SEDIMENT TRANSPORT AND RIPPLES DUB TO WAVES AND CURRENTS
Coastal Engineering Proceedings, 1978 Water velocities and shear stresses have been determined for a laminar boundary layer of a progressive wave travelling over a regular series of ripples. The Lavrentiev variational method was used to transform conformally the water area with ripples into a strip with flat bottom, while the Lin approach permitted solution of the boundary layer equation ...
