Opis

This book outlines experimental methods and mathematical modeling appr oaches as well as cutting-edge knowledge on physical nonequilibrium ph enomena in soils. Topics include soil properties, fluid properties, me chanistic models, transfer function, geostatistics, fractal analysis, cellular-automation fluids, coupling of physical and chemical nonequil ibrium models, confirming and quantifying physical nonequilibrium in s oils, analytical solutions, field-scale research, and environmental im pacts.
