Problems In Chesapeake Bay Of Mutual Interest To The State Of Maryland And The Commonwealth Of Virginia, J. Claiborne Jones, John B. Pleasants
Problems In Chesapeake Bay Of Mutual Interest To The State Of Maryland And The Commonwealth Of Virginia, J. Claiborne Jones, John B. Pleasants
Reports
The Chesapeake Bay, one of the largest and most productive estuaries in the world, represents a vast natural, economic, and social resource for the citizens of the surrounding land area. The Bay is many things to many people. Much of the economic development of the entire region has been based upon the natural transportation network and the fisheries industry provided by the Bay and its tributaries. The Bay system also offers a wide variety of water-oriented recreational opportunities, a source of water for both residential and industrial users, and a site for the final disposal of many waste products.

On Basin Hypsometry And The Morphodynamic Response Of Coastal Inlet Systems, John D. Boon Iii, Robert J. Byrne
On Basin Hypsometry And The Morphodynamic Response Of Coastal Inlet Systems, John D. Boon Iii, Robert J. Byrne
Reports
The exchange of water and entrained material between coastal basins and the inner continental shelf reduces to the problem of polarized transport (flood+, ebb-) in the conveyance channels routing flow through a coastal inlet. Here the net long-term movement of materials is largely a function of the fluid velocity and discharge~ variables whose time history at-a-station contains both periodic and aperiodic elements. In this paper the importance of the major periodic elements in coastal inlet flows and their potential contribution to the net transport of bedload materials is discussed.

A Survey Of The Late Summer Benthos Community In The Vicinity Of The C. P. Crane Generating Station, Robert A. Jordan, Charles E. Sutton, Patrica A. Goodwin
A Survey Of The Late Summer Benthos Community In The Vicinity Of The C. P. Crane Generating Station, Robert A. Jordan, Charles E. Sutton, Patrica A. Goodwin
Reports
A survey of the sediment distribution in the vicinity of the C. P. Crane Generating Station, Bengies, Maryland showed that the sediments in the creeks receiving the plant's cooling water discharge were predominantly soft clayey-silt. The benthic invertebrate taxa found in these sediments were typical of the connnunities found in oligohaline waters of Chesapeake Bay. Comparisons of the benthic community in the discharge area with the connnunities in two reference areas of similar sediment type revealed an apparent reduction in the discharge area population of the dominant amphipod, Leptocheirus plumulosus, in August.

Plant Geography And Water Quality Data For Chesapeake Bay Waters Of Virginia's Eastern Shore, John C. Munday Jr., Paul L. Zubkoff, J. Ernest Warinner Iii, Elvira Ferrez-Reyes, Hayden H. Gordon, Kenneth A. Moore
Reports
Plant geography and water quality data were collected in shallow water near Cape Charles and Occohannock Creek, Virginia on two occasions. Data from April, 1978 included hydrography, distribution and abundance of -submerged aquatic vegetation, phytoplankton census, and water clarity data. Data from May, 1978 included hydrography, phytoplankton census, water clarity, and primary productivity data. The May data collection was coincident with an overflight of the NASA JSC C-130 aircraft (6600 m) acquiring color infrared photography and multispectral scanner data; cell concentrations reached 105/ml, chlorophyll~ 72 pg/1, and suspended sediment 94 mg/1. i

Final Report On Environmental Effect Of Subaqueous Sand Fill Acquisition On The Benthic Communities Of Hampton Bar, James River, Virginia, Robert J. Diaz, Donald F. Boesch
Final Report On Environmental Effect Of Subaqueous Sand Fill Acquisition On The Benthic Communities Of Hampton Bar, James River, Virginia, Robert J. Diaz, Donald F. Boesch
Reports
The Newport News Shipbuilding and Drydock Company was granted permission to obtain sand fill from the east end of Hampton Basin Hampton Roads, Virginia for the expansion of their waterfront facilities. A clamshell dredge operated from February to July 1974 and removed a total of 597,055 cu yds of material before breaking down. In August 1974 a hydraulic dredge took over the operation and by February 1975 had removed 899,386 cu yds for total removal of 1,495,410 cu yds.
In order to assess the environmental effects of this project a program of sampling benthic organisms was undertaken from February 1974 …
Evaluation Of Salinity And Temperature As Stress Factors Affecting The Enumeration Of Fecal Coliforms By The Electrochemical Detection Method, Howard I. Kator, Martha W. Rhodes
Evaluation Of Salinity And Temperature As Stress Factors Affecting The Enumeration Of Fecal Coliforms By The Electrochemical Detection Method, Howard I. Kator, Martha W. Rhodes
Reports
The ability of an electrochemical detection method to predict viable numbers of fecal coliforms was evaluated under laboratory conditions with respect to seawater adjusted to various salinities and temperatures. The viability of an Escherchia coli isolat~ as measured by the spread plate technique utilizing non-selective media was unaffected after 12 wk exposure at 2°C and 25 °100 salinity. At higher temperatures (15-30°C) both the total decrease in cell numbers as well as the rates of die-off were greater than at 2°C. There was little apparent difference in viability across the temperature range 15-30°C. Viability was observed to be inversely related …

Demonstration Project In Low-Cost Shoreline Erosion Control : Final Report To County Administrator, County Of Accomack, Virginia, Gary L. Anderson, Robert L. Byrne, David W. Byrd, Gary M. Chianakas
Reports
·1ow cost erosion control structures were installed at ten shoreline sites located in the lower Chesapeake Bay and on the Potomac and Rappahannock Rivers to further test the applicability of the perched beach concept under diverse littoral environments. The perched beach is achieved via installation of a low sill parallel to the shoreline. The objective of the sill is to provide a partial barrier behind which an elevated (perched) beach is accreted. When successful, ~he perched beach backshore and foreshore acts to reduce the frequency of direct wave attack against the fastland and thereby reducing the erosion rate. In this …
