月径流和月输沙集中特性模型

 

1.  月径流和月输沙量集中程度的表达方式

(1)    集中指数模型:

式中,为按降序排列的分量百分数累积量;为均匀分配时分量百分数累积量;为最集中分配时分量百分数累积量。

(2)    吉布斯-马丁分散指数模型:

(3)    不均匀系数模型:

式中,为大于月均值的月分量;为月均量;为月均值超过年均值的月数。

(4)    集中度模型:

式中,为月份;为各月所占的角度,总计360°。

(5)    集中期模型:

(6)    变异系数模型:

2.  河流月径流和月输沙集中特性与输沙径流年总量相关分析

(1)    关联系数模型:

(2)    关联度模型:

式中,为比较序列因子数;为样本数;取值0.5为参比因子数。
