CONTRIBUTIONS OF BURST-SWEEP CYCLES TO THE REYNOLDS SHEAR STRESS OVER THE WAVEFORM STRUCTURES

ABSTRACT The purpose of the present paper is to investigate the contributions of turbulent events to the total Reynolds shear stress over artificial waveforms and to make a comparative study of turbulence between two types of isolated wave geometries: the scalene triangular shape (STS) and the isosceles triangular shape (ITS). All three components of velocity with fluctuations have been measured using 3-D Micro- Acoustic Doppler Velocimeter (ADV) at the Indian Statistical Institute's (ISI) flume, Calcutta. The motivation of this study is to determine the spatial changes of flow and turbulent events, and to gain better understanding of the physics of flow, which are responsible for the transport of sediment.
