Uniquely devoted to hard and fractured rock hydraulics‎,‎ this advanced‎-level introduction provides tools to solve practical engineering problems‎.‎ Chapter I covers the fundamentals of fractured rock hydraulics under a tensor approach‎.‎ Chapter II presents some key concepts about approximate solutions‎.‎ Chapter III discuss a few data analysis techniques applied to groundwater modeling‎.‎ Chapter IV presents unique 3D finite difference algorithms to simulate practical problems concerning the hydraulic behavior of saturated‎,‎ heterogeneous and randomly fractured rock masses without restriction to the geometry and properties of their discontinuities‎.‎ Supported by examples‎,‎ cases‎,‎ illustrations and references‎,‎ this book is intended for professionals and researchers in hydrogeology‎,‎ engineering geology‎,‎ petroleum reservoir‎,‎ rock and hydraulic engineering‎.‎ Its explanatory nature allows its use as a textbook for advanced students‎.‎
