Resumen:
This paper discusses the contribution of multipolarizationradar data in monitoring flooding events in wetland areas ofthe Delta of the Paraná River, in Argentina. The discussion is basedon the comparison between radiative transfer model simulationsand ENVISAT Advanced Synthetic Aperture Radar observationsof two types of marshes: junco and cortadera. When these marshesare flooded, the radar response changes significantly. The differencesin radar response between the flooded and nonflooded conditioncan be related to changes in the amount of emerged biomass.Based on this, we propose a vegetation-dependent flooding predictionscheme for two marsh structures: nearly vertical cylinders(junco-like) and randomly oriented discs (cortadera-like).
