Book Description
The effects of boundary geometry on internal density currents in a density stratified reservoir were investigated in a laboratory model. When water was simultaneously withdrawn and admitted to the reservoir, a complex current regime was established. The general flow pattern is described, and the influence of physical variables on the current regime is demonstrated. No analytical treatment is attempted due to the complexity of the problem.

Book Description
The effect of entering streamflow on currents of a density stratified reservoir has been studied in a laboratory model to provide insight into the prediction, control, and maintenance of quality water discharge from a thermally stratified reservoir. Twenty experiments were performed using various concentrations of a sodium chloride solution to provide a linear density stratification and using photographic techniques to provide velocity measurements of the flow field. General flow patterns are described and graphical presentation of dimensionless parameters quantitatively relate the existence, location, and magnitude of model internal density currents to entering streamflow characteristics. The applicability of the results to a prototype reservoir is discussed.

Book Description
A derivative of the Encyclopedia of Inland Waters, Lake Ecosystem Ecology examines the workings of the lake and reservoir ecosystems of our planet. Information and perspectives crucial to the understanding and management of current environmental problems are covered, such as eutrophication, acid rain and climate change. Because the articles are drawn from an encyclopedia, the articles are easily accessible to interested members of the public, such as conservationists and environmental decision makers. - Includes an up-to-date summary of global aquatic ecosystems and issues - Covers current environmental problems and management solutions - Features full-color figures and tables to support the text and aid in understanding

Book Description
The nature of flow in stratified reservoirs has been studied and a method developed, based on a laboratory model study, to predict the quality of the water discharged from the reservoir. The experimental data has been evaluated in dimensionless form, so that the results may be applied to actual reservoirs. The model was designed to simulate a relatively high head dam impounding a stratified reservoir in which the density gradient is approximately linear. The extent and magnitude of internal density currents can be determined, and the properties of the discharged water can be predicted from measurements of flow rate, density gradient, and depth. The temperature of the discharged water, effect on downstream environment, and change in the thermal structure of the reservoir are among the quantities which may be forecast. Illustrations have been provided to show the degree of control of water quality available by regulation of the reservoir water discharge.
