摘要
改进了Gao等 ( 1 994)方法 ,并用以计算潮汐汊道口门落潮干道的垂线平均流速。利用月湖潮汐汊道系统冬、夏季各一个月的潮位资料 ,计算落潮干道的潮流流速和推移质输运率。结果表明 ,流速的计算值和实测值呈良好的相关性 。
Improvements to the Gao Collins (1994) method are suggested to obtain long term depth averaged current speeds within the central ebb channel of a tidal inlet system. Two tidal water level data sets, each having a length of 29 days, were obtained from the Swan Lake Shandong Peninsula, eastern China, using a self recording tide gauge during November December 1998 and August September 1999, respectively. Using the data sets, depth averaged current speed time series are derived. The current speed data are used to calculate bedload transport rates within the central ebb channel. The result shows that the computed and observed current data sets are in good agreement and the net bedload discharge is directed to seaward in the central part of the entrance channel.
