“…Currently, there has not been a characterization of the potholes' size in the Canadian prairie region, and their physiological characteristics can vary significantly [31]. To get an idea of the spatial and temporal frequency required for water mapping, a time series analysis was conducted in our study area in Alberta.…”

Traditional on-site methods for mapping and monitoring surface water extent are prohibitively expensive at a national scale within Canada. Despite successful cost-sharing programs between the provinces and the federal government, an extensive number of water features within the country remain unmonitored. Particularly difficult to monitor are the potholes in the Canadian Prairie region, most of which are ephemeral in nature and represent a discontinuous flow that influences water pathways, runoff response, flooding and local weather. Radarsat-2 and the Radarsat Constellation Mission (RCM) offer unique capabilities to map the extent of water bodies at a national scale, including unmonitored sites, and leverage the current infrastructure of the Meteorological Service of Canada to monitor water information in remote regions. An analysis of the technical requirements of the Radarsat-2 beam mode, polarization and resolution is presented. A threshold-based procedure to map locations of non-vegetated water bodies after the ice break-up is used and complemented with a texture-based indicator to capture the most homogeneous water areas and automatically delineate their extents. Some strategies to cope with the radiometric artifacts of noise inherent to Synthetic Aperture Radar (SAR) images are also discussed. Our results show that Radarsat-2 Fine mode can capture 88% of the total water area in a fully automated way. This will greatly improve current operational procedures for surface water monitoring information and impact a number of applications including weather forecasting, hydrological modeling, and drought/flood predictions.

A guide designed to help improve the state of habitat compensation in the Fraser River Estuary by making sound, evidence-based recommendations guided by the findings of Lievesley and Stewart (2016), Assessing Habitat Compensation and Examining Limitation to Native Plant Establishment in the Lower Fraser River Estuary. The findings from this study indicate that only one-third of sampled marsh habitat compensation projects created between 1983 and 2010 are acceptably compensating for habitat losses; and that several riparian habitat compensation projects from this same time period had significant deficiencies. These findings indicate that there is still much room for improvement in the field of habitat compensation in the Fraser River Estuary.
