Structure of turbulence in a non uniform sand bed channel with emphasis on the bedload transport

Abstract

The present research work experimentally investigates the effect of flow on non uniform sand bed channel morphology and corresponding turbulent flow characteristics An important parameter of sand bed channels downward seepage was considered in the present work Measures of turbulent parameters such as velocity Reynolds shear stresses thickness of roughness sub layer and shear velocities were found increasing with seepage which is responsible for increment in bed material transport An empir
