Abstract	The previously proposed theory of bed load motion by fluid flow is developed. A plane system of equations for bed perturbations is obtained using a formula for the sediment transport rate which takes into account the effect of free-surface perturbations on sediment transport and is extended to the two-dimensional case. Dependences of the lengths and velocities of longitudinal and transverse waves with the most rapidly increasing amplitude on Froude number are determined. The effect of macroturbulent viscosity and surface waves on the generation of bed waves is determined.
