【摘要】 通过在筼筜湖引水渠和出水渠断面设置流向、流速、水深等要素的测量断面,以获得筼筜湖纳潮情况下的水动力特征并由此计算筼筜湖的纳潮量和海水交换周期,在中潮条件下,筼筜湖的纳潮量为3.5×105m3,海水平均半交换周期为8.5 d.更多还原

【Abstract】 The dynamic feature of Yundang Lake was analyzed by using a set of RCM.9 current meters and tidal gauges.Based on the measured data,the volume of tidal prism in Yundang Lake is estimated as about 3.5×10~5m~3 and the half tidal exchanging-period is about 8.5 days at the middle tidal.As the tidal range becomes larger,the volume of tidal prism will become larger and the half tidal exchanging-period will be shorter.更多还原
