Abstract: The transport of spheres as a bed-load through a sparse network of immobile, bed-mounted submerged cylinders was experimentally studied to quantify how the mean velocity of the spheres in the streamwise direction is altered, ...

Abstract: The Nikuradse roughness height for a river channel or, equivalently, the friction factor (f) or Manning’s coefficient, are parameters required to calibrate hydrodynamic models used for flood risk management. In general, ...
