In this case using two rectangular flume with 1 and 5 percent slope to production of current with different landing number in upstream of channels, double-width proportion of secondary channel to main channel, three proportion in discharge of secondary channel to total flow, and finally two total flows and connection angle of 90 degree, is considered. By comparing the result, one can find out various parameters affect on width leap and its distance of production location. In other word, when the size of total flow, proportion of secondary channel to total flow, the width proportion of main channel to secondary channel, and linear slope of two channels increases, the hydraulic jump width and its distance of production location could be increased. Generally, in 12 cases been analyzed, in some cases is noticeable, although in different cases is negligible. Also, the separation zone in all of cases could be observed. Furthermore, the FLOW3D could provide more ideal results than experimental model. Copyright@ International Science Community Association
