摘要 将传统的单位线等权倍比迭加线性汇流系统改造为具有动态变化功能的非等权时变倍比迭加因子的汇流预报模型,用以逼近洪水的非线性汇流系统。本法与传统单位线汇流预报方法相比,洪峰流量预报精度提高了10%以上,单位线卷积方程加入非等权倍比迭加因子,应用卡尔曼滤波技术,改进和创新了传统单位线汇流预报方法。 The traditional unit-line forecast system for flow concentration based on equal weight multiple superposition was modified into a dynamic forecast model for flow concentration based on non-equal weight time-varying multiple-proportion superposition factors in this paper.By comparing this method with the traditional unit-line forecast one for flow concentration,the forecast accuracy for peak flow is increased by more than 10%,the unit-line convolution equation is incorporated into the non-equal weight multiple superposition factors,in combination with Kalman Filtering Technique,the traditional unit-line forecast method was improved and innovated.
