Wing dams and bridge piers are subjected to damage by floods and local scour is the main threatening factor during passage of high waters. Local scour develops as a result of transverse circulation. A method was proposed for constructing rigid guide ribs on wing dams of bridge crossings, and generalized to calculate the parameters for dams of any type, with the effect of reducing local scour by 1.5 times. The size of the ribbed box made it possible to reduce construction labor by at least 8 times. A method was also developed for calculating structures reducing erosion at concave banks and structures increasing the intensity of transverse circulation for the purpose of controlling sediment deposits.
