Vadose Zone Journal. 8:174-176 Technical Abstract: Given the current high level of interest in the use of fractal geometry to characterize natural porous media, a special issue of the Vadose Zone Journal was organized in order to expose established fractal analysis techniques and cutting-edge new developments to a wider Earth science audience. The core papers were selected from talks and posters presented at PEDOFRACT 2007, an International Workshop on Scale Dependencies in Soil and Hydrologic Systems organized by the Fractal Applications Group from the Technical University of Madrid, Spain. The papers in this special issue utilize a variety of research methods, including fractal and multifractal characterization of experimental data, analytical, numerical and lattice Boltzmann modeling, and inverse estimation procedures. The papers are grouped according five common themes: theory development, soil fragmentation, pore space geometry, column-scale flow and transport, and field-scale flow and transport. The use of fractal geometry to characterize and model heterogeneous porous media is an extremely active area of investigation in many different disciplines. By summarizing current research on fractals in porous media, as well as introducing several novel theoretical developments, the 11 papers in this special issue should help to further advance this multidisciplinary endeavor.
