Subsurface Hydrology (2006)(1st ed.)(en)(488s)

George F. Pinder, Michael A. Celia9780471742432, 0471742430

With an emphasis on methodology, this reference provides a comprehensive examination of water movement as well as the movement of various pollutants in the earth’s subsurface. The multidisciplinary approach integrates earth science, fluid mechanics, mathematics, statistics, and chemistry. Ideal for both professionals and students, this is a practical guide to the practices, procedures, and rules for dealing with groundwater.
