摘要
提出了用四点线性隐格式求解水流方程、用卡尔曼滤波求解河道糙率的一种求解河道水流及其糙率参数反问题的新方法,并应用于淮河水流计算.结果表明,计算水位与实测水位过程完全吻合.
By adoption of the fourpoint linear implicit form to solve water flow equations, a new method is developed for inverse analysis of water flow in river channels and the roughness parameters of the channels based on the Kalman filter, and applied to flow calculation for the Huaihe River. The variation of the water level calculated by the present method is in agreement with the measured data.
