Paper presented analysis results of investigations of influence scale model on formation of scour in time. Investigations were conducted on two model this same taired constructions with the over of water under the closure, bottom of water basins and washing-out area. Models were made in two skales 1:30 and 1:55. In investigations were used this same eroded material on two models - sand. Estimated change of parameter for morfological time scale between two models of the dam. In Froudian models with a nonlinearly scaled size of sand grains the maximum depth of local scour develop slower than their linear counterparts in prototypes, except for the initial stage of scour
