Thus, it is imperative that any coastal development be built inland from the shoreline. Facilities for
tourist resorts should be located as far away from the shore as possible. Locating these facilities
directly on the shoreline pollutes nearshore waters with increased surface runoff, and greatly
increases the chances of storm and wave damage and the ultimate loss of the beach.
The following figure shows the consequences of poorly planned changes in shoreline, leading to
erosion and complete loss of a beach:Any construction along the coastline must be carefully assessed for its possible effects on
sediments. Pay special attention to any structure that may interrupt the normal movement of sand
along a beach; this will inevitably cause build-up of sand on the up-current side, and erosion of
sand on the down-current side.
Any construction that modifies the shoreline
will invariably change currents, wave action, tidal fluctuations,
and the transport of sediments along the coast.
Beaches can erode away if development is sited inappropriately.
