Stratification, i.e., density variations in a reservoir, occurs due to temperature variations as a result of surface heat exchange and plays an important role in determining the water quality of a reservoir. This role is determined through the influence of density variations on the movement of water in the reservoir. Therefore, the primary objective of a prediction of stratified flow hydrodynamics in reservoirs is to enable scientists to compute temperature distributions and water transports insofar as they affect various water quality parameters. One objective of the Environmental & Water Quality Operational Study (EWQOS) program of the U.S. Army Corps of Engineers is to provide District and Division offices with a tool for predicting reservoir hydrodynamics over periods of time extending from the initial setup of thermal stratification in the spring through its breakup in the fall. Such a predictive technique will subsequently be used in the prediction of water quality parameters. Both two- and three-dimensional, unsteady, variable density, heat-conducting models have been investigated during the past year. This investigation has centered around an analysis of both the mathematical and numerical bases of individual models as well as their ability to simulate a density underflow.

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.

The creation of river dams and the storage of water have been a strategy for survival for many centuries. Reservoirs have diverse functions, providing irrigation, water supply, storage of water, flood control, navigation and power generation. The silting of a reservoir is an unavoidable process. Although it cannot be halted, silting can be slowed down and controlled by a variety of soil conservation practices and by modifying agricultural practices in the catchment area. Other methods of reducing silting include the placing of certain engineering structures in the river system and the introduction of adequate strategies of reservoir operation. Silting and Desilting of Reservoirs includes aspects such as hydraulics, sediment transport, silting, sediment distribution, calculation and prediction of silting and solutions to reservoir silting.

Researchers and managers of regulated river systems will find this volume useful in acquiring information for deciding an integrated management plan for regulated river operations. Rather than the ecological theory of impacts of flow regulation, emphasis has been placed on methods to predict water quality and habitat alterations, as well as techniques to mitigate impacts from various operational scenarios. Although most chapters refer to impacts of riverine impoundments, these alternatives apply to any regulated situation in which changes in water quality or flow pattern occur. The predictive modeling techniques are explained primarily from a theoretical background. However, extensive bibliographies can guide the uninitiated to specific texts and software. Where controversial techniques have been presented, alternate methods are also described. Major topic areas include water quality problems, channel modification and management, ecological modeling and management, as well as a section on perspectives for ecological management and special problems in developing nations.

The volume starts with comparative reservoir limnology and deals with problems relating to tropical, semi-arid and temperate reservoirs. The second part concerns mathematical models of reservoirs, including new techniques for investigating their limnology. These cover physical, chemical and biological phenomena, remote sensing and the use of modelling to establish the most efficient strategy for water quality sampling. In the third, on reservoir water quality management, the potential available in fish population management for biomanipulation of reservoir water quality is introduced. Also included is a valuable section on a wide range of water quality measures, coming from the well-known Czech Hydrobiological Laboratory. Finally the editors summarise the present state of reservoir limnology. This book will be of interest to hydrobiologists and aquatic ecologists, reservoir and sanitary engineers, fisheries officers, postgraduate teaching, and the water industry dealing with drinking water supply and will provide insight into regulated rivers. It draws information from all over the world and is relevant to the whole world.
