We analyze measurements, conceptual pictures, and mathematical models of flow and
transport phenomena in fractured rock systems. Fractures and fracture networks are key …

Among the current problems that hydrogeologists face, perhaps there is none as
challenging as the characterization of fractured rock (Faybishenko and Benson 2000). This …

This paper discusses the need for a well‐considered approach to reconciling environmental
theory with observations that has clear and compelling diagnostic power. This need is well …

Heterogeneity is the single most salient feature of hydrogeology. An enormous amount of
work has been devoted during the last 30 years to addressing this issue. Our objective is to …

Two large‐scale cross‐hole pumping tests were conducted at depths of 191–226 m and 662–
706 m in deep boreholes at the Mizunami Underground Research Laboratory (MIU) …

Geology is ubiquitously heterogeneous, exhibiting both discrete and continuous spatial
variations on a multiplicity of scales. It is therefore natural to expect that hydrogeologic and …

Virtually every hydrogeologic investigation requires an estimate of hydraulic conductivity (K),
the parameter used to characterize the ease with which water flows in the subsurface. For …

Fractured rock is the host or foundation for innumerable engineered structures related to
energy, water, waste, and transportation. Characterizing, modeling, and monitoring fractured …

Hydraulic tomography has been proposed as an alternative site characterization method,
however, relatively few field scale studies have been attempted. In this paper, we …

Hydraulic tomography is a method that images the hydraulic heterogeneity of the subsurface
through the inversion of multiple pumping or cross‐hole hydraulic test data. Transient …
