Shorelines are in a constant state of fluctuation since sea waves move during high tides. The rising and falling of tidal waves advances or retards shorelines. The dangers of erosion and flooding pose real threats to shorelines, especially during storms. The areas near coastal regions are invariably affected by high tides, thereby creating shoreline displacements. Further sand erosion could accentuate new sea levels and actually displace shorelines permanently. The effects of under oceanic movements affect the course of tides and provide shorelines to be relined.
Furthermore, temporary sandy reinforcing through beach nourishment and other stabilization does not serve many purposes since these fillings are more susceptible to erosion than regular sandy areas and require much more effort to sustain. The unregulated shorelines may move into the sea during high tides, creating shoreline constrictions. Shoreline management is a definite tool that could address the issues raised by flooding and soil erosion along the coastal region. Unplanned constructions and population growth along the coastal areas are major reasons for changes in topography and contribute to pollution of the shores areas, besides endangering marine life.
