We acknowledge the significant contribution of colleagues and former students at University of Québec at Chicoutimi in fracture system characterization and modeling. We thank Eric Lamontagne for his contribution to the supplement on “Effects of shear displacement on the transmissivity of a rock fracture’ included in this book. The students Mike Bellemare and Alexandre Leclerc have helped draw a number of figures. We also thank the financial institutions FAPESP, CNPq, FINEP, and CAPES that made the research of fractured aquifer possible.
