Abstract
A process was development for researching the finger dynamics using digital image analysis and the soil water content concept model. Nonuniform wetting front profile expanded vertically under the equalized potential head horizontally. Experimental data and the present concept model matched adequately. For extending the application of concept model, hysteresis models (Hogarth in 1988 and Huang in 2005) are compared. The initial temporal and spatial fingered velocity was faster with time under the same rainfall intensity, as well as fingered width. Besides, the mean fingered velocity also increase with rainfall intensity. The present concept model expounded the evolution of lingered flow and the hydraulic properties of linger dynamics successfully.
