Abstract: For the hydraulic design of steep stepped channels, it is important to elucidate the aerated flow characteristics of skimming flows both in nonuniform and quasi-uniform flows. For the nonuniform aerated flow region, an analytical equation for calculation of the aerated flow depth is developed, and the surface profile and specific energy are calculated using this equation together with the continuity equation for the air phase. The results agree with the experimental data.
