Abstract

In order to further study the vertical velocity profile with suspended sediment in an open channel, a series of experiments were conducted in a flume. The time average velocity data were calculated by the measured time average velocity data, and compared with the results obtained from a dip modified log law for the vertical profile of the open channel flow. The results indicate that the time-averaged velocity profile is in accord with the dip modified log law. However, under different conditions of flow and sediments and boundary, the related parameters in the dip modified formula are different. The study of this paper can deepen the recognition of vertical distribution in open channel flow.
