研究认为： ( 1 )黄河河口口门迳流潮汐区域并非持续保持淤积状态，在特定的来水来沙、边界条件和海洋动力条件下，该区域可以处于冲刷状态； ( 2 )从河口泥沙沉积分配的过程来看：三角洲与滨海区泥沙的沉积变化趋势是基本一致的，各部位的泥沙沉积比例变化基本呈波动状态，且三角洲与滨海区泥沙的沉积比例与来沙量密切相关，基本成正比关系； ( 3 )在口门处，影响泥沙沉淤的因素主要集中在潮汐顶托、口门逐渐加宽、河口门分汊、盐水造成絮凝等，本报告主要对口门加宽，口门西妥理工大学工程硕士专业学位论文分汉对河道淤积的影响进行了定量分析: (一扣根据实测资料首次建立了河赎流路泥沙沉积分配的回归计算式，据此可以预估计算河口不同区域泥沙的沉淤量; 、 5 )本项研究首次论证了河口三角洲岸线动态平衡的概念，并建立了黄河河口来沙量与造陆面积的相关关系，得出了当河口多年平均来沙量维持在3 . 45亿t时其河口三角洲岸线则可能处于动态平衡状态的重要结论; ‘ 6 )本项研究首次提出了河口泥沙优化调控的概念，并对其宏观优化调控模式进行了初步探讨。 | | 8. | By computing the water level and sedimentation processes with and without considering the extension of flow path , the results show that the effect of the river mouth path extension on the sedimentation of the trail channel is a longer period of evolution for several years or even over 10 years , and furthermore , the effect becomes weaker and weaker gradually from downstream to upstream in general
