AbstractMuch of the coast in the Canadian Maritimes is susceptible to erosion and flooding from storm-surge events and long-term sea-level rise. In recent years significant damage has occurred during storms in both urban and rural areas of the region. LiDAR technology has been employed to develop high-resolution digital elevation models (DEMs) as a basis for production of flood-risk maps. These are required by coastal zone managers and emergency measures officials to plan for the future. This paper presents a summary of the LiDAR surveys conducted in the region to date and reviews the conclusions on exposure to flooding in each area. Although most of the areas considered lie above mean sea level, some areas are dyked and lie below mean sea level. These areas are assessed in terms of their susceptible to flooding by a storm surge overtopping or breaching the dykes.
