![]() ![]() ![]() High values of RSS in the outer region relate to higher momentum flux, eroding the outer bend. From the distribution of Reynolds shear stress (RSS), the transverse or radial motion of the sediment across the bend was identified. A laboratory investigation was conducted in a sinuous rectangular alluvial channel with rigid sides and movable uniform sand bed. ![]() ![]() This experimental study is intended to report near-bed hydrodynamics and morphological characteristics under the impact of downward seepage. The presence of a small seepage velocity in streams and rivers induces transfer of mass and momentum near the sediment boundary, causing bank failure and instability of hydraulic structures.
