Prediction of forces along inclined jumps over a gradual floor rise

Abstract EN

In this investigation an effort is made to indirectly predict the dimensionless forces along inclined (angle φ, with 0˚≤φ≤8˚) hydraulic jumps over a gradual floor rise within a rectangular open channel.

A comparison of these forces is also attempted with corresponding forces from an abrupt step floor rise, a multistepped floor rise and a thin wall (plate or sill) perpendicular to the channel floor.

This indirect force prediction is based on the jumps’ water weight component along the flow, the total pressure force at both ends of the system, and the momentum changes at these ends, all combined in the onedimensional momentum equation along the flow.

The results of this study may be useful to both, hydraulic and construction engineers
