Based on data of cross-section measurements obtained during the period 1973-1997, the development of the secondary suspended channel in the lower Yellow River has been studied. It has been found that the period 1973-1985 was the main period in which the secondary suspended channel was formed in the reach above Gaocun station; but in the reach below, the process can be divided into two periods of time. In the period 1973-1985 with high water discharges, large quantities of sediment deposited on the floodplain near the natural levee, resulting in a larger lateral slope of the flood-plain. In the period 1985-1997 with low water discharges, large quantities of sediment deposited within the main channel, and as a result, the channel shrank and the situation of the secondary suspended channel became even more serious.
