erosion, including wind, waves, tides, and currents. it also examines the erosional and depositional landforms created by coastal processes, such as headlands, sea stacks, beaches, and barrier. Coastal erosion is a normal process of nature. however, the rate of coastal erosion, and the frequency and intensity of coastal flooding events, are now on the rise around the world due to the changing climate. current responses to coastal erosion are primarily determined by site specific factors, such as coastal elevation, coastal slope, coastal features, and historical coastline change rate. Where the coastline changes direction, or the power of the waves is reduced, material being transported by the sea is deposited. where rivers or estuaries meet, sea deposition often occurs. the deposited sediment builds up over the years to form a long ridge of material (usually sand or shingle). such a ridge is called a spit.

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. this is especially evident on sandy landforms. The coastal zone is that part of the land surface influenced by marine processes. it extends from the landward limit of tides, waves, and wind blown coastal dunes, and seaward to the point at.
