Abstract
Based on non-uniformity,the grain shape coefficient is introduced.By analyzing influence of shape coefficient and exposure degree,the formulas for calculating equivalent grain and the incipient motion condition of non-uniform sediment are established by the relative exposure degree and shape coefficient.Verified by using the experiment data,the result shows that the experiment data are adjacent to the measured value.
