清水沟北汊流路入海泥沙对东营港影响的数值分析

Numerical Analysis of Effect of Sediment from Northward Route of Qingshuigou on Dongying Port

本文用平面二维潮流泥沙数学模型，模拟了清水沟流路北汊入海口海域的潮流泥沙扩散和河口淤积延伸方向等问题。在此基础上从流速场分布，泥沙扩散浓度分布及淤积厚度零米线的范围及河口淤积延伸方向等方面探讨了入海泥沙对东营港的影响。结论认为如果按此口门入海，入海泥沙不会对黄河海港产生直接淤积影响。

Two Dimensional tidal current sediment numerical model was applied to simulate tidal current movement and sediment diffusion. Based on this simulation, the effect of sediment on Dongying port was analysed from several aspects below: distribution and movement of tidal current field; distribution of suspended sediment concentration; the line of sediment deposition thickness being zero; deposition extension direction of river mouth, et al. The conclusion is that the sediment cannot directly affect Dongying port, if the sediment empties into sea as the designed location.
