Investigating the Effect of Total Potential on Wave Velocity Changes in a 90 Degree Mild Bend

Since the main site of the reservoir dams is in the mountainous valleys, the flood resulting from it will inevitably cross the mountain paths in the case of failure of the dam. The purpose of this study is to investigate the effect of the bends on the hydraulic parameters of the unsteady flow such as velocity, depth, and dynamic pressure due to dam failures. In order to achieve this goal, a flume was built with the bends. In addition, the effects of different upstream and downstream depths flow parameters were investigated. Noticeable measured parameters were: velocity, dynamic pressure and height of the wave flood due to the dam failure in 4 angles of 0, 45, 90, and 105 degrees (straight path after the end of the bend).
