Conclusions Relation (8) was established, according to which the coefficient of aeration of a rapid uniform flow (coefficient of stabilized aeration), regardless of the roughess of the bed, is uniquely determined by the measure of the dissipation of specific energy — its gradient (I).Relation (15), being a more accurate realization than (4) of relation (8) for cross sections bounded by a conditional free surface with a local value of the water saturation coefficient $ β_{loc} $=0.01−0.02 (aloc=0.99−0.98), was developed. Relation (15) is recommended for engineering calculations in the entire practical range.The establishment of relation (8) clears up the problem of modeling the phenomenon of stabilized aeration in prismatic channels, reducing it to the condition I=idem, with simultaneous provision of the necessary path length of stabilization.Relation (6) does not correspond to the actual data on aeration of rapid flows.
