Fractal Analysis of Permeability of Unsaturated Fractured Rocks
A physical conceptual model for water retention in fractured rocks is derived while taking into account the effect of pore size distribution and tortuosity of capillaries. The formula of calculating relative hydraulic conductivity of fractured rock is given based on fractal theory. It is an issue to choose an appropriate capillary pressure-saturation curve in the research of unsaturated fractur...
متن کاملA Modeling Study of Flow Diversion and Focusing in Unsaturated Fractured Rocks
Problems involving capillary barriers along sloping, layered unsaturated soils were first addressed by ZaslavThis study presents a systematic approach to analyze the flow sky and Sinai (1981a, 1981b). In the last few decades, diversion and flow focusing caused by the natural flow-barrier system several quantitative analyses of lateral water flow in in the unsaturated zone (UZ) of Yucca Mountain...

the current thesis is composed in five chapters in the following fashion: chapter two encompasses the applied framework of the project in details; the methodology of carl gustav jung to explain the process of individuation, the major archetypes and their attributes and his techniques to assess the mind’s strata are all explained. moreover, the austrian psychoanalysts, heinz kohut’s models of a...
Theoretical interpretation of a pronounced permeability scale effect in unsaturated fractured tuff
[1] Numerous single-hole and cross-hole pneumatic injection tests have been conducted in unsaturated fractured tuff at the Apache Leap Research Site (ALRS) near Superior, Arizona. Single-hole tests have yielded values of air permeability at various locations throughout the tested rock volume on a nominal scale of 1 m. Cross-hole tests have yielded equivalent air permeabilities (and air-filled p...
