Inverse Dual-permeability Simulations: Sensitivity Analysis

Popis výsledku v původním jazyce

The determination of hydraulic parameters for a dual-permeability medium by inverse modeling is an uneasy task. Beside the fact that the inversion of the Richards' equation is quite difficult in itself, the dual system introduces additional level of complexity. The dual-permeability forward simulator was optimized by non-linear weighted least-squares routine based on the Levenberg-Marquardt algorithm. The optimization procedure was used to minimize the discrepancies between the simulated and the measured values. The objective function formation follows identical logic as in single permeability systems. Various approaches to estimation of the volumetric proportion of the PF-domain and its permeability are demonstrated. In addition, numerical analysis ofthe effect of different interpretation of tensiometric measurements, in the context of the dual-permeability model, is presented. The uniqueness of the inverse problem and the sensitivity of the hydraulic parameters are analyzed.
