Physical and Chemical Processes of Water and Solute Transport/Retention in Soils

by H. Magdi Selim (Editor), Donald L. Sparks (Editor)

Overview

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.

Editorial Reviews

The proceedings from the October 1998 symposium in Baltimore contain eight papers discussing the physiochemical processes of water/solute transport and retention. Written by environmental scientists and engineers, the papers discuss the adsorption and capillary processes in variably saturated porous media, the transport of water and solutes in soils, solute dispersion and pore space geometry, kinematic wave solutions, tracer transport, nonlinear kinetic behavior modeling, spectroscopic methods, and molecular dynamics simulation.
