''Hydrogeology: Principles and Practice'' provides a comprehensive introduction to the study of hydrogeology and the significance of groundwater in the terrestrial aquatic environment. Earlier chapters explain the fundamental physical and chemical principles of hydrogeology, and later chapters feature groundwater investigation techniques and contaminant hydrogeology. A unique feature of the book is a chapter on the application of environmental isotopes and noble gases in the interpretation of aquifer evolution. The last chapter discusses groundwater resources and environmental management, and examines the role of groundwater in integrated river basin management, including the possible impacts of climate change. Throughout the text, boxes are used to explain special topics and to illustrate international case studies.The appendices provide useful reference material and include review questions and exercises to develop the reader's knowledge and problem-solving skills in hydrogeology. This accessible textbook is essential reading for undergraduate and graduate students in earth and environmental sciences taking a course in hydrogeology or groundwater science.
