摘要
利用已经建立的海域泥沙迁移扩散动力计算的数学模型, 计算了河口流场、河口倾倒区疏浚泥的沉积厚度和扩散范围. 结果表明, 常向波浪是河口泥沙迁移扩散的原因和动力,而深槽处较大的潮流速也是泥沙迁移扩散的原因之一. 对于泥沙不同的年倾倒量所引起的沉积厚度问题, 也进行了对比计算.
This paper employes a built mathematical model of dynamic computation on the transfer and diffusion of silt in the sea region. The field of a tide current, deposit thickness and diffusing area of dredged silt in the estuary region are computed. Result shows that constant direction waves, as well as higher velocity of a tide current in the deep channel are one of the reason and dynamics to the transfer and diffusion of silt in the estuary region. A computation of comparision is executed for deposit thickness, which is produced by different pouring quantities of silt in a year.
