Description/AbstractTo explore the character of underlying transport in a sandpile, we have followed the motion of tracer particles. Moments of the distribution function of the particle positions, {l_angle}{vert_bar}x(t){minus}x(0){vert_bar}{sup n}{r_angle}=D{sub 0}t{sup n{nu}(n)}, are determined as a function of the elapsed time. The numerical results show that the transport mechanism for distances less than the sandpile length is superdiffusive with an exponent {nu}(n) close to 0.75, for n{lt}1. {copyright} {ital 1999} {ital The American Physical Society}
