【摘要】 本文利用控制体积法对沿水深平均的二维水流及泥沙微分方程进行了离散，建立了二维潮流泥沙数学模型，并利用连云港附近的潮流及含沙量资料对模型进行了验证计算．验证结果表明，无论是水位、流速、流向，还是含沙量都与实测资料符合良好．由此可以看出，本模型不仅能应用于潮流泥沙计算，而且可以推广到各种平面不恒定流的泥沙冲淤计算中．更多还原

【Abstract】 In this paper, based on the discretization equations of 2 -D tidal current, the sedimentation mathematical model is developed and verified by the mesured data of tidal level, velocity and sediment concentration. The computational results are in good agreement with the field data mesured in Lianyungong Harbour.更多还原
