Contaminated Sediment Transport During Floodsl, Thomas A. Fontaine
Contaminated Sediment Transport During Floodsl, Thomas A. Fontaine
US Department of Energy Publications
Over the past 48 years, operations and waste disposal activities at Oak Ridge National Laboratory have resulted in the contamination of parts of the White Oak Creek catchment. The contaminants presenting the highest risk to human health and the environment are particle reactive and are associated with the soils and sediments in the White Oak Creek drainage system. The erosion of these sediments during floods can result in the transport of contaminants both within the catchment and off-site into the Clinch River. A data collection program and a modeling investigation are being used to evaluate the probability of contaminated sediment …
Structural And Non-Structural Alternatives For Accommodating Larger Floods At Dams, Louis E. Buck
Structural And Non-Structural Alternatives For Accommodating Larger Floods At Dams, Louis E. Buck
US Department of Energy Publications
This paper provides an overview of structural and non-structural alternatives for accommodating larger floods at dams. The first two alternatives discussed, raising the height of the project and/or lowering the reservoir pool, can be used to prevent overtopping by increasing the available floodwater detention storage in the reservoir. Data gathered by an ASCE task committee survey on modifications that include increased storage by raising project height are summarized and discussed. The third alternative discussed, early warning systems, can provide a low cost alternative to structural modifications. Case studies for the warning systems at the Santee Cooper North Dam and the …

Floods are major natural hazards, not totally predictable and manageable, at least at the present time. We believe that floods, no matter how violent, need not cause major damage. Loss of lives can be prevented and economic catastrophe minimized if a decision maker has accurate prior information on major flood characteristics, such as the magnitude and arrival time of the flood and its potential damages.

Power systems often depend upon reservoir operations to generate hydropower, as well as to support thermal (nuclear and fossil) power generation. Thermal power plants frequently utilize reservoirs/rivers to provide condenser cooling water, dissipate thermal waste discharges, and/or supply safety intake water for emergency cooling systems at nuclear plants. Support of power production, however, must usually be balanced against other reservoir multiple uses such as flood control, navigation, recreation, water supplies, and environmental management.

Tailwater fisheries below hydroprojects are affected by variable flows and water quality in dam releases. The Tennessee Valley Authority (TVA) identified undesirable flow regimes, low dissolved oxygen (DO) concentrations, and undesirable temperatures as having the greatest biological impact on tailwater, and steps are being taken to mitigate impacts at numerous dams. To help evaluate mitigation efforts, an interdisciplinary team of water quality modelers, fisheries biologists, and environmental engineers developed a one-dimensional dynamic fish growth model. This model was coupled with previously developed dynamic flow and water quality models. The model results were compared to (1) fish growth data in Norris …
