Transport and retention of water, nutrients, and inorganic and organic contaminants in the environment is greatly affected by physical and chemical processes in porous media such as soils. To definitively understand these processes, multiple scales--ranging from the landscape to the molecular--be investigated. Topics include fractal and spatial heterogeneity, molecular models, in situ spectroscopic and microscopic techniques, and inclusion of time-dependent phenomena in predicting solute transport/retention in soils.

During the last four decades, tremendous advances have been made towards the understanding of transport characteristics of contaminants in soils, solutes, and tracers in geological media. Transport & Fate of Chemicals in Soils: Principles & Applications offers a comprehensive treatment of the subject complete with supporting examples of mat

Soil and Water: Physical Principles and Processes describes the physical principles governing the soil-water system and particularly the sequence of processes constituting the cycle of water in the field. Organized into two parts, with a total of 11 chapters, this book first discusses the basic physical properties of both soil and water. Some chapters deal with the state of water in soil and flow of water in saturated and unsaturated soil. The second part focuses on the aspects of field water cycle, starting from the entry of water into soil to the redistribution of soil moisture. It also describes the groundwater drainage, evaporation from bare-surface soils, uptake of soil water by plants, and the water and energy balance in the field. This work is meant for students and professional workers in soil physics and other related disciplines who need or might be interested in a fundamental and up-to-date exposition of soil physics.

Emphasizing pioneering achievements, this work offers a clear and systematic description of various soil-water phenomena and their applications to soil problems such as water retention and the flux of water in soils and clays. This second edition contains material on the physical properties of adsorbed water, the application of fractal theory to solute and water flows in field soils, fingering research, and more.
