Fractured Apache leap tuff: Interstitial, hydraulic, pneumatic, and thermal properties

Unsaturated fractured tuff characterization with respect to flow and transport properties presents substantial methodological and technological challenges to the scientific and engineering communities. Methods and techniques are now limited to saturated and shallow unsaturated soil media. Application of these methods and techniques to deep unsaturated fractured rock media requires that existing methods be verified, as well as the development and application of new and imaginative procedures and equipment when the existing methods are inadequate. This paper presents laboratory and field data which are used for interpreting characterization methods. Interstitial, hydraulic, pneumatic, and thermal data sets are presented over a wide range of water contents and matric suctions. 14 refs., 12 tabs
