Abstract
Long Point is a 35 km long spit on the north shore of Lake Erie. Sediment supply from erosion of bluffs to the west is estimated to be 1.0 x 10(6) m3 yr-1. Some of this transport occurs in the form of migrating longshore sand waves - local beach protuberances with alongshore lengths of 500-2,500 m, and maximum widths at the downdrift end of 50-90 m. These migrate alongshore at rates of 150-300 m yr-1 and the spatial/temporal variation in beach width associated with this is an important control on local dune erosion and accretion.
