Monitoring flood condition in marshes using em models and envisat ASAR observations
This paper discusses the contribution of multipolarization radar data in monitoring flooding events in wetland areas of the Delta of the Paraná River, in Argentina. The discussion is based on the comparison between radiative transfer model simulations and ENVISAT Advanced Synthetic Aperture Radar ob...
