Abstract

Since 2000, interferometric synthetic-aperture radar (InSAR) has been an effective tool to map 2D water-level changes beneath vegetated wetlands with a high spatial resolution and centimetric accuracy. In the last two decades, SAR images obtained from different wavelengths and polarization modes have been tested across various wetland systems, and InSAR-derived water-level-change maps have improved our understanding of wetland hydrology and hydraulics. In this article, we discuss the feasibility and challenges of applying InSAR to wetland areas, present a comprehensive review of InSAR applications for hydraulic and hydrologic analysis, and discuss future trends.
