1942年萨瓦林斯基提出的多年调节水库蓄水保证率曲线的方法,已被广泛应用于水库多年调节计算,目前,已经有不少根据萨瓦林斯基方法绘制的蓄水保证率曲线线解图。(如文献[1]),可直接查用。但是,这些线解图是在年径流服从P—Ⅲ(以下均为P—Ⅲ)型且C_S=2 Cv的概率分布下得出的。当Cs≠2 Cv时,就不能直接查用这些线解图。为了使这些线解图在Cs≠2 Cv时也能应用,下面导出一种变换方法。由文献可知,水库蓄水保证率曲线既可采用萨瓦林斯基方法,也可采用水库 The method of adjusting the reservoir water storage rate curve proposed by Zarinsinski in 1942 has been widely used in the regulation of reservoirs for many years. At present, there are many curve solutions of the water storage guarantee rate drawn by Zawalinski’s method Figure (Such as literature [1]), can be directly used. However, these line plans are derived from the probability distribution of annual runoff under P-III (P-III below) and C_S = 2 Cv. When Cs ≠ 2 Cv, you can not directly check these line solution diagram. In order for these line solutions to be applied when Cs ≠ 2 Cv, a transformation method is derived as follows. It can be seen from the literature that the reservoir water retention rate curve can adopt the Zawalinski method or the reservoir
