AB: We discuss a random domain decomposition approach to analyze flow and transport in highly heterogeneous, composite porous media that greatly improves estimates of pressure head statistics. Composite porous media consist of distinct geologic facies. Within a composite medium, hydraulic conductivity and other relevant flow and transport parameters can be represented through a pair of random processes: i) a boundary process that determines facies arrangement and extent and ii) a random process that defines parameters within a given facies. Our primary focus is on efficient use of data to provide a probabilistic description of large-scale boundary processes.
