Determination of Hydraulic Parameters of Planosol Using Dual-permeability Model
Original language description
Forward and inverse modeling of water flow help to address the question of reliable hydraulic properties of natural porous medium. The soil hydraulic behavior at Valecov experimental station is closely examined. Three types of different measurements wereused to estimate soil hydraulic parameters of the heterogeneous porous system. Watermark probes and tensiometers provided soil water pressure data; Virib probes measured volumetric water content. The dual-permeability model of soil water flow was utilized to simulate the soil water dynamics in a one-dimensional vertical soil profile. The inverse modeling involved the estimation of scaling factors. Resulting sets of hydraulic parameters (scaling factors) for all sensor nests were evaluated. A similar trend in optimized hydraulic conductivity scaling factors for all three types of sensors was obtained indicating that the saturated hydraulic conductivity significantly decreases with depth in the soil profile.
