温州港地处浙江省东南部瓯江下游(北纬28°01′.6,东经120°39′.3),为一河口港。这项研究的试验点设在状元桥(离河口出海处约7海里)。这里水深3米,水质混浊,呈土黄色,透明度在0.l米以下。大潮升5.1米,小潮升3.8米,大潮涨落流速3节,最大可达5.5节。水中含盐量低,而且雨季和旱季之间有很大差别。即旱季或高潮时盐度比较高,而雨季或低潮时基本上是淡水。例如8月30日高潮时含盐量11.56‰,平潮12.54‰,低潮1.47‰。
Wenzhou Port is located in the lower reaches of the Ou River in southeastern Zhejiang Province (latitude 28o 01.6, longitude 120o39’.3) and is an estuary port. The test site for this study is located at Zhuang Yuanqiao (about 7 nautical miles off the estuary). Where the water depth of 3 meters, water quality is turbid, earthy yellow, transparency below 0.1 meters. The tide rises 5.1 meters, the small tide increases 3.8 meters, the tidal fluctuation velocity 3 sections, the maximum reachable 5.5 sections. Salt is low in the water, and there is a big difference between the wet and dry seasons. That is, the salinity is higher during the dry season or at high tide, and is basically freshwater during the rainy season or low tide. For example, at the climax of August 30, the salt content was 11.56 ‰, the flat tide was 12.54 ‰, and the tide was 1.47 ‰.
