| 摘 要： | 在杭州湾浅滩上采用底座式ADCP测得单点的漫滩潮流流速、流向及同步水位的变化过程,并在此基础上建立平面二维潮流数值模型,分析整个潮滩上的漫滩潮流过程及其特征。在模型漫滩边界上采用向上取水位值的处理方法,使得模型计算稳定,并获得了稳定逼真的漫滩潮流模拟结果。模拟结果表明:漫滩潮流模拟过程与实测资料基本一致。因此在漫滩潮流模拟中向上取水位值的边界处理方法是可行的。研究成果为漫滩潮流的数值模拟提供了一种较实用的漫滩边界处理方法。 |

| Abstract: | Floodplain flow velocity was measured by acoustic doppler current profilers, through which direction and water level were measured simultaneously, in the Hangzhou Bay, and a two-dimensional numerical model of the tide was established to analyze the process and characteristics of floodplain flow. By the method of taking water level up on the floodplain boundary, a stable realistic simulation result was obtained, which that was consistent with the measured data, suggesting that this boundary treatment was feasible in the floodplain flow simulation. The research has provided a more practical boundary treatment approach to the numerical simulation of floodplain. |
