摘  要：本文简要论述了涌潮在河口区域产生并向河流上游传播的数学描述方法。文章通过观测，收集得到了若干个河口涌潮的数据，同时这些河口处涌潮形成的条件进行了考虑，认为涌潮的形成主要取决于潮汐的大小、河流本身流量的大小以及河口断面深度这3个因素，同样，这3各因素也控制着海水侵入河口的距离、海水和河水混合的程度以及河口处泥沙的运动的规律。文章还考虑了世界上最大的河流发生涌潮的河口处的水流运动类型，并分析了其对于海水入侵河口范围的影响。本文最后指出塞纳河口（法国）和钱塘江口（中国）由于河道整治对涌潮条件和咸水入侵河口的范围的影响，并对两者进行了对比分析。

Abstract：Approaches to the mathematical description of bore propagation upstream a river in its mouth area are briefly reviewed. Data on some river mouths, where bores were observed, are given, and the conditions of their formation are considered. The existence of a bore is determined by tide magnitude, river runoff, and the depth profile in the estuary. The same factors govern seawater penetration distance into river mouths, the degree of mixing of seawater and river water, and the regularities of sediment motion at river mouths. The types of water circulation at the mouths of the greatest rivers, where bore takes place, are considered, and its effect on seawater intrusion range into river mouths is analyzed. The results of comparison of the effect of channel training on bore existence conditions and the propagation range of saline water into the estuaries of the Seine (France) and Qiantang (China) are given.
