    Designed for undergraduate and graduate students interested in learning basic soil physics and its application to environment, soil health, water quality and productivity, this book provides readers with a clear coverage of the basic principles of water and solute transport through vadose zone, the theory behind transport and step-by-step guidance on how to use current computer models in the public domain along with soil erosion and contaminant remediation. Students will develop a deeper understanding of the fundamental processes within the soil profile that control water infiltration, redistribution, evapotranspiration, drainage, and erosion. The updated second edition features one new chapter, highlighting new problems, new computer models, and remediation.


    1. Serves as the most up-to-date textbook on soil physics available
    2. Includes one new chapter and many new numerical examples
    3. Offers mathematical descriptions supported by simplified explanations
    4. Provides case studies and step-by-step guidance on how to use public domain computer models
    5. Covers all principles and processes in an easy-to-understand format with numerous illustrations and sample problems

    Students studying in the fields of Soil Science, Environment Science, Natural Resources, Agriculture Engineering, Civil Engineering, Environmental Engineering, Range Sciences, Horticulture, Crop Sciences, and Forestry, will find this book provides a solid foundation for their studies. Professionals, researchers, academicians, and companies working in fields related to Environmental Science, Soil Physics, Hydrology, and Irrigation, will find this book is a great reference tool as it is the most up to date in its field.
