针对俄罗斯模型模拟洪水时其假定不能代表各流域的洪水特性,提取各场洪水的峰现时间进行参数估计和线型优选,将改进后的俄罗斯模型应用于钱塘江流域金华江金华水文站的洪水模拟。统计特征检验结果表明,改进后模型79.63%的时段统计量参数模拟效果优于原始模型,模拟序列统计规律更接近于实测序列。 When the Russian model simulates the flood, it assumes that it can not represent the flood characteristics in each basin, and extracts the peak time of each flood for parameters estimation and linear optimization. The improved Russian model is applied to the flood of Jinhua River Jinhua Hydrological Station in the Qiantang River Basin simulation. Statistical test results show that 79.63% of the time-series statistic parameters of the improved model are better than the original model, and the statistical rule of simulation sequence is closer to the measured sequence.
