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
A dynamic, one-dimensional (longitudinal), water quality model for unsteady flows in rivers and streams, CE-QUAL-RIV, is presented. CE-QUAL-RIV1 is developed in two parts, hydrodynamic and water quality. Output from the hydrodynamic solution is used to drive the water quality model. The hydrodynamic code uses a four-point implicit Newton-Raphson procedure to solve the nonlinear St. Venant equation. Numerical accuracy for the advection of sharp gradients is preserved in the water quality code through the use of the explicit two-point, fourth-order accurate, Holly-Preissmann scheme. Water quality constituents include temperature, dissolved oxygen, carbonaceous biochemical oxygen demand, organic nitrogen, ammonia nitrogen, nitrate nitrogen, orthophosphate phosphorus, coliform bacteria, dissolved iron, and dissolved manganese. The effects of algae and macrophytes are also included. The model allows simulation of branched river systems with multiple hydraulic control structures, such as run-of-the-river dams, waterway locks and dams, and reregulation dams. The model was developed to simulate the transient water quality conditions associated with highly unsteady flows that can occur on regulated streams.

Book Description
This report describes the application of a two-dimensional, laterally averaged, hydrodynamic and water quality model (CE-QUAL-W2) to DeGray Lake, Arkansas. The model successfully predicted spatial and temporal variations in dissolved oxygen concentrations and other water quality variables over the stratification cycle. The application and testing of the model are described. Keywords: Reservoir stratification; Lake hydrodynamics; Computer programs; Water quality.
