灌河是江苏省北部最大的一条通海河道,干流长达74.5公里,流经灌云、灌南、响水等县,流域面积达6400平方公里。支流众多,水量充沛,年入海水量达100亿立方米,且四季分配均匀,气候温和,常年不冻,岸线稳定,水深条件好。干流受潮汐影响明显、潮差大,是苏北唯一没有在口门建闸的潮汐干河,因此具有良好的通航条件。目前在燕尾港和陈家港已建有3000吨级专用盐码头各一座,以及小吨级地方码头多座。3000吨级以下海轮可全年随潮通航,向东出海,北至连云港、青岛港,分别为24和106海里;南至上海为386海里。沿灌河西上,可贯通大运河、长
Guanhe is the largest one in the northern part of Jiangsu Province. The main river reaches 74.5 kilometers and flows through Guanyun, Guannan and Xiangshui counties. The drainage area reaches 6,400 square kilometers. Many tributaries, plenty of water, the annual intake of 10 billion cubic meters of water, and the four seasons evenly distributed, mild climate, year-round non-freezing, shoreline stability, water depth conditions are good. Mainstream tidal influence is obvious, tidal range, is the only northern Jiangsu tidal gate without gates, so it has good navigation conditions. At present, there are one 3,000-ton special salt wharf in each of the three ports of Dove-tail and Chenjiagang, and the more than one-ton local wharf. Seaworths below 3,000 tonnage can be navigable with the tide throughout the year, eastward to the sea, north to Lianyungang, Qingdao Port, respectively 24 and 106 nautical miles; south to Shanghai for 386 nautical miles. Along the irrigation west, through the Grand Canal, long
