Applied hydrology is intended as an introductory textbook for courses in hydrogeology at either advanced undergraduate or dual graduate/undergraduate levels and as a reference book for the working professional. The reader is expected to have a working knowledge of college algebra; calculus is helpful, but not necessary for practical understanding of the material. A background in college chemistry is necessary to understand the chapter on water chemistry. The book stresses application of mathematics to problem solving rather than derivation of theory. To this end, you will find many example problems with step-by-step solutions. Case studies in many chapters enhance understanding of the occurrence and movement of ground water in a variety of geologic settings. The expanded appendices, which are tables of various functions and tables for unit conversions, provide additional data for solving problems in well hydraulics, water chemistry, and contaminant transport. A glossary of hydrogeological terms makes the book a valuable reference.
