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.
