摘要
在传统的马斯京根法的基础上将入流过程通过样条插值法,求得Δt时间内中点的入流量,联立平衡方程和槽蓄方程,应用最小二乘法原理,增加一个入流系数C3,求出演算出流量系数C0,C1,C2,C3的最优估计值.此法具有效率高,演算流量误差小特点,操作易行.
Based on the traditional method, the river flow routing with spline curve is simulated and the input flow value of the middle time t ＋0.5△t is calculated by combining equilibrium equation and channel storage equation and adding a imput flow coefficient C3 the most optimal parameters of output C0,C1 ,C2and C3 are calculated with the least square algorithm. This mehod can quickly reach the most optimal value and has been applied in river flow routing with satisfied result.
