Abstract

•Discussion on the commonly accepted hypothesis behind the computation of the critical point of self-aeration in spillway flows. •Suggestion of a new formulation for the computation of the critical point of self-aeration accounting for air flow effect. •Velocity measurements are presented for the air flow over the free surface. •Spillway waves growth rate has been obtained in the non-aerated region, noticing sensitivity to the water flow boundary layer. •Entrapped air has been obtained by integrating the probability density functions of the water depth in the non-aerated region.
