By analysing published papers on the Yangtze (Changjiang) estuary and hydrological and sedimentary data of Yangshan Harbor sea area, many similarities between Yangshan Harbor sea area and the Yangtze estuary are identified. These similarities indicate that: 1) Turbidity Maximums and mouth bars in estuaries are mainly caused by the hydraulic balance in the stagnating flow area of estuaries; 2) the accumulating area of sands caused by stagnating flow area is often located on the narrower side of the stagnating flow area; and 3) the location of fine sediments area caused by stagnating flow area is well identical with the location of the stagnating flow area. Both Yangshan Harbor area and the Yangtze estuary are the high developmental areas in the future. In-depth studies on these similarities between Yangshan harbor area and the Yangtze estuary will have theoretical and practical significance.

Key words: similarity, stagnating flow area, Turbidity Maximum, mouth bar, Yangshan Harbor, the Yangtze estuary
