This paper focuses on the use of radar remote sensing for water storage estimation in wetland marshes of the Paraná River Delta in Argentina. The approach followed is based on the analysis of a temporal set of ENVISAT ASAR data which includes images acquired under different polarizations and incidence angles as well as different environmental conditions(More)
The Lower Delta Islands of the Paraná River in Argentina constitute a major coastal tidal freshwater wetland located at the De La Plata River estuary, very close to Buenos Aires City. It is a complex region where the landscape pattern is characterized by mosaics of natural and man made ecosystems. Since the last few years an increased number of SAR images(More)
The inclusion of functional approaches on wetland characterizations and on biodiversity assessments improves our understanding of ecosystem functioning. In the Lower Paraná River floodplain, we assessed the ability of C-band polarimetric SAR data of contrasting incidence angles to discriminate wetland areas dominated by different plant functional types(More)
Wetlands are areas where the frequent and prolonged presence of water at or near the soil surface drives the natural system. Next to Buenos Aires, the Lower Delta islands of the Paraná River constitute a fresh water wetland characterized by a complex mosaic of natural and man made ecosystems and a hydrologic regime defined by the Paraná and De la Plata(More)
Remote sensing tools allow the environmental evaluation of coastal wetlands at a landscape scale, but a deeper understanding is needed of the interactions between biophysical parameters and the electromagnetic signal. The goal of this work was to analyze and quantify the influence of the aboveground biomass and the Leaf Area Index (LAI) on the spectral(More)
The paper describes how ASAR observations and electromagnetic models were used to obtain estimates of water level below two marshes with different vegetations structure in the Paraná River Delta in Argentina. The approach followed is based on the analysis of a temporal set of ENVISAT ASAR data which includes images acquired under different polarizations and(More)
The Paraná Delta is a region stretching through the final 300 km of the Paraná river basin, covering approximately 17,500 km 2 [Kandus et al., 2006] and is located between 32º05'S, 60º48'W, and 34º29'S, 58º30'W, close to the city of Buenos Aires. It is a vast macro-mosaic of wetland types, and has a complex hydrological regime determined by the influence of(More)
