A diffusion process that obeys Fick's laws is called normal or Fickian diffusion; otherwise, it is called anomalous diffusion or non-Fickian diffusion.

Simple Fickian diffusion is a process in which the transport of the penetrant (water) is a diffusion process driven by the penetrant concentration gradient.
