Abstract

Estimation of various flow and mass transport parameters can be seen as a problem of spatial statistics. The definition of the properties of porous and fractured media in space and time using the concept of random functions provides means for (i) studying the inherent heterogeneity, (ii) evaluating the spatiotemporal variability of the properties, and (iii) assessing the uncertainty associated with their estimated values. In this chapter, the fundamentals of stochastic subsurface hydrology are presented. Applications include mapping hydrogeological properties, flow and transport in porous and fractured media, and inverse problems.
