A peerless survey of the emerging field of phytoremediation Phytoremediation involves the use of vascular plants, algae, and fungi to remove and control waste or spur waste breakdown by microorganisms in the soil zone that surrounds and is influenced by the roots of plants. The diverse wastes that can be managed by using phytoremediation include xenobiotic organic chemicals, sewage, salts, nutrients, heavy metals, metalloids, and air pollutants. Phytoremediation: Transformation and Control of Contaminants provides an authoritative account of the history and the most recent developments of this exciting, emerging field. Steven McCutcheon and Jerald Schnoor’s insightful book defines the current state of the science of phytoremediation and points the way to further possible applications. Site managers and engineers will receive guidance in selecting plants to clean up contaminated sites cost effectively, while plant ecologists and biochemists will appreciate the nuts and bolts analysis of how phytoremediation works, and suggestions of directions for research. The editors divide their one-of-a-kind text into seven clearly defined sections for easy reference: *Overview of Science and Applications *Fundamentals of Phytotransformation and Control of Contaminants *Science and Practice for Aromatic, Phenolic, and Hydrocarbon Contaminants *Transformation and Control of Explosives *Fate and Control of Chlorinated Solvents and Other Halogenated Compounds *Modeling, Design, and Field-Pilot Testing *Latest Advances Environmental, remediation, and site engineers; site managers; plant and soil scientists; ecologists; and environmental toxicologists, chemists, and microbiologists will find Phytoremediation: Transformation and Control of Contaminants to be an invaluable addition to their professional libraries.

Hydrodynamics and Transport for Water Quality Modeling presents a complete overview of current methods used to describe or predict transport in aquatic systems, with special emphasis on water quality modeling. The book features detailed descriptions of each method, supported by sample applications and case studies drawn from the authors' years of experience in the field. Each chapter examines a variety of modeling approaches, from simple to complex. This unique text/reference offers a wealth of information previously unavailable from a single source. The book begins with an overview of basic principles, and an introduction to the measurement and analysis of flow. The following section focuses on rivers and streams, including model complexity and data requirements, methods for estimating mixing, hydrologic routing methods, and unsteady flow modeling. The third section considers lakes and reservoirs, and discusses stratification and temperature modeling, mixing methods, reservoir routing and water balances, and dynamic modeling using one-, two-, and three-dimensional models. The book concludes with a section on estuaries, containing topics such as origins and classification, tides, mixing methods, tidally averaged estuary models, and dynamic modeling. Over 250 figures support the text. This is a valuable guide for students and practicing modelers who do not have extensive backgrounds in fluid dynamics.

This fascinating work is divided into two main sections. Part I reviews the basic principles of water movement in channels and the mass balance approach common to most models. It also covers the practical usefulness, model peer review, and guidance on model selection and calibration. Part II discusses flow simulation and prediction of time of travel, dye tracing and mixing, heat balance and temperature modeling, and reaeration and volatilization. This interesting, easy-to-read volume includes comprehensive reviews for the use of fluorescent water tracing dyes, longitudinal dispersion, evaporation and wind speed functions, prediction of saturation concentrations of dissolved oxygen, and reaeration coefficients. This book furnishes the reader with appendices which provide a synopsis of available computer models and gives a comprehensive listing of methods used to measure flow rates in rivers, tributaries, and pipes and channels introducing wastewaters into streams. This volume is a valuable, indispensable reference for all researchers, instructors, students in advanced environmental modeling courses, and practicing engineers.
