Inverse Modeling of Soil Infiltration Process

Popis výsledku v původním jazyce

This paper presents an evaluation of the soil hydraulic parameters (SHP) for a mountainous podzolic soil profile. Due to the tickness of the top-soil layer only the SHPs for the lower layers can be identified using standard approaches - a single ring (SR) infiltration experiment and a Guelph permeameter (GP) measurement. The SHPs for the top soil layer were identified here by inverse modeling of the SR infiltration process, where, especially, the initial unsteady part of the experiment can provide very useful data for evaluating the retention curve parameters and the saturated hydraulic conductivity. This inverse analysis is the main topic of this paper. Since the infiltration process is a typical case of a model that describes the progressive breakthrough of the wetting curve, we made use of adaptive domain decomposition (dd-adaptivity) for sequential activation and deactivation of the segments of our computational domain. Finally, we conducted a sensitivity analysis of our objective function on
