文摘The circumfluence around the Jiuduan Sandbank is thoroughly studied by means of the principle of least resistance in fluid dynamics. The diversion ratio of the North Channel for 1998 is calculated, which is almost the same as the field survey data. The normal and minimum diversion ratios of the North Channel after stages I , II and III regulation works as well as the future phase are obtained. The numerical results and predicted value are accurate.
