摘要：

We report measurements of the interface formed when a wet front propagates in paper by imbibition and we find anomalous roughening with exponent-alpha = 0.63 +/- 0.04. We also formulate an imbibition model that agrees with the experimental morphology. The main ingredient of the model is the propagation and pinning of a self-affine interface in the presence of quenched disorder, with erosion of overhangs. By relating our model to directed percolation, we find alpha congruent-to 0.63.
