The following procedure is taken to define an upscaling rule that will not only reproduce total flows at the 50 m by 50 m block scale, but also at... 

A BLOCK-SCALE STRESS-PERMEABILITY RELATIONSHIP OF A FRACTURED ROCK DETERMINED BY NUMERICAL EXPERIMENTS... 

Field observations indicate that the stress condition affects the flow characteristics of fractured rock mass (Barton et al., 1995 Ito and Hayashi, 2003 Pusch, 1989). Many laboratory investigations on single fractures also prove that the normal closure and shear dilation can significantly change the transmissivity of fractures (Makurat et al., 1990 Olsson et al., 2001). When it comes to the block scale stress-permeability relationship, the analytical models based on the orthogonal and/or persistent fracture model are available (Bai and Elsworth, 1994). However, analytical solutions do not generally exist for more realistic fracture systems. Furthermore, to the authors knowledge, block-scale study about the effect of shear dilations of fractures on the...

The DFN simulation cases were constructed to emulate the hydraulic behaviour of a typical Swedish granitic rock volume. In an earlier study (Gutters et al., 2(XX)), the geometric and hydraulic properties of the DFN model were based on the prototype repository and the TRUE Block Scale site at the Aspo Hard Rock Laboratory, Sweden. Since then, the DFN for the prototype repository was updated, Stigsson et al. (2001) carried out an extensive analysis of pump tests which has led to an improved understanding of the fracture set definition and their hydraulic properties their model was used in Gutters (2002).

Because the junctions between the coronal blocks A and the core-forming blocks B are localized at the core surface, the core blocks are stretched in the radial direction. The contribution to the free energy arising because of conformational entropy losses in the core-forming B block scales as...

The higher values of differences (2 and 3 levels) can be ascribed mainly to the resampling of the ground survey map, from its original format (i.e., aggregated at street block scale) to the square block type of satellite map. Indeed, in this step a reclassification of damage level was computed, according to the levels defined in the IKONOS-2 derived assessment...
