| 摘 要： | 泥沙恢复饱和系数是泥沙数学模型中一个非常重要的参数,其取值合理与否将直接关系到利用泥沙数学模型进行河床演变及相关研究的成败.基于三峡水库蓄水后长江中游荆江河段的实测水沙资料,以本河段三峡水库蓄水前多年平均输沙水平作为泥沙输移方程中的挟沙能力,对水库下游非均匀沙恢复饱和系数进行了率定与分析,并在总结其规律的同时从多个方面...

| Abstract: | The sediment recovery coefficient is a very important parameter in the sediment mathematical model,and whether its value is reasonable or not will be directly related to the success or failure of the river evolution or other similar researches,which are carried out by using the sediment mathematical model.Based on the field data of Jingjiang reach in middle Yangtze River after the impoundment of the Three Gorgers Reservoir,the nonuniform sediment recovery coefficient downstream of reservoir is calibrated an... |
