The understanding of fractures in hard rock is important for topics such as geomechanics, rock mechanics and groundwater flow and solute transport. One key aspect is the roughness of the fracture, often described as the joint roughness coefficient, JRC. In this paper the roughness is describing by the two parameters fractal dimension and magnitude distribution of the asperities.
