Flip buckets are usually used in high head dams to dissipate the destructive energy of high-speed jets. These structures are fixed at the ends of the outlet conduits to direct the moving jet into the atmosphere. The process of energy dissipation also resumes while the jet enters its downstream plunge pool. Although studies of flow over flip buckets date back to many years ago, there are still uncertainties regarding the flow behavior over these structures with various geometries and flow conditions. In this study, experimental measurements of static and dynamic pressures and their distribution over these structures are investigated. Measurements were made along two different simple flip buckets with various Froude numbers to determine the effects of the geometry and flow characteristics on the pressure field. Maximum pressures are also presented, and the results are compared with those of other investigations. The results of this study can be used to increase the safety of large dams that remain sustainable in the process of exploitation, such as irrigation, human consumption, industrial use, aquaculture, and navigability.
