Description

The new edition of a bestseller, Water Flow in Soils bridges the fields of soil physics-where descriptions of water flow tend to be microscopic- and hydrology - where they tend to be macroscopic. Unlike other physics laden texts, this work conveys the fundamental concepts of water flow in soils with clear and essentially nonmathematical explanations. Using abundant illustrations, figures, and equations, the author introduces soil water flow, taking both a phenomenological and analytical approach. He elegantly elucidates the basic and advanced principles of water movement in soils.
