西江、东海水道枯水期分流比实测研究

Measurement and study of dry-period flow distribution ratio between Xijiang river and Donghai waterway

东海水道作为西江连通北江的重要河道,其与西江的分流比例多少是直接影响西北江下游地区河网径流分布的重要因素。采用水文同步实测数据,通过回归分析,计算出枯水期西江、东海水道分流比为1.92∶1。

Donghai waterway is the fiver course connecting Xijiang river to Beijiang fiver. The flow distribution ratio between Xijiang river and Donghai waterway is the key factor directly influence the runoff of river grid in the downstream reaches of xijiang and beijiang. Based on regression analysis of the synchronous measuring hydrological data, it was calculated that the flow distribution ratio between Xijiang river and Donghai waterway is 1.92：1.
