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。
In this paper, we use the planar two-dimensional tidal current and sediment mathematical model to simulate the problems such as the tidal current and sediment diffusion and estuarine sediment extension in the sea area of Beibei Bay of Qingshuigou. On this basis, the influence of sediment entering Dongying Port on the distribution of velocity field, the distribution of sediment concentration and the range of zero noodle siltation thickness and siltation direction of estuary were discussed. The conclusion is that if we click here to enter the sea, sediment entering the sea will not have a direct sedimentation effect on the Yellow River seaport.
