摘要
将一维圣维南方程组与新安江模型结合构成河口地区水位模拟模型,结合区间入流对模型模拟结果影响的试验,提出了采用断面实测信息动态修正区间入流的方法,并对其中的参数进行了分析。将该模型应用于曹娥江感潮河段,结果分析表明,动态修正区间入流能取得很好的修正效果,模型精度高。
Based on the one-dimensional Saint-Venant equations and the Xinanjiang model, the stage simulation model for estuary area was proposed in this paper. Analyzing the effect of local inflow to the stage, the dynamic correction of local inflow considered observed data of the forecasted section was introduced, and it＇s parameters were introduced. The model Nesting the stage simulation model with local inflow dynamic correction, was used to forecast the stage in the tidal reaches of the Cao＇e River. The results showed that the correction of dynamic local inflow can obtain good effects and satisfactory accuracy.
