水位等效实时修正法
Research on the real-time correction with equivalent stage
本文在对双向波水位演算模型的实时修正中考虑了水位和河宽的相关关系，引入等效水位概念，将此应用在递推最小二乘估计算法中，进行水位实时修正。选用曹娥江感潮河段洪水资料，分别采用传统AR模型和水位等效实时修正法，比较修正结果。分析结果表明，采用水位等效实时修正方法能获得比AR模型更好的修正效果，得到了满意的预报精度。
In this study, considering the relation of stage and river width in real-time correction of bi-directional propagation stage routing model, the concept of equivalent stage is introduced and is applied in the recursive algorithm of least squares estimation to correct real-time stage. The study of the effect of the real-time correction with equivalent stage relative to the conventional AR model in Caoejian tidal reach shows that the real-time correction with equivalent stage can obtain better correction effect and satisfactory forecast precision.
