Book Description
This manual describes the two-dimensional, laterally averaged hydrodynamic and water quality model CE-QUAL-W2 and provides guidance in its use. The model was developed primarily for use in reservoirs but has applicability to lakes, rivers, and estuaries. The manual is organized into four major parts with several appendixes. In Part I, CE-QUAL-W2 is introduced to the reader by summarizing its major usages, attributes, and historical development. Part II addresses model capabilities, assumptions, and limitations and supplies the basic information required to use the model. Part III outlines in detail the structure of CE-QUAL-W2, including the basic model equations and solution procedures. Part IV provides additional details of data assembly, presents literature values of various coefficients and constants, and discusses how to calibrate the model and interpret output. The appendixes include: Appendix A, a description of various programming aspects; Appendix B, a glossary of variables and coefficients used in CE-QUAL-W2; and Appendix C, a description of the statistical and graphics routines.

Book Description
This manual describes and provides guidance for the use of CE-QUAL-W2 V2.O, a two-dimensional, longitudinal/vertical, hydrodynamic and water quality model. The model was originally developed by the Environmental and Hydraulics laboratories, U.S. Army Engineer Waterways Experiment Station, and is suitable for applications to rivers, lakes, reservoirs, and estuaries. Version 2.0 is a result of major code modifications that have improved the mathematical description of the prototype, computational efficiency, and utility of the model. The manual is organized into three chapters and four appendixes. Chapter (1) consists of an introduction to the model and the user manual. Chapter (2) describes the model's major capabilities and limitations. Chapter (3) provides an overview of the steps involved in applying the model including data preparation and model application. The appendixes provide the user with the information necessary to understand the model details. Appendix A describes the theoretical, numerical, and computational basis for the hydrodynamic portion of the model. Appendix B describes the theoretical and computational basis for the water quality portion of the model. Appendix C describes the preparation of input files. Appendix D describes the algorithms used in the code. An index is included in Appendix E. References include a partial bibliography of CE-QUAL-W2 applications.

Book Description
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.

Book Description
This study presents an systematic approach to water quality assessment, hybrid modelling and decision support for eutrophication management in deep reservoirs. It is found that during the summer monsoon the catchment runoff into the Yongdam reservoir induces a transfer of pollutants from a middle stratified layer to the surface layer. Although the
