Abstract: Experimental investigations of wetting front instability in porous media have been reported in the literature identifying infiltration system parameters that can contribute to the onset or persistence of fingering. These experiments have been conducted primarily in two-dimensional infiltration systems, and have produced some contradictory theories. This study provides an independent evaluation of some of these theories based on three-dimensional fingering data collected using a neutron radiography imaging system. Finger properties were determined using real-time, depth-averaged images of fingering events. The influence of initial saturation of wetting front instability was also investigated.
