Beach Erosion And Accretion At Virginia Beach, Victor Goldsmith, Susan C. Strum, George R. Thomas, Coastal Engineering Research Center (U. S. )

Reports

This report is published to provide coastal engineers with a description of beach erosion and accretion at Virginia Beach, Virginia, including the effect of continuing beach replenishment, and the apparent unimportance of land use in determining erosion. This report also provides bench-mark data on coastal processes at the shore north of the CERC Field Research Facility at Duck, North Carolina. The work was carried out under the beach evaluation program of the U.S. Army Coastal Engineering Research Center (CERC).

Recent History And Response Characteristics Of Wachapreague Inlet, Virginia : Final Report, Robert J. Byrne, Joseph T. Dealteris, Jerome P. Sovich

Reports

Wachapreague Inlet, a large downdrift offset inlet in the barrier island complex of the mid-Atlantic coast (Delmarva peninsula), was studied during the period 1971-1974. The inlet channel width is bout 500 m and the throat cross-sectional is about 4,500 m2 • The inlet channel is about 3 km in length, approximately one-half of which is within the well-developed horseshoe shaped ebb delta complex. The maximum channel depth is 20 rn which occurs at the throat. Elements of the study included: (1) the inlet morphornetric history (120 years), (2) assessment of surficial and sub-bottom sediments within the inlet complex, (3) determination …

Assessment Of Mechanical Damage To Entrained Ichthyoplankton, Vepco Surry Nuclear Power Station, J. V. Merriner, A. D. Estes

Reports

Thermal plume ichthyopla~kton sampling during November and December 1976 was cancelled since Units 1 and 2 of VEPCO Surry Nuclear Power Station were non-operational due to refueling. In lieu of the thermal plume ichthyoplankton entrainment program, a sampling program to estimate mortality from mechanical damage was initiated.

Four sampling sites were selected for determination of quantity and condition of organisms entering and leaving the plant. Sites were selected at points preceding and following critical areas where the likelihood of damage was greatest. Net .sets were made using a 0.5 meter paired net apparatus. All sets were at bottom strata to …

Characterization Of A Historically Nutrient Enriched Marsh Ecosystem : Yorktown Creek, Yorktown, Virginia, R. L. Wetzel, M. S. Kowalski, W. M. Rizzo, A. Thompson, K. L. Webb

Reports

In this report, we summarize our initial findings of a nutrient enriched aquatic ecosystem prior to relaxation of sewage input. The studies reported were directed toward characterizing the system prior to relaxation and to begin 􀌣xperimental studies to accomplish our general objectives.

Environmental Effects Of James River Sewage Treatment Plant Outfall Construction, Dexter S. Haven, Paul C. Kendall, Robert J. Diaz, Donald F. Boesch, Michael E. Bender

Reports

In the spring of 1975 the Institute began a program to determine whether significant environmental changes would occur in the area of the new James River Plant outfall that might be related to its construction and/or initial operation. Parameters measured in the study were benthic animal and oyster populations, coliform levels and chlorine residuals. The primary emphasis of the study centered on the estimation of the impact of the construction activity on shellfish beds in the area. The results of the investigation are presented in three segments, the first dealing with shellfish populations, the second with other benthic animals and …

Task 1 Evaluation On The Thickness Of The Mobile Surface Layer, Dam Neck, Virginia : Final Report To Malcolm Pirnie Engineers, Inc., John D. Boon

Reports

Our objective under Task 1 was to make an assessment of the sedimentary features (sediment texture and structures) present in cores (obtained by vibratory method) at the project site in order to express an opinion as to the thickness of the "surface mobile sand layer". The mobile sand layer is that surficial sediment layer undergoing cut and fill episodes due to present day wave and current induced sediment transport. In addition, this report contains information extracted from existing literature on recent (1859 to 1968) shoreline behavior in the vicinity of the proposed outfall and on some aspects of surface sediment …

Ecological Effects Of Highways On Coastal Wetlands, Atlantic Coast Region, John D. Boon, George M. Dawes

Reports

A literature review of past and on-going research and activities of the principal investigators is the basis for evaluating environmental effects of highways in wetlands. Values of wetl8,$1ds are discussed briefly. Physical. biological and chemical impacts are associated with highway construction. operation and maintenance. Environmental impacts are scaled in terms of magnitude and duration and mitigating measures are identified. The foregoing are summarized in matrices. The report further identifies further research which is needed to design highway projects with environmental aspects in mind.

The Effect Of The Chesapeake Corporation On The Water Quality Of The Upper York River With Respect To Total And Fecal Coliforms And Fecal Streptococci, Martha Rhodes, Howard Kator, Nancy King

Reports

Levels of total and fecal coliforms and fecal streptococci in the Mattaponi, Pamunkey and York Rivers were monitored for one year in the vicinity of the town of West Point, Virginia. These parameters were also determined for selected process waste waters and effluents from the Chesapeake Corporation, West Point, Virginia.
