The land ward displacement of the shoreline caused by the forces of wavesand currents is termed as Coastal Erosion. The Coastal areas have become moreprone and vulnerable to natural and human made hazards which lead to CoastalErosion. The Shoreline retreat is recognized as a burgeoning threat because of globalclimate change and other anthropogenic activities that alter the naturalprocesses of sustaining beaches and coasts. Coastal Erosion mainly occurs whenwind, waves and long shore currents move sand from shore and deposit itsomewhere else. The sand can be moved to another beach, to the deeper oceanbottom, into an ocean trench or onto the landside of a dune. The removal of thesand from the sand sharing system results in permanent changes in beach shapeand structure. The impact of the event is not seen immediately as in the caseof Tsunami or Storm Surge but it is equally important when we consider loss ofproperty. It generally takes months or years to note the impact of Erosion;therefore, this is generally classified as a -Long Term Coastal Hazard-. Thepresent paper attempts to describe a Review on Coastal Erosion Process,Parameters’ affecting, and methodologies are adopted to identify the erosionand recommend a solution.
