The river is constantly flowing so that's how material moves down the river.

Gravity, rivers flow downhill
Diffusion allows materials to move from an area of high concentration to an area of low concentration until equilibrium is reached. This process occurs passively, driven by the random movement of particles.
It splashes it waves against the rock and it takes it away to a ocean or river
Two different things that move eroded materials are water, such as rivers and streams, and wind. Water carries sediment and eroded materials downstream or deposits them along shorelines, while wind can transport smaller particles like sand and dust over long distances.
Materials move passively by diffusion from an area of higher concentration to an area of lower concentration, across the cell membrane. This process allows the substances to reach equilibrium within the cell.
