Study on the effect of regulation project of bifurcation on flow characteristics of sink reach of river flowing into the lake
In order to research on the influence of regulation project,a two-dimensional flow mathematical model was adopted,and the change of diversion ratio,main stream line,water level,velocity of sink reach of river flowing into the lake were analyzed,the results were shown as follows:if the project built,the main stream line of bifurcation would move to the left side,and the diversion ratio of which would be increased by 0.54%.At the left side of the bifurcation,the water level would reduce obviously,and the maximum reduction of which would be 0.178m,and the velocity would increase,and maximum increase of which would be 1.0m/s.At the right side of the bifurcation,the water level would raise and the velocity would reduce,and the maximum reduction of which would be 1.667m/s.The point where water flow colliding with the left bank would change,and the velocity of point would be increased by 0.413m/s.The flow pattern would be smooth-going,the navigation condition of river would be improved,and the effect of project on flood control would be less.
