heal.abstract	In this study, based on experimental evidence, the mechanical energy losses (ΔH) along two hydraulic inclined (angle φ, 0° ≤ φ ≤ 8°) jumps (d1, dm), namely the jump over a thin wall (w) and the jump over an abrupt step (w), are examined, compared and discussed, in the forms of ΔH/d1 and ΔH/H1, for a common field of w/d1 and angles φ. Two empirical equations for ΔH/d1 are presented and a number of diagrams as well, showing the differences in corresponding energy dissipation. The results of this investigation may help the hydraulic engineer when designing pertinent structures along open channel works. © 2010 Publishing House for Journal of Hydrodynamics.	en
