The purpose of the sand drift fence is to accumulate wind-blown sand to naturally rebuild/renourish a dune or the toe of a coastal bank. A “heavy duty sand drift fence” is for locations where waves and surf are particularly intense, and therefore the fence has to be designed to withstand such forces during storm season (winter & early spring). Subsequently, during the non-storm seasons (late spring, summer and fall), the fence can resume its role in naturally accreting sand for restoring/expanding a dune at the toe of a coastal bank.
