Abstract
Experimental observations regarding mean velocity distribution, angle of flow, static pressure distribution and longitudinal turbulence intensity are all made along a typical wooden wave in the domain of ripples and dunes of river flow. The wave was produced in a low-turbulence wind tunnel and the measurements were made by hot-wire anemometry in an air medium. From these observations skin friction coefficient, form drag, and other boundary layer parameters have been evaluated to help analyze the process of sediment transport.
