Produktbeschreibung

Fundamentals of Groundwater A thoroughly updated classic on the fundamentals of groundwater The second edition of Fundamentals of Groundwater delivers an expert discussion of the fundamentals of groundwater in the hydrologic cycle and applications to contemporary problems in hydrogeology. The theme of the book is groundwater, broadly defined, and it covers the theory and practice of groundwater--from basic principles of physical and chemical hydrogeology to their application in traditional and emerging areas of practice. This new edition contains extensive revisions, including new discussions of human impacts on aquifers, and strategies and concepts for sustainable development of groundwater. It also covers the theory of groundwater flow--including concepts of hydraulic head and the Darcy equation--and ground water/surface water interactions, as well as geochemistry and contamination. Readers will also find * A thorough introduction to the techniques of water resource investigations and regional groundwater flow * Comprehensive explorations of groundwater chemistry and its applications in regional characterization and assessments of health impacts * Practical discussions of groundwater contamination and water sustainability more generally * Fulsome treatments of newly emerged contaminants, like PFAS, pathogens, agricultural contaminants, methane, arsenic, uranium, and redox processes Perfect for undergraduate and graduate students taking courses in hydrogeology, groundwater, geoscience, applied geoscience, and groundwater and contaminant processes, Fundamentals of Groundwater also benefits environmental consultants, geochemists, engineers, and geologists.
