ABSTRACT: The land ward displacement of the shoreline caused by the forces of waves
and currents is termed as Coastal Erosion. The Coastal areas have become more
prone and vulnerable to natural and human made hazards which lead to Coastal
Erosion. The Shoreline retreat is recognized as a burgeoning threat because of global
climate change and other anthropogenic activities that alter the natural
processes of sustaining beaches and coasts. Coastal Erosion mainly occurs when
wind, waves and long shore currents move sand from shore and deposit it
somewhere else. The sand can be moved to another beach, to the deeper ocean
bottom, into an ocean trench or onto the landside of a dune. The removal of the
sand from the sand sharing system results in permanent changes in beach shape
and structure. The impact of the event is not seen immediately as in the case
of Tsunami or Storm Surge but it is equally important when we consider loss of
property. It generally takes months or years to note the impact of Erosion;
therefore, this is generally classified as a “Long Term Coastal Hazard”. The
present paper attempts to describe a Review on Coastal Erosion Process,
Parameters’ affecting, and methodologies are adopted to identify the erosion
and recommend a solution.
