Summary Report On The Calibration Of The Water Quality Models Of The Chesapeake Bay System, H. S. Chen, Paul V. Hyer, Y. Unkulvasapaul, Bruce Neilson Mar 1984

Summary Report On The Calibration Of The Water Quality Models Of The Chesapeake Bay System, H. S. Chen, Paul V. Hyer, Y. Unkulvasapaul, Bruce Neilson

Reports

The intended use of the water quality model was to predict the levels of important water quality parameters. in particular the dissolved oxygen levels and the algal populations. for alternative sets of nutrient loadings. The goals of the present modelling study were to apply appropriate models to the Chesapeake Bay system. to adjust the models so that they accurately simulated conditions in the prototype and to use those models to predict conditions under a number of nutrient loading scenarios. This report provides a summary of the work done to satisfy the first two of those three objectives.

New Concepts For Preliminary Hydropower Design: The Powermax Slope, Binary Turbine Sizing, And Static Regain, Frank W. Haws, Eugene K. Israelsen Jan 1984

New Concepts For Preliminary Hydropower Design: The Powermax Slope, Binary Turbine Sizing, And Static Regain, Frank W. Haws, Eugene K. Israelsen

Reports

In Utah during the 1960s, the cost of producing electrical energy was as much, or in some cases more, by hydroelectric generation than by plants using steam from coal fired boilers. The relatively high hydropower cost was generally attributed to maintenance and replacement costs associated with plants that had been build in the 1920s. Utah Power & Light Company during the 1960 period decided not to renew power licenses and to abandon many small hdyroplants. Since 1973, rising coal and related fossil fuel costs have caused steam generation costs to accelerate and have made hydroelectric generation relatively more attractive. However, …

Direct Filtration Versus Conventional Water Treatment In The Intermountain Region, Susan K. Burns, V. Dean Adams, Steel B. Maloney

Reports

The direct filtration water treatment scheme does not include sedimentation and in some cases flocculation. Compared to conventional treatment, direct filtration has lowered capital costs, reduced space requirements, decreased sludge quantities, and reduced coagulant dosages. One objective of this research was the statistical comparison of the direct filtration, Utah Valley Water Purification Plant (Orem, Utah) and the conventional Little Cottonwood Water Treatment Plant (Salt Lake City, Utah). These treatment plants are the two most compatible treatment plants having the highest correlation of source water in the local area. The Little Cottonwood plant receives approximately 65 percent of its sources water …


Sediment-Phosphorus Relationships In Deer Creek Reservoir, Jay J. Messer, Thomas B. Hardy, Jean M. Ihnat Jan 1984

Sediment-Phosphorus Relationships In Deer Creek Reservoir, Jay J. Messer, Thomas B. Hardy, Jean M. Ihnat

Reports

Summary and Conclusions: Laboratory analyses of sediment samples recovered from Deer Creek Reservoir showed the sediments to have amoderate potential for serving as a source of phosphorus (P) for the overlying water solumn under anaerobic conditions. This source could account for the occurrence or exacerbation of blue-green algal blooms in the upper end of the reservoir when the sediment surface becomes anaerobic late in the summer. It could also delay the response of the reservoir to programs that decrease external P loading, if the upper end of the reservoir still has large enough algal blooms to render the sediment-water interface …

Management Of Groundwater Recharge Areas In The Mouth Of Weber Canyon, Calvin G. Clyde, Christopher J. Duffy, Edward P. Fisk, Daniel H. Hoggan, David E. Hansen

Reports

Proper management of surface and groundwater resources is important for their prolonged and a beneficial use. Within the Weber Delta area there has existed a continual decline in the piezometric surface of the deep confined aquifer over the last 40 years. This decline ranges from approximately 20 feet along the eastern shore of the Great Salt Lake to 50 feet along in the vicinity of Hill Air Force Base. Declines in the piezometric surface are undesirable because of the increased well installation costs, increased pumping costs, decreased aquifer storage, increased risk of salt water intrusion, and the possibility of land …

Non-Linear Oscillation, Automodulation And Anelasticity, Tetsuro Suzuki, Manfred Wuttig Jan 1984

Non-Linear Oscillation, Automodulation And Anelasticity, Tetsuro Suzuki, Manfred Wuttig

Physics Faculty Research & Creative Works

The auto modulation observed in the course of internal friction is discussed as a special example of the universal nature of non-linear oscillations. Universal features of non-linear oscillations are the requirement of energy supply or negative damping and the period doubling route to chaos. The negative damping responsible for the auto modulation is described in terms of the soliton model for twinning deformation. © 1984 The Japan Society of Applied Physics.

Late Cenozoic Landforms, Stratigraphy And History Of Sea Level Oscillations Of Southeastern Virginia And Northeastern North Carolina, Pamela Crowson Peebles

Dissertations, Theses, and Masters Projects

A depositional model accounting for the stratigraphic sequences which accumulate during a marine transgression across a dissected coastal plain aids in understanding the geologic history of southeastern Virginia and northeastern North Carolina. Application of this model to the Shirley Formation (middle Pleistocene) and the Sedgefield and Lynnhaven members of the Tabb Formation (late Pleistocene) allows delineation of (1) the facies within, (2) the areal extent of, and (3) the landforms associated with these lithostratigraphic units. Facies within each lithostratigraphic unit consist of (1) a vertical succession from local, basal, channel-fill deposits and coarse, basal, lag deposits which grade upward into …
