Influence of flow conditions in weir model on depth of local scour

Paper presented results of investigation of formation local scour on the model of weir. Investigations were conducted on model with overflow under closure, bottom of water basins, horizontal bed protection in downstream and washing-out area. As eroded material on model sorted sand was used with d50 = 1.1 mm. Purpose of investigation were recognition variability dimension of scour during of discharge for different flow condition. Investigations showed influence depth of downstream on depth of scour, influence velocity of stream on eroded process
