The Physics: As water flows downward, it exerts a drag force on particles. Because fines have a lower mass-to-surface-area ratio, the drag force can overcome gravity, suspending them or pushing them deeper into the bed. This often leads to "fines migration," where small particles clog the bottom of the filter, reducing permeability ($k$) and causing the brew to stall (Channeling).
