麗水沿岸 定置綱 漁場 周邊 海域을 中心으로 潮流의 流向과 流速 및 海水粒子의 連續 移動 狀況을 把握하기 위하여 海水 流動 調査를 實施한 結果를 要約하면 다음과 같다. 1) 麗水海灣의 북쪽 入口에서 小潮期와 大潮期 모두 썰물때의 流向은 南向, 밀물 때는 北西~北쪽으로 흐르고 最强流速은 大潮期의 썰물때 68cm/sec, 밀물때 66cm/sec, 小潮期의 썰물때 37cm/sec, 밀물때 35cm/sec였으며, 또한 22cm/sec 정도인 南쪽 方向의 恒流가 있다. 2) 漁場 周邊 海域의 流向은 小潮期와 大潮期 모두 썰물때의 流向은 南東쪽, 밀물때는 南~北西쪽이며, 最强流速은 大潮期의 썰물때 50cm/sec, 밀물때 40cm/sec, 小潮期의 썰물때 28cm/sec, 밀물때 25cm/sec 이다. 또한, 大潮期의 半日週潮 成分의 長軸方向의 유속벡터가 日週期에 비하여 약 3배 程度의 크기이며, 小潮期는 大潮期에 비하여 半日週潮의 유속벡터가 약 50% 減少하고, 半日週潮와 日週潮의 潮流楕圓의 크기와 長軸 方向이 거의 같아진다. 또, 이 海域에는 大潮期에 11cm/sec, 小潮期에 7cm/sec 程度인 南東方向의 恒流가 있다.

A studies on the sea water circulation was carried out by using droque experiments and tidal current measurement in the coastal water of Yeosu. The direction of tidal current at the north entrance of Yeosu bay was southerly in ebb and northwesterly in flood without the distiction of the neap tide and the spring tide. In spring tide the maximum velocity of the tidal current was 68cm/sec in ebb and 66cm/sec in flood. In neap tide the maximum velocity of the tidal current was 37cm/sec in ebb and 35cm/sec in flood. And so the direction of residual current was the southward mainly and 21cm/sac. The direction of tidal current at set net fishing grounds was southwesterly in ebb and westerly or northwesterly in flood, regardless of the distinction of neap and spring tide. The maximum velocity of the current in spring tide was 50cm/sec in ebb and 40cm/sec in flood and that in neap was 28cm/sec in ebb and 25cm/sec in flood. In spring tide the speed vector along the major axis of semidiurnal tide component was three times as large as diurnal tide. In neap tied, however, the speed vector was about 50% less than that in spring tied, and the semidiurnal tide and diurnal tide were equal in the size of current ellipse and the direction of major axis. The sea area had a southwesterly residual current, 11cm/sec in spring tide and 7cm/sec in neap tide.
