| Abstract: | We take advantage of radar data which was received in the flood period by the most powerful satellite-borne radar system-ENVISAT ASAR,to compose an image with the Landsat ETM data that was accepted during non-flood period.Then the changed areas between the blood and non-flood period through contrasting the composite image are analyzed. |
