Recent numerical results for a model describing dispersive transport in ricepiles are explained by mapping the model to the depinning transition of an elastic interface that is dragged at one end through a random medium. The average velocity of transport vanishes with system size L as 〈v〉~L^2-D~L^-0.23, and the avalanche size distribution exponent τ0ex0ex=0ex0ex2-1/D1.55, where D2.23 from interface depinning. We conjecture that the purely deterministic Burridge-Knopoff ``train'' model for earthquakes is in the same universality class.
