Abstract
The effect of effluent and influent seepage on the hydrodynamic forces acting on an idealized noncohesive sediment particle are investigated experimentally. The hydrodynamic conditions near and within the porous medium of the channel bed are simulated through the use of shear-velocity Reynolds number and seepage Reynolds number. Drag and lift forces on a sediment particle are measured by a force dynamometer with and without the effects of effluent or influent seepage flow. The results are presented in the form of drag and lift coefficients as functions of shear-velocity Reynolds number for different effluent or influent seepage Reynolds numbers. The effects of seepage on the dynamic forces acting on a sediment particle are analyzed in an attempt to explain the observed experimental results.
