SummaryWetlands provide critical habitat for a wide variety of plant and animal species. A large number of wetlands are under severe environmental stress, mainly from urban development, pollution, and rising sea level. We propose to help protect this special environment by providing remotely sensed observation of the hydrological conditions in the wetlands. In a previous study (Wdowinski et al., 2004, 2005; Kim et al., 2005), we demonstrated that L-band and C-band InSAR can measure water levels in the Everglades with a vertical precision of 5-10 cm and horizontal resolution of a few hundred meters. Here we propose to use short acquisition intervals SAR data to investigate to suitability of X-band InSAR to wetland hydrological applications. We will test the technique in the Everglades region of south Florida, where we obtained a lot of experience and hydrological knowledge. After testing and calibrating the method in the Everglades, we will expand our study to other wetland regions, including Louisiana (southern US), Chesapeake Bay (east coast US), Pantanal (Brazil) and several other wetlands regions that we havenít determined yet. Currently we are supported by National Institute of Water Research (NIWR), which funds our project "Space-Based Monitoring of Wetland Surface Flow (2004FL76G)" for time period 9/2004-8/2006 with $158,687. We have submitted other research proposal to the South Florida Water Management District, the Department of the Interior and NSF for further funding of this line of research.
