    Abstract: The transition from supercritical to subcritical flow in sloping channels is systematically investigated under a wide range of slopes. The hydraulic conditions for the formation of D‐jump, where the entire jump is formed on the slope, and B‐jump, where the jump is formed partly in the sloping portion and partly in the horizontal channel portion, are determined. Also, practical equations for the sequent depths and the length of the jumps are proposed. For the streamwise decay of the maximum velocity in the transition zone, the analogy with the wall jet is discussed.
