Suspended sediment concentration profiles in wave-current flows

Improved expressions to predict time-averaged and horizontally averaged ver tical suspended sediment concentration profiles ((C) over bar profiles) in wave and current (w-c) conditions are required to advance our present abili ty to predict rates of noncohesive sediment transport in the marine environ ment. In the present paper, a new expression for predicting (C) over bar pr ofiles has been calibrated and tested using measurements of waves, currents , and (C) over bar profiles obtained in a laboratory basin for a broad rang e of w-c conditions. Good agreement between observed and predicted (C) over bar profiles is demonstrated.
