Rainwater streaking down a vertical wall exhibited the characteristics of “fingered flow.” The wall serves as an analogy to film flow in a relatively smooth and wide aperture fracture. A digital photograph of the wall suggests that the vertical distribution of water is heavy‐tailed. A fractional‐order advection‐dispersion equation is used as a model.
