The scour development in time during multiple floods and equilibrium stage and the assessment of flood damage risk for bridge abutments have been investigated. The differential equation of equilibrium of the bed sediment movement for clear water conditions was used, and a method for computing scour development in time at bridge abutments during multiple floods was elaborated. The test confirmation of the methods allows us to perform computer modeling of scour processes and estimate the influence of floods with different probability, duration, frequency, and sequence on the depth of scour. The results obtained are presented.
