چکیده:

Diverted flow has been the subject of interest for researchers and hydraulic engineers for many years. In general, diversion flow can be categorized as natural and artificialflow. Natural flow diversion usually occurs as braiding or cut-off in bend rivers, while artificial flow is man-made to divert flow by lateral intake channels for water supply.This paper presents the results of a laboratory research into effect intake angle on discharge ratio in lateral intakes in 180 degree bend. Investigation on lateral intakeand determination of intake angle is among the most important issues in lateral intakeon discharge ratio with model intake angle were measured in a laboratory flume under clear-water. Experiments were conducted for various intake angles anddifferent locations with one Froude number. The results of the model study indicated that in all locations at 180 degree flume bend, increases discharge ratio occurs atangle of lateral intake of 45 degree.
