Abstract
In response to current low water levels on Lake Huron, and to predicted further lowing over the next 50 years, The Friends of Sauble beach are undertaking a long-term program to restore the dunes at the back of the recreational beach. Elevation data collected with a global positioning system in the spring and fall of 2003, were analyzed in a geographic information system. Results will be used to outline the basic geomorphology of the system. Changes in the longshore beach, in the transport from beach to dune, and in the growth of the dunes are the focus of this study. This paper presents a comparison between using a triangulated irregular network (TIN) and an interpolated digital elevation model (DEM) to accurately map the beach. A DEM was created using Kriging, an interpolation method. The TIN provides the best results for visual representation while maintaining the ability to perform accurate, volumetric analysis of sand moving in the system. The maps created from this study are the baseline for monitoring the changes in the beach and dune system.
