1. A method of reclaiming land along a shoreline or offshore by causing the deposit and retention of particulate material utilizing a plurality of spaced groynes, each groyne including a plurality of spaced stanchions which support at least one screen means having upper and lower portions and side edges, and the at least one screen means being elevatable with respect to material being deposited and wherein the screen means is formed having a plurality of openings therethrough through which water will flow and cause the particulate material to deposit but which are of the size to prohibit passage of larger solid material carried in tidal currents comprising the steps of:

  • a) placing the stanchions in spaced relationship relative to one another extending from the shoreline or offshore;

    b) mounting the at least one screen means to the spaced stanchions so that the lower portion thereof is engageable with the shoreline or offshore to thereby create a buildup of newly deposited solid materials adjacent the lower portion thereof;

    c) preserving the buildup of newly deposited solid materials by periodically elevating at least the lower portion of the at least one screen means so that the lower portion thereof is maintained substantially at the height of newly deposited solid materials.
