洪量

Using the flood data from three hydrologic stations in the Yangtze river, the temporal scaling properties of flood volume is studied with scaling theory.

以长江流域3个水文站的洪水资料为例，应用标度理论，对洪量随历时变化的标度特性进行了研究。

The results demonstrate that the variation of annual maximum flood volume with duration has a simple scaling property in a certain period of time.

研究结果表明：在一定的历时范围内，年最大洪量随历时变化具有单标度性质。

On shaping the main channel on a certain section of the lower Yellow River, the required proper value of floods W~ 0.32Q~ 0.37 is fixed. If discharge is greater, the required flood volume can be reduced;

就塑造黄河下游一定断面的主槽而言，所需洪水动力特征值W0.32Q0.37是一定的，若流量较大，则需要的洪量可减少；

And a scaling lognormal model of flood volume is introduced to represent the affection of temporal scale of duration in annual maximum flood volume distributions.

并提出了洪水洪量的对数正态分布模型来表征年最大洪量分布中历时的尺度影响。
