The scientific disciplines of hydrology and hydrogeology are expanding as the Earth's water is being recognized by governments and individuals as a shrinking resource—no entity can afford to take water for granted. At the present time, there is no single reference source for definitions. The Encyclopedic Dictionary of Hydrogeology is a practical, comprehensive reference guide with complete definitions of terms in hydrogeology and other fields closely related to water practices. This concise reference not only defines terms and concepts, but also provides a clear explanation of key elements so that an in-depth understanding of processes may be obtained.

• With more than 2,000 entries, from "absolute permeability" to the "Z-R relationship", this dictionary features the most up-to-date vocabulary in hydrology and hydrogeology. This dictionary would be of use to practicing scientists and professionals in all the fields of water science
• More than 340 graphs, tables and diagrams complement the entries in order to clarify terms, methods, or processes
• Essential reference for students, academics, consultants, and practitioners in hydrology, hydrogeology, environmental engineering, environmental law, and the government
