Abstract : Existing methods of designing settling basins can be divided into two groups. 1) Methods accounting only the influence of turbulence of the flow on the length of the fallout path of the particles. It is assumed that all sediment must fall out of the flow, even if in endless length. (2) Methods accounting the influence on the precipitating particles of the suspension capability of the flow. It is assumed that the flow can steadily retain in suspension a certain quantity of sediment, called the critical turbidity. The calculations of the first group is simpler (the methods of D. Sokolov, E. Zamarin, M. Velikanov, A. Zegda and others), and is implemented in the design of basins for hydro-stations, where relatively large (d > 0.25 MM.) sediment having a hydraulic size much larger than the suspension capability of the flow in the basin.
