摘要:
采用分布点源扩散模型结合平面二维粘性泥沙数学模型建立了模拟河口区开放水域抛泥输移的新方法,并对澳门水域疏浚抛泥的迁移过程进行了数值计算,计算结果表明,受潮汐水流的影响,淤积主要在抛泥点附近较小范围内,淤积量最大点不在抛泥点。

Abstract:
A new method simulating the movement of dumped silt in open estuarine waters is developed and the movement process of dumped silt in the surrounding water body of Macao is numerically calculated by using a distributed point source diffusion model and a 2 D visco sediment mathematical model. Results show that the silt mainly deposits in a small scope around the dumping point and the heavy deposition is not corresponding to the dumping point because of the influences of tidal current.
Key words:  dumped silt,diffusion,mathematical model,Macao water body
