Therefore, they need to be characterized for proper understanding of the system. Unfortunately, no widely accepted methodology is available to this end. In this context the objective of this thesis is three fold:  1. Define a methodology to model this type of media.  2. Explain how the explicit modeling of hydraulically dominant fracture helps in explaining scale effects.  3. Apply the methodology to two real case studies: the febex at grimsel and the ratones mine.  the thesis consists of three independent but complementary papers. They are described below.  first, i present a methodology to identify the most significant water conductive fractures. The method is based on the interpretation of cross-hole tests, and is supported by geology, geophysics and hydraulic data. This methodology has been applied to the hydrogeological characterization of a granitic block within febex experiment, switzerland. Characterising this medium starts by achieving a geometrical identification of the fractures, which demands mainly geological and geophysical data. Single borehole hydraulic tests help in neglecting those transmissive fractures, but the only means to assess the connectivity between points and the fractures extent consists of conducting cross-hole tests. The resulting geometry is later implemented into a 3d finite element mesh, where the fractures are simulated as 2d elements that are embedded into a 3d porous media that includes the effect of minor fractures. Hydraulic parameters have been obtained from the joint interpretation of cross-hole tests with 3d numerical models, using automatic calibration techniques and adjusting all the measurements simultaneously. this me<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos acad\u00e9micos de la tesis doctoral \u00ab<strong>Metodolog\u00eda para la modelacion hidrogeologica de medios
