Probability Formula of Incipient Motion of Non2uniform Sediment
摘要
Abstract
The incipient motion of sediment is one of the most important subjects for the research of river dynamics. In this pa2 per,theprobabilityformulaofincipientmotionofnon2uniformsedimentwasdeducedusingthecombinationmethodofprobabil2 ity and mechanics in consideration of the impacts of exposure degree and shape of sediment on the threshold velocity. The rela2 tionship betw een threshold velocity and threshold probability w as developed. Compared w ith the measured incipient velocity, the formula can reflect the movement of non2uniform sediment accurately.关键词
