We observed and analyzed the flow of water in a shallow hillslope layer over a fragipan during and after an artificial precipitation event. Although most of the fragipan was made up of material essentially impermeable, the cracks within the fragipan carried significant portions of the interflow. Consequently, the average distance between the cracks within the fragipan is the main controlling factor in determining the subsurface flow in the shallow surface layer.
