Abstract

Using cross section measurement data, the sedimentation rate of the lower Yellow River was determined. This method has the advantage of avoiding the error that may be resulted from sediment load measurement, which is incapable of measuring the near-bottom suspended sediment and bed-load. Based on annual data from the period 1952-1999, correlations between channel sedimentation rate and a number of flow and sediment indices have been established. Then, some multiple equations have been established, which can be used to estimate channel sedimentation rate based on a number of influencing variables including suspended sediment load and its grain size compositing, water discharge and, hyperconcentration flow frequency. These equations may provide some useful information for better environment management in general, and for sediment management in particular, in the Yellow River basin
