To study the characteristics of a new energy dissipator or bottom-deflection stilling basin, conjugate depths have been calculated by the fundamental theory of hydraulic jump, and an experiment has been conducted to test and optimize the jump's initial depth under the flip bucket centrifugal force and the sequent depth via the bottom deflecting arc. Calculation formulas of these two depths are presented in Newton iterative form, and optimization calculations are expressed in curves of hydraulic jump functio...
