Abstract
The well-known Edwards-Wilkinson equation with a flow term added exhib its a smoothing fixed point in addition to the normal EW fixed point. Based on this, we present a model of sandpiles involving a coupling be tween tired and mobile grains, which then shows the smoothing behaviou r that would be expected to obtain after avalanche propagation.
