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 Aug 1989

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 Jul 1989

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 seasons ...


A Mark-Recapture Study Of Striped Bass In The James River, Virginia : Annual Report 1988, Joseph G. Loesch, Bruce W. Hill Jun 1989

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 ...

Determination Of Marina Buffer Zones Using Simple Mixing And Transport Models : A Report To The Virginia State Dept. Of Health, Bureau Of Shellfish Sanitation As Part Of The Chesapeake Bay Initiatives Marine Pollution Abatement Initiative, John M. Hamrick, Bruce J. Neilson May 1989

Determination Of Marina Buffer Zones Using Simple Mixing And Transport Models : A Report To The Virginia State Dept. Of Health, Bureau Of Shellfish Sanitation As Part Of The Chesapeake Bay Initiatives Marine Pollution Abatement Initiative, John M. Hamrick, Bruce J. Neilson

Reports

This report describes the rationale, development and application of simple mixing and transport models for the determination of marina buffer zones and buffer zones for other point source discharges. Included in the report are two computer programs for implementation of the most general two dimensional transport model.

Zinc Distributions In Sediments, The Common Mussel, Mytilus Edulis (L.), The American Oyster, Crassostrea Virginica (Gmelin), And The Commensal Pea Crab, Pinnotheres Ostreum (Say), Cheol Mo, Bruce Neilson

Reports

Oysters and mussels of varying sizes and sediment samples were collected from oyster beds with different salinity regimes of three Virginian coastal plain rivers: Rappahannock River. James River. and Piankatank River. Zinc concentrations of 1) soft tissues. gut contents. and shells of the oysters. 2) soft tissues of the mussels. 3) pea crabs. and 4) sediment samples were measured with a flame atomic absorption (Flame AA) spectrophotometer. Particulate organic carbon and nitrogen concentrations ·of the sediments were measured with a carbon-nitrogen analyzer. The contribution of extraneous materials. such as gut contents. faeces. and pea crabs. to the variability in oyster ...

Preliminary Assessment Of Beaches And Offshore Sand Resources Of St. Eustatius, Netherlands Antilles : A Report To The Government Of St. Eustatius, John D. Boon, Robert J. Byrne, L. D. Wright, Robert A. Gammisch, Lauro Julio Calliari Jan 1989

Preliminary Assessment Of Beaches And Offshore Sand Resources Of St. Eustatius, Netherlands Antilles : A Report To The Government Of St. Eustatius, John D. Boon, Robert J. Byrne, L. D. Wright, Robert A. Gammisch, Lauro Julio Calliari

Reports

Objectives: A pilot study was undertaken in July 1988 to: 1. Provide an estimate of the location and size of offshore sand resources suitable for beach nourishment. 2. Perform beach surveys and associated sampling for determining beach equilibrium configurations. 3. Provide a preliminary assessment of sites suitable for beach enhancement. 4. Provide a preliminary assessment of areas having extraordinary environmental sensitivity. Emphasis was given.to Oranje Baai and adjoining regions.


Plume Monitoring Of Rappahannock And York Spit Channels, Baltimore Harbor And Channels: Phase Ii, York Spit Channel, M. Nichols, R. Diaz, Et Al Jan 1989

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