将有回水顶托影响的河段视为多输入－单输出系统，把水位过程视为时间序列，用时间序列分析最优控制理论，建立了可考虑回水顶托影响的水位过程预报模型。提出了在棱柱形河道情况下，以时段水位涨差作变量时，模型中各参数应满足的物理性约束条件；较好地解决了长江荆江河段中受回水顶托影响的石首站的水位过程预报问题，为水位过程预报提供了一条不同于水文学途径和水力学途径的建模途径。
The river sections affected by backwater support are regarded as multi-input-single-output system. The water level process is regarded as time series, and the optimal control theory is analyzed by time series. The water level process prediction model which can consider the influence of backwater support is established . In the case of prismatic channel, the physical constraints that the parameters of the model should meet in the case of prismatic channel with variation of water level rise as a variable are well solved, and the Shishou Station The water level process forecasting problem provides a modeling approach that is different from hydrological and hydraulics approaches in water level process forecasting.
