Anotācija the main tasks for engineers. In spite of the problem importance – the scour development in time at stratified bed conditions is not studied well. The aim of the study is to propose new method and to estimate the influence of the river bed stratification on depth of scour near bridge structures in flow. The differential equation of equilibrium for bed sediment movement in clear water was used and a new calculation method for the scour development in time at vertical wall abutments in plain rivers at clear water and at stratified bed conditions with uniform grain-size sands layers was elaborated and confirmed by test results. This method allows one to calculate the scour depth in layers with different mean grain size, thickness and sequence combination
