This paper explores the relationships between textural heterogeneity, water content distributions, and permeable pathways during steady state flow at different rates in porous media.  There are two objectives: first, to demonstrate how our concepts of spatial heterogeneity can be misleading when considering unsaturated conditions; second, to suggest that geophysics may offer unique abilities to test these evolving patterns and the underlying spatial organizations of soil hydraulic properties that they reflect.  Finally, I present an opportunity for support of hydrogeophysical research through the CUAHSI HydroGeoPhysics facility and encourage soil physicists to participate in this program.
