Features

  • Defines the state of water in soil and the fundamental concepts of water flow in uniform soils
  • Reviews infiltration theories including the classic Green-Ampt theory and Philip's theory
  • Describes refractional water flow in soils, preferential flows of water, and physically based hill slope hydrology
  • Discusses the effects of temperature gradients in soils and clarifies the peculiarity if thermally induced water flow
  • Explains the effects of microbiology on water flow in soils
  • Covers water flow through the soil and plant root systems and the water regimes for different varieties of vegetation
  • Explores spatial variability and field hydrogeneity of soil physical properties with reviews of the literature

    • Summary

    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.
