Monitoring inundation dynamics in paranà river, Argentina, by C and L Band SAR

This paper analyses the SAR response of wetland ecosystems under different environmental conditions and at two different frequencies. We exploited the opportunity of observing the same inundation phenomena by two currently available SAR systems, such as ENVISAT ASAR (C band) and ALOS PALSAR (L band)...
