港口水深

港口水深、浪小、水域开阔、自然条件和航道通航条件较好，具有建设国际集装箱深水港的有利条件。

The port , having outstanding geographical location with deep water , calm seas and vast expanse of waters in the harbor area , makes it an ideal place to construct international container terminal .

江苏沿江港口水深不足、布点密集、重复建设、盲目竞争，长期未得到充分开发，江苏沿海地区在很大程度上影响了江苏经济的发展。

The factors , such as insufficient water depth in the areas near the harbors along the Yangtze River , dense harbor distribution , and repeated harbor construction , and unreasonable competition , hinder the overall development of the harbors and the development of Jiangsu economy to a certain degree .

相对大型船舶船宽大、吃水深的特点，港口内一般水深相对较浅、宽度受限。

Considering the large vessels have big breadth and deep draft , the depth and the width of ports area are limited .

某些港口由于天然水深较浅，需要对天然航道进行较大尺度的挖掘，造成航道内流场流动复杂，对船舶航行安全造成一定影响。

Since shallow depth of certain ports , it needs to increase the scale of natural waterways , resulting in complex flow field within the fairway , affect the safety of navigation .

淤积在断面上的分布也不均匀，泥沙淤积对河口地区的港口及航道水深有一定影响。入海航道由于局部浅段的存在，致使航道水深严重不足，制约了港口的发展。

The water depth of navigation at the port will be affected by the sediment deposition . The shallow water area in an estuary , where the depth of flow is insufficient for navigation , restricts the development of the port .

港口以避风、水深、不於积、航道短、可用岸线长而闻名于世。

The port is famous for wind shelter , deep water , non-accumulation of mud and sand , short sea-routes and long , usable coastline .

为此，本文根据港口航道的声道特点及声传播特性，展开了基于双基地声呐的港口航道水深实时监测技术研究。

Therefore , according to the characteristics of shallow sea acoustic channel and acoustic propagation , a study on the real-time monitoring techniques of water depth in port channel based on bistatic sonar is carried out in this paper .
