Summary
Turbulent characteristics of flow velocity in a natural river were systematically analyzed in this study. Flow velocities were measured with time at six different lateral locations and at three different vertical elevations on a major navigable waterway in the United States. Analyses of the velocity data include the cross-sectional and vertical distributions of longitudinal and transverse velocity components (u, v), the fluctuating velocity components (u1, v1) and their frequency-distribution curves, turbulent intensities (�x'�y), and turbulent shear stress (scientific formula not reproduced). These analyses have shown that the strongest velocity fluctuation occurs near the main channel area above the river bed.
