Abstract: Flow on stepped spillways can be divided into nappe and skimming flow regimes. This technical note presents an approximate method of predicting the characteristics of skimming flow on stepped spillways. Expressing the ...

Abstract: Results are presented from an experimental investigation into the skewed three-dimensional flow around a bridge abutment. Velocity profiles on the plane of symmetry matched the standard log-law only near the bed and revealed ...

Abstract: This paper provides direct solution or iteration procedures to the following four types of submerged flow problems for rectangular sluice gates: (1) find discharge per unit width (

Abstract: This technical note presents the results of an experimental study on submerged flow over full-width sharp-crested rectangular weirs. Submerged flow was divided into impinging jet and surface flow regimes. A diagram has ...

Abstract: This paper introduces the concept of a submerged hydraulic jump being used for energy dissipation. A baffle wall is used to produce a stable deflected surface jet, thereby deflecting the high-velocity supercritical stream ...

Abstract: This technical note presents the results of a laboratory study of the transition region from the end of a hydraulic jump to fully developed open channel flow. The velocity profile changes from that of a wall jet to the ...
