Název v původním jazyce

Impact of Using CT Imaging on Estimation of Soil Hydraulic Properties by Inverse Modeling

Popis výsledku v původním jazyce

A laboratory infiltration-outflow experiment with automated data acquisition performed on an undisturbed soil column was developed. Data sets gained in this experiment were used as an input for the estimation of the soil hydraulic properties by means ofinverse modeling. The S_1D_DUAL code, as a one dimensional dual-permeability forward simulator, was coupled with the parameter estimator for non-linear optimization. The hydraulic parameters were optimized in least-square sense. Scaling factors of watercontent and hydraulic conductivity were included on the basis of the 3D CT image analysis into the model input files. Significant improvement of the model prediction was reached by including any CT imaging information.
