洪水波分析及波型的模糊识别

Analysis of Flood Wave ond Fuzzy Recognition of Wave Patterns

本文通过无量纲化圣维南方程组,得到一套能定量地描述动量方程中各项对动量守恒贡献大小的无量纲参数。如果将对应于模式和样本——实际洪水波的无量纲参数作为模糊集,则样本洪水波类型的识别就可以由模糊模式识别的原则确定。这一分析方法选用一个实例进行了验证。

In this paper a set of dimensionless parameters are obtained by means of the nondimensionalized Saint-Venant equation. These parameters can quantitatively describe the relative magnitudes of dominant terms in the momentum equation. If the dimensionless parameters of patterns and samples of the practical flood wave are treated as fuzzy sets, the recognition of sample types of flood wave can be decided by the principle of fuzzy recognition. A practical example is provided to prove this analytical method.
