Reports

This first volume documents the theoretical development and present state of the University of South Florida's two-dimensional, hydraulic, estuary model. It represents the accumulation of 15 years of research and development at the Civil Engineering Mathematical Modeling Center. It has been designed to be completely compatible with a host of other specialty models including a two-dimensional ecologic model, one-dimensional tributary model, salinity model, thermal model, kinetic energy model, and others. Figure 1.2 is a graphical depiction of the compatibility and functionality of various models used with the 2-D hydraulic model.

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.

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 …

Trihalomethane Compounds And Their Precursors In Salt Lake County: Evaluation Of Trihalomethane Source And Production, Kyle R. Cook, V. Dean Adams, Dennis B. George, Vincent A. Lamarra, Richard A. Hanson

Reports

Salt Lake County, Utah, watershed streams, drinking water treatment plants, and distribution systems were monitored for a period of one year or greater to determine the seasonal watershed precursor load, trihalomethane (THM) formation, and correlation between the two in the drinking water supplies. In addition, unit treatment processes were examined at Parleys, Big and Little Cottonwood water treatment plants, in the spring and late summer, to evaluate THM precursor reduction and THM formation. Additional studies were also conducted to appraise the potential contribution of natural sources to watershed THM precursor loading. Total organic carbon was used to estimate THM precursor …

A Groundwater Model Of Cache Valley, Utah, Calvin G. Clyde, Roland W. Jeppson, Win-Kai Liu

Reports

This report describes the development, calibration and use of quantitative, predictive management model for the groundwater in the Utah portion of the Cache Valley in northern Utah.

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

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 …

Oyster Spatfall In Virginia Rivers: 1983 Annual Summary, James Whitcomb

Reports

The Virginia Institute of Marine Science (VIMS) conducts weekly surveys from June through early October to obtain oyster spatfall information. Spat counts are made on oyster shells strung on wire and suspended from stakes on public and private beds. The number of spat on shells are counted each week of ~:he spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period tile strikes will occur. A moderate or heavy strike on shellstrings usually indicates a significant strike on exposed bottom clutch. This is especially true for clutch planted a …

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, …

Trace Organic Analyses Of Effluent Waters From A Model Slurry Pipeline Carrying Appalachian Bituminous Coal : Final Report, P. O. Defur, W. G. Macintyre

Reports

Effluent waters from a model coal slurry pipeline have been analyzed for trace dissolved organic compounds. The model pipeline was operated under conditions simulating those proposed for a slurry pipeline from the region of Bristol to Hampton Roads, Virginia. Acidic, neutral and basic organic compounds in the separated waters were determined. Concentrations of individual compounds detected were generally less than 0.5 ppb and never exceeded 6 ppb. Adsorption experiments using coal slurry sorbents indicate that coal particles act as sorbing surfaces under coal slurry pipeline transport conditions.

Commerclal Catch data from Virginia for menhaden, bluefish and Atlantic croaker shows reasonable correlation with cllmatlc changes.

The time around 1965 was a cold period with high sallnlty and low streamflow. The same period was also cold In Northern Norway (Europe). Around 1974 was a period …
