Groundwater Science Second Edition -- winner of a 2014 Textbook Excellence Award (Texty) from The Text and Academic Authors Association -- covers groundwater s role in the hydrologic cycle and in water supply contamination and construction issues. It is a valuable resource for students and instructors in the geosciences (with focuses in hydrology hydrogeology and environmental science) and as a reference work for professional researchers. This interdisciplinary text weaves important methods and applications from the disciplines of physics chemistry mathematics geology biology and environmental science introducing you to the mathematical modeling and contaminant flow of groundwater. New to the Second Edition: New chapter on subsurface heat flow and geothermal systems Expanded content on well construction and design surface water hydrology groundwater/ surface water interaction slug tests pumping tests and mounding analysis. Updated discussions of groundwater modeling calibration parameter estimation and uncertainty Free software tools for slug test analysis pumping test analysis and aquifer modeling Lists of key terms and chapter contents at the start of each chapter Expanded end-of-chapter problems including more conceptual questions
