Description :
Detailed topographic surveys of a site in the Wickaninnish Dunes in Pacific Rim National Park, on the west coast of Vancouver Island near Ucluelet, British Columbia, for the first year post-treatment are compared to a pre-restoration LiDAR baseline survey. The method incorporates inherent spatial structure in measured elevation datasets at the sub-landscape scale and models statistically significant change surfaces within distinct, linked geomorphic units (beach, foredune, transgressive dune complex). Seasonal and annual responses within the complex are discussed and interpreted. All geomorphic units experienced positive sediment budgets following restoration treatment. Further integration of this methodology to detect significant geomorphic changes is recommended, particularly for applications where sampling densities are limited or logistically defined.
