Shoreline breakwater for coastal waters

Abstract

As civilization progresses people have a desire to build their homes as close as possible to the ocean and other coastal waters. Due primarily to the attraction of the moon, the ocean's shoreline moves regularly between high and low tide elevations, referred to as the foreshore area. Beyond the foreshore area there are successive areas identified as the trough and the bar areas resulting from the turbulence caused as the incoming waves reach the shallower waters as they approach the foreshore area. The tidal movement of the water, coupled with periodic storm surges causes dramatic shifting of the shoreline, frequently with disasterous results. Concerted efforts have been made to overcome this serious condition, but without marked success. We have devised a system whereby erosion can be prevented. We provide an artificial reef positioned in the submarine beach area, an area in the water that is shallow at low tide and is out beyond the foreshore area and the trough and the bar areas. We place a continuous triangular so-called sea-lift in the submarine beach area to deflect upwardly and slow down the incoming waves to form new trough and bar areas beyond the foreshore area and to shift the foreshore area outwardly. If desired the newly formed beach in the low tide area can be shifted inwardly on the beach by earth moving equipment to increase the useable beach area.
