3D mathematical model of spherical particle saltatory movement in open channel with rough bed.
One of the main modes of bed load transport is saltation when particles hop up from the bed and follow ballistic-like trajectories. Mathematical models of saltation are mostly two-dimensional although the particle motion is...
