| Abstract | A study of the functional relationship between friction factor and the relative smoothness of the bed is made for oscillatory flow over large rippled beds. Friction factor was computed by wave height attenuation measurements in the wave flume with beds of two different sizes of ripples. Observations of particle drift at bottom and sediment suspension were al so made.
Profiles of eddy viscosity and mean concentration of suspended sediment are developed theoretically. The developed concentration profiles
confirm the observations.
The experimental results of friction factor compare well with results obtained by previous investigators, and indicate that the friction factor remains almost constant for flows where the orbital amplitude is small
and the bed ripples are large. The dominance of the eddies formed in the lees of the large ripples may be the reason for this phenomenon. |
