泥沙随机起动的简化模式

A Simplified Model for Stochastic Incipient Motion of Sediments

泥沙的起动既有随机性，又有模糊性，据此作者将模糊数学方法引入泥沙起动研究。建立了直接反映泥沙随机起动特性的起动流速计算模式，该模式得到了实测资料的检验。这一模式可以体现泥沙起动的随机性。

The incipient motion of sediments is not only stochastic but also fuzzy. Based on this fact, fuzzy mathematics has been introduced to the study on incipient sediment motion. a calculation model for the incipient velocity, which has taken the stochastic characteric into account, has been built. The theoretical formula have been verified with factual data. The model can illustrate the stochastic characterics and reflect the reality of incipient sedment motion.
