Abstract
We report an experimental and theoretical study of wetting front propa gation in anisotropic paper. The height-height correlation function is measured in the presence of large scale biasing and is found to scale with an exponent chi = 0.4. Theoretical analysis of this two-dimensio nal invasion predicts logarithmic scaling for isotropic paper. The obs erved nonzero roughness is due to correlated randomness and anisotropy in the paper.
