Beach accretion device and system that induces accumulation of sediment suspended by beach waves

A beach sand accretion and collection apparatus, the apparatus comprising:

• a footprint defined by an athwartship axis and a bow-to-stern axis;
• a base extending in a parallel orientation relative to the footprint;
• a port athwart sheet, and
• a starboard athwart sheet;
• each said athwart sheet is planar from a lower edge to an upper edge, wherein the lower edge is supported by the base, and wherein the upper edge defines, in part, an apex of the apparatus;
• wherein the port athwart sheet and the starboard athwart sheet are disposed on opposing sides of the bow-stern axis such that the port athwart sheet and the starboard athwart sheet extend in opposing directions along or at least parallel with the athwartship axis;
• the base extending between the two athwart sheets for receiving accreted beach sand thereon;
• and
• each said athwart sheet is oriented at an acute angle of incidence relative to the footprint as said sheet extends rearward from the lower edge to the upper edge,
• whereby a void is defined by the upper edges of said athwart sheets.
