CREDIBILITY EVALUATION FOR PRESSURE CHANGE RATE MATCHING IN INVERSE GROUNDWATER MODELING

Abstract

Credibility evaluation index of the inverse analysis for heterogeneous hydraulic property was extended for pressure change rate matching. Numerical case study (1-d and 2-d model) and 2-d model laboratory test data were used to check the validity of the credibility evaluation index for the pressure change rate matching method. The results show that pressure change rate matching is effective when the coefficient of the pressure change rate term is adequate, and the method can be applied to the inversion for the laboratory test data which may have some model errors.
