A beach renourishment sand snare and a method or its employment. A series of metal posts are embedded in the sand, forming a line which is approximately perpendicular to the shore. Semi-rigid mesh panels are slidably placed and secured between adjacent posts. Each mesh panel, once immersed in the surf, tends to acumulate sand. The sand will eventually accumulate to the point that the shoreline will advance seaward of the mesh panel. Once this occurs the particular mesh panel is removed and transferred to the seaward end of the line of posts. Likewise, the posts on the landward side can be removed and transfered to the seaward side, thereby "walking" the assembly to seaward. The process thereby accumulates sand and advances the shoreline.
