Description
The third edition provides a solid conceptual basis of the subject and introduces the quantitative relations involved in answering scientific and management questions about water resources. The text is organized around three principal themes: the basic concepts underlying the science of hydrology; the exchange of water and energy between the atmosphere and the earth’s surface; and the land phase of the hydrologic cycle. Dingman supplies the basic physical principles necessary for developing a sound, instructive sense of the way in which water moves on and through the land; in addition, he describes the assumptions behind each analytical approach and identifies the limitations of each.
Outstanding features include:
• An examination of documented trends in global change of climatic and hydrologic quantities
• Statistical and measurement methods for the development and management of hydrologic simulation modeling
• Additional exercises that emphasize analyses using data sets obtained via the Internet
• Excel spreadsheets available for download here.
“This is a great book and the new edition is a great improvement over the last. I especially liked the boxes throughout that give meaningful examples and calculations.” — Joshua Roundy, University of Kansas
“An excellent tome for environmentalists, engineers, earth scientists, and humanists. The breadth, depth, and readability of the text make the material accessible to students at a variety of levels. A gourmet menu of subject matter.” — John F. Hermance, Brown University
