Bayesian Markov-chain-Monte-Carlo (McMC) is a widely used SI strategy in hydrogeophysics (e.g., Irving and Singha, 2010; Cordua et al., 2012). Standard McMC sampling methods, however, can become computationally intractable when working with spatially distributed (high-dimensional) geophysical parameter fields.

For such situations, methods like Bayesian methods [18, 29], possibility-based methods [24, 30] and evidence-based methods [3, 2] have been suggested. Using such methods, it is possible to use samples or interval-based information to evaluate reliability.
