Description :
Rivers with fluvial equilibrium are characterized by bed deformation adjustment. The erosion-deposition area in cross-section reflects this characteristic, which is a base of researching the river scour and deposition evolution by time series analysis. With an erosion-deposition area indicator method proposed in this paper, the time series of erosion-deposition area quantity at Bygl and Shhk stations were obtained with the series duration of 31 years from 1976 to 2006. After analysis of its trend and mutation, 3 different tendencies about the evolution in Inner Mongolian Reach of the Yellow River were observed in general from the quasi-equilibrium phase through a rapid shrinkage to the final new quasi-equilibrium.
