Barriers to the sea 



Beach nourishment is a favorable, but ex- 

 pensive, way to hold the sea at bay (above). 

 Groins and jetties, placed perpendicular to 

 the shoreline, trap sand moving in currents 

 along the shore (left). Bulkheads like this are 

 no longer permitted to protect beachfront 

 structures built after June 1, 1979 (below).
