Effects of dry fractures on matrix diffusion in unsaturated fractured rocks

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...

Stress Effects on Solute Transport in Fractured rocks

Pore Connectivity, Episodic Flow, and Unsaturated Diffusion in Fractured Tuff

We use an integrated approach consisting of experiments and complementary pore-scale network modeling to investigate the occurrence of sparsely connected pore spaces in rock matrices at Yucca Mountain, Nevada, and their implications for matrix diffusion. Imbibition results indicate that pore spaces in devitrified tuff are not well-connected, and that this lack of connectivity is further compoun...

A 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...
