Application of the truncated plurigaussian method to delineate hydrofacies distribution in heterogeneous aquifers

We analyze the performance of the Truncated Plurigaussian Simulation method (TPS) for the reconstruction of the internal hydrofacies architecture within large scale aquifer systems. This allows including conceptual geological information in a characterization procedure. The impact of adopting a TPS or a traditional indicator-based approach to generate multiple realizations of geo-materials distributions is assessed through numerical Monte Carlo analysis of vertically averaged hydraulic heads collected during a simulated pumping test.
