| 摘要: |
| 本文采用潮流数值模拟的方法，以中国华南的珠江口黄茅海河口为例，进行边摊围垦后湾内期波变形的模拟计算。数学模型在完成了对实测水文资料的验证之后，对黄茅海河口湾边滩围垦的不同工况进行了潮流场的对比计算。计算结果表明，湾内潮差和纳潮量与围垦规模成反比，流速分布的变化与边难围垦位置关系密切。在较浅的边摊上适度围垦，新岸线保持适当的放宽本，对湾内的潮坡变形影响不大。 |

| Abstract: |
| This paper adopts a method of numerical simulation, taking Huangmaohai estuary as calculated example, to calculate tidal deformation due to shore reclamation.Through veri-fication of the measured hydrographic data by the use of the mathematical model,various project schemes of shore reclamation in Huangmaohai estuary are tested for comparison.The results of calculation are: difference of the range of tide and change of the tidal water volume are inversely proportional to the scale of shore reclamation in the bay,and change of the flow velocity distribution is related to the situation and form reclamation. |
