Abstract
In this study, the hydraulic characteristics at junction are studied through the variation of approaching angle, discharge in the upstream channel and the discharge ratio between the main channel and the tributary. The maximum velocity as well as the position of the maximum velocity is included in the hydraulic characteristics. The maximum velocity is increased by increasing of approaching angle, discharge in the upstream channel and the discharge ratio between the main channel and the tributary. The length from the channel junction to the point of maximum velocity is increasing by increasing of approaching angle, discharge in the upstream channel and the discharge ratio between the main channel and the tributary.
Keywords
channel junction; maximum velocity; discharge; discharge ratio; approaching angle;
