iTOUGH2 is a program that provides inverse modeling capabilities for the TOUGH2 code.
While the main purpose of iTOUGH2 is to estimate two-phase hydraulic properties by
calibrating a TOUGH2 model to laboratory or field data, the information obtained by
evaluating parameter sensitivities can also be used to optimize the design of an experiment,
and to analyze the uncertainty of model predictions. iTOUGH2 has been applied to a number
of laboratory and field experiments on different scales. Three examples are discussed in this
paper, demonstrating the code's capability to support test design, data analysis, and model
predictions for a variety of TOUGH problems.
