| 摘要: |
| 应用FVCOM建立了三维潮流泥沙数学模型,根据实测水文资料,对杭州湾开展了三维潮流泥沙验证,结果基本满意.应用模型计算了杭州湾大潮期间涨落潮泥沙输运过程,通过平面、立面的泥沙分布特征,成功再现了杭州湾潮流泥沙的运动过程.尽管模拟精度达不到平面二维模型的水平,但为三维潮流泥沙模型在强潮河口湾的应用作了重要的探索,通过进一步完善模型参数及分析,模型可以应用于涉水建筑物对附近三维水沙影响的分析评估,可为强潮河口湾开发、水环境保护及生态建设等提供更加丰富的研究成果,具有广阔的应用前景. |

| Abstract: |
| The region across the Hangzhou Bay is one of the most economically developed areas in China.There are lots of projects constructed in the Hangzhou Bay,which change the transport of current and sediment in the water area.The sediment transport in the Hangzhou Bay,a huge tidal estuary,is very complicated due to the effects of river runoff,wave and tide.The cohesive sediment is reciprocating its motion under the force of tide flow which comes dominantly from the Yangze River.Although 2D model has succeeded in ... |
