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.

Application of a Two-dimensional Model of Hydrodynamics and Water Quality (CE-QUAL-W2) to Cordell Hull Reservoir, Tennessee
Author: Stacy E. Howington

ISBN:
Category : CE-QUAL-W2 (Mathematical model)
Languages : en
Pages : 138
Book Description
Although not problematic within this reservoir, unacceptably low dissolved oxygen concentrations farther downstream in the system of reservoirs in the Cumberland River Basin have caused concern. This model study was undertaken to evaluate the water quality (specifically temperature and dissolved oxygen) impacts of operational changes at individual reservoir outlet structures. The study was also designed to reveal the interactions between hydrodynamics and stratification within the reservoir. Unstable stratification is thought to be responsible for additional problems in the reservoir: absence of an anticipated substantial fishery and a less than desirable amount of contact recreation. The concept of installing submerged weirs at the mouths of two of the reservoir's embayments within an established recreational site was proposed to help alleviate these 2 problems. As Cordell Hull Lock and Dam operates as a run-of-the-river navigation project on the main-stem Cumberland River, no significant operational changes at this site are possible. The reservoir is characterized by high flows, intermittent moderate to weak thermal stratification, and a relatively shallow pool. These factors combine, as was demonstrated by the model testing results, to preclude significant control over the release quality characteristics. However, the advective nature of the reservoir presents an advantage. Any changes to the quality of incoming water of Cordell Hull Reservoir will be propagated downstream, largely intact. (EDC).

Hydrodynamics and Transport for Water Quality Modeling
Author: James L. Martin
Publisher: CRC Press
ISBN: 1351439871
Category : Technology & Engineering
Languages : en
Pages : 820
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.
