Oyster Spatfall In Virginia Waters: 1990 Annual Summary, Bruce J. Barber

Reports

The Virginia Institute of Marine Science (VIMS) conducts surveys ofoyster spatfall (or "setting") in Virginia waters throughout the summer reproductive period. This survey provides an estimate of the potential of a particular area for receiving a "strike" or set of oysters on the bottom and helps define the timing of setting events. Information obtained from this effort is valuable to the Virginia Marine Resources Commission (VMRC) for its shell repletion program, and to private oyster growers, both of which are interested in maximizing the timing of shell planting. In addition, by maintaining a long-term data base, trends in spatfall throughout …

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 …

Calibration Of A Parametric-Stochastic Model, Zhida Song, L. Douglas James

Reports

Conceptually, stochastic parametric modeling offers a powerful tool to select a scale for expressing catchment variability for hydrologic simulation and relating model parameters to catchment characteristics. Practically, success depends on having an efficient method for model calibration. The calibration of a stochastic model is much more difficult than a deterministic one because simulation shifts from using fixed parameters to simulate of flows as deterministic values to taking multiple combinations of paramter values randomly from distributions to simulate flows as stochastic variables. The proposed method calibrates the first two moments of each parameter distribution to represent the average and the variability …

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 …

Investigation Of Isolated Sand Shoals On The Inner Shelf Of Southern Virginia : Final Report, Suzette M. Kimball, James K. Dame, Carl H. Hobbs Iii

Reports

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 …
