| Summary | (Plain Language Summary, not published)
This text reviews studies that address the separation of open water from river ice cover and similar cover types by means of Synthetic Aperture Radar
(SAR) images. It is a deliverable for a project funded by NRCan's Office of Energy R&D that aims to assess and develop Canada's river hydrokinetic potential as a national renewable resource. Specifically, this review will support the development of
an automated approach to identify candidate hydrokinetic turbine sites by means of SAR satellite images. SAR satellites are expected to make good site selection tools thanks to their capacity to detect areas of persistent open water in frozen rivers
irrespective of weather and daylight conditions. Such open water areas may result from high flow rates and thus represent sites of interest for turbine deployment. This review identifies four principal SAR image analysis methods: radiometric,
polarimetric and texture analysis as well as coherent change detection. |
