This paper presents the experimental campaign conducted near the Condoroma dam at 4075 m a.s.l. in an experimental setup consisting of a series of standard profile spillways with a vertical upstream face of up to five different dimensionless heights (P/Hd). The experimental results indicate that for all P/Hd ratios studied, the discharge coefficients adjusted to the Condoroma altitude are lower than those reported by classical formulations used in conventional spillway design. As a result, a generalized equation is proposed to estimate the discharge coefficient for standard spillways located in dams at similar elevations above sea level.

Comment: A scientific article that helps expand the frontiers of knowledge, leaves us with a contribution between the variation of the discharge coefficient due to atmospheric pressure at a height of 4075 m.a.s.l. where the flow profile is between the geometry of the landfill and the atmospheric pressure. causing the flow profile to vary with respect to the equations developed at lower altitudes.
