Means and method for controlling beach and sandbar erosion

摘要

A means and method utilizing porous collector bags open at their upper ends and secured successively along a feeder line, one end of the feeder line being anchored in a wave area, and the other end extending onto a shore area; the collector bags being urged progressively by wave action toward the anchored end of the feeder line and caused to fill with sand to the extent that the bags settle on the bottom of the wave area in overlapping relation causing the formation of an erosion preventing groin- like deposit; thereby increasing the area and height of the bagged sand deposit. The feeder line and bags at the shore end may be wrapped as a drum from which the feeder line and bags are drawn into the wave area.
