Abstract : A method is developed for use in determining rate of sediment transportation in a layer adjacent to the ocean floor. Method is applicable only for conditions of unstable flow in this layer associated with long surface waves of small amplitude where it is assumed sediment particles in a bed are brought to a state of incipient equilibrium. By experimental determination of the distribution of lift forces and statistical analysis of turbulent fluctuations, an equation for the rate at which sediment in the bed layer is oscillated and an expression for concentration of sediment in this oscillatory state are developed. The concentration in combination with velocity distribution in bed layer associated with any incidental secondary flow can be used to calculate transport rate of bed material in direction of that flow.
