Numerical Simulation of the Tension Infiltration Experiment on Soil with Preferential Pathways
Original language description
Transformation of extreme rain events in the watersheds depend largely on infiltration into soil. Infiltration during extreme rain represents the near saturated water flow in the upper soil layer. It was shown in the literature that such flow may be affected by many effects, which are not conventionally considered by models nowadays. This includes slow infiltration into dry soil caused by soil repellency, the preferential flow, temporal changes of hydraulic properties due to various physical reasons (e.g. changes in volume of the entrapped air) or caused by biological processes. Relatively simple methods of measurements of effective infiltration properties of soil, accounting for the above mentioned effects, are disk tension and ring ponded infiltration experiments.
