Summary(Plain Language Summary, not published)
Information about surface water conditions can help a variety of applications including hydrology, meteorology, ecology, and agronomy. Synthetic Aperture Radar (SAR) has been recognized as an important source of data for monitoring surface water. To understand the potential of the RADARSAT Constellation Mission (RCM) to monitor wetlands and watersheds this project examined wetland characteristics that lead to coherence in RADARSAT-2 InSAR data and determined the annual variation in the coherence through in-situ studies. Project results indicate the use of CCD could be an effective approach for monitoring flooded vegetation with the RCM. Results also indicated potential for monitoring water levels using InSAR. With the Canadian RCM being launched in 2018 there will be rapid revisit capabilities which will enhance the operational use of SAR data for assessing wetland conditions and monitoring water levels. Thus there is potential for the RCM to drive a dynamic operational surface water and wetland monitoring system for Canada.
