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.

Tidal Wetlands Of The Mattaponi River : Potential Responses Of The Vegetative Community To Increased Salinity As A Result Of Freshwater Withdrawal, Carl Hershner, Paul M. Booth, Laura R. Mitchell

Reports

The potential responses of wetland vegetation on the Mattaponi River to the proposed withdrawal of freshwater and the resulting alteration in salinity patterns were studied by comparing existing plant community distributions (which were surveyed in the summer of 1990) and historical vegetation distributions (which were evaluated through the use of aerial photography from 1953, 1971, and 1987) with estimated salinity patterns (developed from historical and adjusted freshwater inflows using a simulation model developed previously at the Virginia Institute of Marine Science).

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 …

Reports

The Virginia Institute of Marine Science, in cooperation with the Virginia Department of Conservation and Recreation, Division of Soil and Water Conservation, has identified as one of its major goals the systematic study of hydrodynamic processes that affect recreational, shoreline and benthic resources in the coastal zone of the Commonwealth. In pursuit of that goal, a long-term study of the wave climate in the Virginia portion of Chesapeake Bay was initiated in 1988 with support from the National Oceanographic and Atmospheric Administration through the Coastal Zone Management Program administered by the Virginia Council on the Environment (Grant Ho. HA88AA-D-CZ092). Past …

Geological And Benthic Evaluation Of Sand Resources In The Lower Chesapeake Bay, Report 2, Tail Of The Horseshoe : Final Report V.1, Carl C. Hobbs Iii, Linda C. Schaffner

Reports

This is the second of two reports concerning the resources of sand in the lower portions of Chesapeake Bay. The first, Geotechnical and Benthic Evaluation of Sand Resources in the Lower Chesapeake Bay (Kimball and others, 1989), presents a study of the resources in Thimble Shoal. The present work is a study of the area known as Tail of the Horseshoe which is just east of Thimble Shoal (Figure 1). The deposits of sand described in this report will be of most interest to the communities of Norfolk and Virginia Beach.

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 …

Analysis Of Organic Pollutants In Sediments And Blue Crab (Callinectes Sapidus) Tissues : Final Report To Virginia State Water Control Board, John Greaves

Reports

The Elizabeth River is a highly industrialized waterway that divides the cities of Norfolk and Portsmouth at its confluence with the lower Chesapeake Bay. It is home to the largest Naval base on the East Coast, numerous ship repair facilities, bulk and containerized cargo facilities, industrial and urban activities and wood creosoting (preserving) operations (all except one have been abandoned). This degree of industrialization has resulted in the pollution of the river, with high concentrations of polynuclear aromatic hydrocarbons (PAH, Bieri et al., 1986). A major contributor to the pollution problem has been the wood processing industry which, due to …

Dissolved Oxygen Conditions In The Machipongo River System Near Willis Wharf, Va, Bruce Neilson, Nancy Wilson

Water temperature, salinity, and dissolved oxygen concentrations were monitored at two sites in the Machipongo River system in early summer of 1989 and late summer of 1990. The two study sites have been designated as "Willis Wharf" and "Quinby." The Machipongo River system and the two sampling locations are shown in Figure 1.

Geotechnical Evaluation Of Sand Resources On The Inner Shelf Of Southern Virginia : Final Report To The City Of Virginia Beach, Suzette M. Kimball, James K. Dame

Reports

The Coastal Erosion Abatement Commission, in its report to the General Assembly (1979), recommended that "there is a need to locate sources of sand supplies for rebuilding public beaches." The Sand Resources Inventory, completed in 1982 by the College of William and Mary, Virginia Institute of Marine Science, was initiated in response to this directive. The Sand Resources Inventory, however, focused on the Chesapeake Bay. The City of Virginia Beach, facing a chronic need to renourish beaches facing the Atlantic Ocean, elected to develop an inventory of beach-quality sand reserves existing on the inner shelf of the Atlantic coast. This …

Wetlands Mitigation Evaluation Vegetation Studies : Final Report To The City Of Norfolk, Walter I. Priest Iii

Reports

Coastal wetlands in Virginia represent a finite resource which is being
subjected to ever increasing development pressures. As a means of reducing
these losses while accomodating necessary economic development, the policy
of wetlands mitigation through compensation is increasingly being utilized
by both regulatory agencies and developers. This practice generally
involves the grading of an upland area to the appropriate elevation and
planting it with wetlands vegetation to replace a mar sh being lost in
another area.

The technology to plant and grow marsh vegetation for this and other
purposes has been well demonstrated . In as few as two growing …

A Mark-Recapture Study Of Striped Bass In The James River, Virginia : Annual Report 1988, Joseph G. Loesch, Bruce W. Hill

Reports

EXECUTIVE SUMMARY

1. In the Spring 1988, 2,145 striped bass were tagged in the James River.

2. The mean size of striped bass tagged in 1988 (351.6 mm) was 117.9 mm smaller than mean size in 1987. The difference may be due to different locations and times of tagging.

3. The dominant age group in 1987 was the 1982 year class but in 1988 the dominant age group was the 1984 year class. This difference may also be accounted for by different locations and times of tagging.

4. The exodus of the mature fish out of the river after spawning …

Plume Monitoring Of Rappahannock And York Spit Channels, Baltimore Harbor And Channels: Phase Ii, York Spit Channel, M. Nichols, R. J. Diaz, Et Al

Reports

This report provides new data acquired by monitoring of hopper dredging operations at the York Spit Channel in southern Chesapeake Bay. Turbidity was measured and acoustical sensing was performed from a vessel tracking through the plumes while water samples were obtained at fixed stations for analyses of salinity and total suspended sediment concentrations. Other parameters include temperature and thickness of deposited layers. The plumes were monitored June 14, 1988 for 8.5 hours and six dredging cycles along the channel length. Most of the dredged material is silty sand. Normal background concentrations before dredging are in the range 2.6 to 17 …
