Abstract
Wetland Interferometric Synthetic Aperture Radar (InSAR) is a relatively new application of the InSAR technique, which enable us to detect water level changes in aquatic environments with emergent vegetation[1, 2]. It provides unique hydrological observations of wetland and floodplains with high spatial resolution that cannot be obtained by any terrestrial-based method[3–5]. The previous studies indicate that longer wavelength SAR systems (L-band), horizontal (HH) polarization of the radar pulse, and short repeat orbits provide best results. We investigate new ALOS PALSAR dual-pol (HH/HV) data in terms of detecting water level changes in various wetland environments using InSAR technique, and detecting flow patterns and flow discontinuities, which can be useful for wetlands restoration.
