The text is designed for advanced undergraduate or beginning graduate-level courses in hydrology, groundwater hydrology, hydrogeology, and civil engineering. This best selling text gives students a balanced examination of all facets of hydrogeology. The text stresses the application of mathematics to problem solving rather than derivation of theory. It provides a balance between physical and chemical hydrogeology. Numerous case studies cultivate student understanding of the occurrence and movement of ground water in a variety of geologic settings.
