  • Microwave remote sensing or SAR (Synthetic Aperture Radar) data has been employed extensively to map open water bodies and to monitor flood extents, where cloud cover often prohibits the use of satellite sensors operating at other wavelengths. Where total inundation occurs, a low backscatter return is expected due to the specular reflection of SAR signal on the water surface. However, low local incidence angle and wind induced waves can cause a roughening of the water surface which result in a high return signal. It is also mean that the temporal variability (TV) of the backscatter from water bodies is higher than other land surfaces. The Mekong River Delta is a region with very long ...
