- Abstract
A new technique for calculating turbulent aerated and nonaerated flows on spillway faces of dams and in prismatic flumes is developed and validated against field data. The technique is based on original relationships and hypotheses proposed by the author and allowing one to identify the position in a watercourse of the section where aeration appears and the section of its stabilization and to calculate, within these boundaries, the distribution of the mean velocity of liquid phase, averaged aeration factors, and the aeration depths corresponding to the conventional upper boundary of flow section with the local value of the aeration factor a loc = 0.99.
