Hydraulic characteristics of the flow and sediment transport conditions are among the most important issues in design of the lateral intakes in order to minimize the flow loss. In this study, a 3D numerical model has been employed in a parametric study to study the performance of a lateral pipe intake. Observations indicated that the flow was affected by the pipe intake so that the recirculation area was close to the wall of the main channel, the wall of the lateral pipe intake and back of the lateral pipe intake. The pipe intake in vertical direction to the main channel showed the highest performance, although sedimentation behind the pipe intake in this diversion angle was higher. In addition, pipe intake showed a quite acceptable performance for almost 40% intrusion to the main channel width. Relationships for the coefficient of discharge were also developed.
