Poiseuille Flow Geometry Inferred from Velocities of Wetting Fronts in Soils

Soil structure can significantly enhance or modify infiltration rates and flow pathways in undisturbed field soils. Relations between features of soil structure and features of infiltration were elucidated from the velocities of wetting fronts. To study flow geometries during wetting, 100 sprinkler...
