Abstract
A new method of controlling a hydraulic jump is developed herein. Utilizing a submerged cross-jet, instead of solid chute blocks and baffle piers, to furrow and lift the supercritical approaching flow, a hydraulic jump is produced which requires a smaller tailwater depth and provides greater energy dissipation. The analytical analysis of the characteristics of the jet-forced hydraulic jump is based on the basic momentum and continuity principles and the conservation of energy. The results are verified experimentally. In the case where the jet flow is provided by the same source which provides the approaching flow, better control of the jump is expected.
