[AGE29-03] Evaluate the Inversion Ability with Varied Stimuli under Different
Boundary Conditions
キーワード：Inversion, VSAFT2, change stimulus source
In the context of natural gradient, different boundary conditions are set, the laboratory sand box is filled with soil and a pumping test is performed to obtain the discharge data. After obtaining these hydrogeological parameters, the data are then combined in different combinations for back calculation, and Be verified.
Extract the data of one of the boundary conditions, add stimulus source conditions, and then perform back calculation verification with the data that has not been changed by the stimulus source.
This study carried out numerical experiments, and the experimental data were simulated using VSAFT2 and analyzed using the VSAFT2 back-calculation model. Among the 45 sets of pumping test data, the data from odd-numbered wells were selected and put into the VSAFT2 back-calculation model for back-calculation, and the monitoring data obtained from even-numbered wells was used as a verification group, and the numerical test simulation real parameter distribution field and the estimated parameter distribution were calculated. The errors and correlations of the fields, the errors and correlations between the parameter distribution fields of each back calculation.
