Diffusion in Natural Porous Media

Diffusion in Natural Porous Media - Peter Grathwohl

Diffusion in Natural Porous Media: Contaminant Transport, Sorption/Desorption and Dissolution Kinetics by Peter Grathwohl is a comprehensive and authoritative text that examines the fundamental processes controlling the movement and fate of contaminants in porous geological materials. The book systematically explores the physical and chemical mechanisms governing diffusion and advective transport in soils and aquifers, with particular emphasis on the effects of pore structure, heterogeneity, and scale on contaminant behavior. Grathwohl provides detailed treatments of sorption and desorption processes, including equilibrium and kinetic models, and discusses how these interactions influence the retardation and persistence of pollutants in natural systems. The text also addresses dissolution kinetics of non‑aqueous phase liquids (NAPLs) and their implications for long‑term contaminant release and remediation. Combining theoretical developments with experimental observations and case studies, the book offers valuable insights into modeling and predicting contaminant transport, making it an essential resource for researchers, graduate students, and environmental professionals working in hydrogeology, soil science, environmental engineering, and related fields.
