Recent results about asar observations of wetland marshes

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...

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 (water level, precipitation, and vegetation condition). Two marsh species, named Junco and Cortadera, were monitored. The comprehension of the observed backscattering features was addressed through electromagnetic models developed for these ecosystems. Results are validated with water level evaluations at specific points. A map showing estimated water levels below Junco and Cortadera areas, is presented. Fil:Grings, F.M.
