Abstract
We propose a lattice model to study the dynamics of a driven interface in a medium with random pinning forces. The critical exponents charac terizing the depinning transition are determined numerically in 1 + 1 and 2 + 1 dimensions. Our findings are compared with recent numerical and analytical results for a Langevin equation with quenched noise, wh ich is expected to be in the same universality class.
