Gravitational systems of groundwater flow : theory, evaluation, utilization /

This book is basically an in-depth discussion of the "unit basin" concept pioneered by Toth (emer., Univ. of Alberta, Canada) 40 years ago, a concept that many scientists were subsequently expected to learn because of its importance in the field of hydrogeology. The text is written at a relatively elementary level with minimal mathematics, making it quite readable and very accessible to the average student. Equation derivations do appear in appendixes for those interested in them, but basic mathematical principles can be found in the main body. The introduction defines the subject, and subsequent chapters discuss the unit basin concept, flow patterns that may be expected, and the significance of gravity flow of groundwater. A fifth chapter on practical applications, such as case studies, helps bring the reader to an understanding of how the theory may be applicable in the real world. This is not a first-course resource on groundwater, but it should be considered for upper-level courses after students have a basic understanding of groundwater flow. All students possessing this background knowledge will benefit from the clear presentation of the material contained in this work. Summing Up: Recommended.
