<p>METHOD OF RAISING AND EXTENDING AN OCEAN BEACH A method of forming and extending the width of an existing sand beach (10) at an ocean (14) sea shore by raising the level of the beach. The method includes the construction of a barrier (20), preferably from concrete, in a configuration having a cross section in the form of a substantially equilateral triangle but with a rounded apex (40) at the top. The barrier is constructed at the low tide water level (12) and the apex is approximately 12 to 18 inches below the high tide water level (16). As water flows over the barrier to the high tide level sand is deposited on the land side of the barrier and builds up to the level of the apex. The process can be expedited by dredging and pumping sand and sea water over the barrier. As the sand builds up to the level of the apex on the land side sand also is deposited on the ocean side, thereby totally submerging the barrier so that the barrier does not interfere with bathers or sea turtles or the like.</p> |
