Studies Related To Nutrients Entering Groundwater From The Heber Valley Sewer Farm And Dairies, Roland W. Jeppson, Joan Mclean, Calvin G. Clyde, Scott Korom

Reports

Foreword: This report includes the results from a two year study in the Heber Valley to determine amounts of nutrients that are entering the groundwaters of the Heber Valley, and might ultimately enter Deer Creek Reservoir. Since Deer Creek Reservoir in Heber Valley, Utah supplies approximately 65 percent of the water distributed to Salt Lake County, the maintenance of its quality is of considerable importance. To maintain the quality of this reservoir and limit its eutrophication "best management" practices for surface water have been implemented gradually during the past decade in Heber Valley. These practices have significantly improved the qualities …

Size Classification Of Bed Sediment And Selection Of Resuspension Monitoring Sites In Upper Tampa Bay, Florida, David H. Schoellhamer, Southwest Florida Water Management District (Sfwmd), City Of Tampa, City Of St. Petersburg, Hillsborough County, Pinellas County, Tampa Port Authority

Reports

The size classification of surficial bed sediments in upper Tampa Bay, Florida, including Hillsborough Bay, Old Tampa Bay, and middle Tampa Bay south of the Interbay Peninsu la, was determined during 1987-89. Fathometer transects were performed throughout the study area to determine the reflective characteristics of the bed, and grab samples were collected to relate the fathometer data to size classifications of sediments. The data collected during this study indicate that fine bed sediments are most abundant in Hillsborough Bay and least abundant in the southern part of the study area closest to the mouth of Tampa Bay. Generally, the …

Offshore of Sandbridge Beach, Virginia, the surface of the inner continental shelf is a generally featureless, gently sloping plain, broken by several isolated sand shoals. The westernmost shoal, commonly called the Sandbridge Shoal, is located approximately 5.5 km from the shoreline in 1 O - 12 m of water. An analogous feature is located approximately 15 km northeast of the Sandbridge Shoal at depths greater than 15 m. During a pretiminary study conducted in 1987, 534 km of trackline were surveyed with acoustic subbottom and side-scan sonar systems. Geophysical data were recorded for an additional 318 km of trackline between …

Procedure For Creating Digital Baylor Coverages In Arc/Info, Gary F. Anderson, J. Berchman Smithson, Anna K. Kenne

Reports

Baylor Grounds were defined by a survey of the natural oyster beds in Virginia conducted by Lt. J.B. Baylor, USN, and completed in 1894. The original purpose of the survey was to set aside naturally productive oyster beds for protection from private leasing, which was a controversial concept at the time. Hence the commonly used term 'Baylor Grounds' is synonymous with Virginia's public oystering grounds in the present day. Other surveys, conducted later, have added to the original Baylor acreage, resulting in an estimated 243, 000 acres of public oyster grounds in Virginia. For further information on the oyster industry …

Analysis Of Mixing And Dilution Of Process Water Discharged Into The Pamunkey River, John M. Hamrick

Reports

This report describes and documents an analysis of the m1xmg and dilution· of the Chesapeake Corporation's process water discharge into the Pamunkey River at West Point, Virginia. The analysis involves the application of the Virginia Institute of Marine Science's three dimensional environmental fluid dynamics computer code, EFDC, to model the combined York, Pamunkey and Mattaponi Rivers. Following a large scale tidal calibration, the model's ability to predict the mixing of discharges into the river system is verified by the simulation of a field dye release study. The model is then used to predict mixing and dilution of the Chesapeake Corporation's …

Research Project Summaries (July 1989-December 1990), Utah Water Research Laboratory

Reports

From every side we hear of new threats to our water supply. Carcinogens, droughts, dam failures, global warming, hazardous wastes, deforestation, overpopulation, liability, and an aging infrastructure become household fears; this list grows longer and more foreboding to the average citizen. Some of these threats are real, while others are imaginary. Some we know how to overcome and others we can find ways to overcome, yet, for some, we are still helpless. The strength of a university lies in its success in stimulating inquisitive minds in critical examination of the problems of the world. People sense hope as experts find …

Draft- Nitrogen Loading And Ambient Chlorophyll-A In Hillsborough Bay (Tampa Bay), Florida: An Eutrophication Management Strategy, J.O. R. Johansson

Reports

The present report examines the past and current relationship between nitrogen loadings and ambient chlorophyll-a eutrophic subdivision of Tampa Bay (Task 1). A management strategy for eutrophication abatement, involving the reduction of present nitrogen loadings to levels which will sustain the desirable chlorophyll-a concentration and support persistent seagrass growth in the near future, is also presented for Hillsborough Bay (Task 3). The urgent need for a comprehensive long-term water quality and loading source monitoring program, specifically for Hillsborough Bay, is also discussed (Task 4).

A Survey Of Compensatory Mitigation Within The Tidal Wetlands Of Virginia, Thomas A. Barnard, Pamela Mason

Reports

This study has as its primary purpose an examination of how compensatory mitigation has worked as a wetlands management tool to date in Virginia (i.e. how well theory has been put into practice). Our approach was to look at the overall use of compensation in coastal Virginia based on regulatory records and to examine as many existing created wetlands as possible within the tidal area of the state to determine how closely these projects have come, collectively, to fulfilling the compensatory goal of wetland replacement. Secondary objectives includes an examination of the literature regarding wetland compensation concept evaluation and to …
