| 摘 要： | 基于黄河口生态环境需水及其配置研究的需要,以平水年洪水过程资料为基础,在黄河下游河口段建立了一维河流数学模型,对年度内及年际间的流量水位过程进行模拟,研究模型的适用性。结果表明,模型在冬季冰冻期内的适用性较低,主要原因为冬季冰封期使模型运用条件发生改变,模拟结果出现误差;去除冰封时段后,模型适用性得到恢复,满足河段的年内应用;而年际间模拟结果表明,河床高程变动是影响模型精度的主要原因,在充分考虑河床的冲淤变化后,经适当校正,模型在河口段仍具有较高的适用性。

| Abstract: | In the study on Yellow River estuary environmental flow,a one-dimensional hydraulic model using SOEBK was set up based on the flood data in the normal years.And the model applicability was studied.The results show that the model has a low applicability in ice period because of the changing condition of the model running.However,the model has a good running in non-ice period.Then a comparable analysis of simulation shows that the ability of the hydraulic model to correctly compute water levels depends strong... |
