摘　　要：为缓解盘锦苇田用水紧张的局面,近年来苇田普遍采用上溯潮水与淡水的混合水灌溉。本研究利用双台子河感潮河网的实测水位、流量和最新断面资料,建立了基于Mike11的双台子河口水动力模型,并利用2009年实测潮位资料对模型进行率定和验证。结果显示计算水位与实测值吻合较好,平均误差小于15%。糙率灵敏度分析表明监测点处水位对下游糙率改变最为敏感,中游次之,上游最低;同时发现潮水传播周期及潮差受糙率影响较大。研究结果可为双台子河口区芦苇灌溉、水资源利用、水利规划等提供科学依据。Panjin reed field has been irrigated by mixed water of tidewater and freshwater to relieve water use tense situation In recent years.According to the measured water levels,discharge and river crosssection data of the Shuangtaizi River network,the paper built a hydrodynamic model based on Mike11.The model was calibrated and validated by measured water level data of 2009.The results showed that the mean error was less than 15% .Sensitivity analysis of roughness coefficient revealed that the water levels of observation point in downstream was the most sensitive,while that of upstream was the least.Coefficient sensitivity of middle stream was between upstream and downstream.Meanwhile,the roughness largely affected tidewater transmission period and tidal range.This study can provide scientific basis for wetland irrigation,development and utilization of water resources,and also water planning in Shuangtaizi estuary.
