Hudak (geography and environmental science, University of North Texas) presents important concepts of groundwater hydrology with a strong emphasis on problem-solving and field applications of hydrogeology. Written for college students and environmental professionals with little or no background in hydrogeology, the text assumes that readers have a basic understanding of introductory geology or Earth science, chemistry, and algebra. This third edition features new and revised content, with a new section on the history of hydrology and discussion of recent developments in the field.
