| 摘 要： | 为探究不同时间尺度边界入流条件对平原感潮河网水动力水质模型模拟精度的影响,以典型平原感潮河网地区的张家港市中部为研究区域,结合野外同步监测数据、自动高频监测数据、常规监测资料等构建了水动力水质模型进行模拟分析。结果表明:时间尺度、开始取值时刻以及调度情况均会影响模拟精度;研究区域边界入流条件、水动力模拟结果和水质模拟结果可信的最大时间尺度为1 h,水质模拟精度优于水动力模拟精度。

| Abstract: | In order to explore the effects of boundary inflow conditions at different time scales on the simulation accuracy of hydrodynamic water quality model of plain tidal river network, taking the middle area of Zhangjiagang, a typical plain tidal river network area, as an example, a hydrodynamic water quality model was constructed based on field synchronous monitoring data, automatic high frequency monitoring data and conventional monitoring data. The results show that the time scale, the starting time and the dispatching conditions have an impact on the simulation accuracy; the credible maximum time scale of the study area boundary inflow conditions, hydrodynamic simulation results and water quality simulation results is 1 h; and the accuracy of water quality simulation is better than that of hydrodynamic simulation. |
