With the topographical data of river network in 1980s and at the end of 1990s, the characteristics of fluvial process after 1980s were analyzed by comparison of the variations of the talweg and capacity of the main river courses, the average altitude of the riverbed, and the width-to-depth ratio of riverbed profiles.
