内容説明
This book represents the first comprehensive reference volume available on subsurface transport and fate processes. The volume is organized into four sections covering the basics of contaminant properties and how they affect transport and fate, the fundamental processes affecting subsurface transport and fate of contaminants, applications of transport and fate information to various contaminant types, and utilization of transport and fate information for predicting contaminant behavior. Specific topics such as traditional hydrodynamic processes of advection and dispersion, facilitated transport and contaminant flushing, and individual ground water contaminants are also explored in detail. Subsurface Transport and Fate Processes is ideal for environmental and ground water consultants, regulatory agency personnel, and educators in geology, hydrogeology, civil engineering, and environmental engineering.
