一、杰德航道的自然条件杰德航道通向威廉港,自然条件十分有利。虽然埃姆斯、威悉、易北和爱德等河口均易受到宽广河口潮流以及上游变化的水流和形成咸水带的影响。然而杰德是个海湾,不受岸边任何主要水流的影响(见图1)杰德海湾是在12～16世纪由暴雨洪水冲刷形成的,具有特殊的水力特征,属于冲刷性海湾。由于强潮的影响,

First, the natural conditions of Jed waterway Jed waterway leads to Wilhelmshaven, the natural conditions are very favorable. Although estuaries such as Ames, Weser, Elbe and Ed are susceptible to a wide estuarine and upper-flowing water currents and the formation of a salt water belt. Jed was a bay, however, and was unaffected by any major currents on the shore (see Figure 1). Jeddah Bay was formed in the 12th to 16th centuries by storm floods and has a special hydraulic feature and belongs to the scouring bay. Due to the impact of the tide,
