This book attempts to combine two sepárate themes: a description of one of the links in the chain of the water cycle inside the earth´s crust, i.e., the subsurface flow, and the quantiñcation of the various types of this flow, obtained by applying the principies of fluid mechanics in porous media. The first part is the more descriptive and geological of the two. It deals with the concept of water resources, which then leads us on to other links in the cycle: rainfall, infiltration, evaporation, runoff, and surface water resources. The second part is necessary in order to quantify groundwater resources. It points the way to other applications, such as solutions to civil engineering problems, including drainage and compaction. and solutions to transpon problems in porous media, including aquifer pollution by miscible fluids, multiphase flow of immiscible fluids, and heat transfer in porous media, i.e., geothermal problems. However, the qualitative and the quantitative aspects are not treated separately but are combined and blended together, just as geology and hydrology are woven together in hydrogeology. This book is intended for engineers with a mathematical background. They will find a fairly detailed description of the physical processes occurring in porous and fractured media followed by the development of the basic flow and transport equations for both steady and transient states. Outlines are given of the methods for solving these basic equations as well as the most common analytic expressions used in handling practical problems. Basic geologic structures containing groundwater and the hydrologic processes occurring within them are described together with practical methods for measuring the relevant physical parameters of the media. We normally give orders of magnitude of these parameters for various rock types in order to provide an initial data base for solving practical problems. The International System of units (SI, i.e., metric) is used throughout. The appendix contains complete definitions and conversión factors for nonmetric units
