Vertical One-Dimensional (1-D) Simulations Of Horizontal Velocity Profiles, Jerome P.Y. Maa, Jian Shen, Xiaoteng Shen, Shao Yuyang

Reports

Details of a vertical 1-D hydrodynamic model to simulate the horizontal velocity profiles for tidal estuarial flows with possible stratifications caused by salinity or Suspended Sediment Concentration (SSC) are presented. The standard 2nd order k-ε model was implemented to address the turbulent flow with possible stratification effects. Simulation results are verified with two field measurements for steady nonstratified flows and a field measurement for tidal estuary non-stratified flow. The stratification effect of salinity and suspended sediment concentration are also checked with the following descriptions: “Salinity stratification will change the typical logarithmic velocity profile to a linear profile for most of …

Metal Inventory And Fate Of Suspended Sediment In Chesapeake Bay, Maynard M. Nichols, Galen Thompson, Bruce Nelson

Reports

This report aims to provide new information that meets selected objectives of the EPA-States Taxies Plan of Action: i.e. (1) to determine the state of the Bay with respect to the distribution and concentration of selected metals in suspended material and fluid mud; (2) to establish the temooral variations of sediment and metal loading: (3) to identify potential zones of metal accumulation and trace their transport routes, and (4) to provide recommendations for monitoring contaminated sediment.

Field observations provide longitudinal coverage of the Bay with transects into Baltimore Harbor and Hampton Roads. They include contrasting conditions of seasonal high-low river …

Chesapeake Bay Bibliography - Volume V. Virginia And Maryland Waters, Marilyn Neff Loesch

Reports

The Chesapeake Bay Bibliography was initiated by the Virginia Institute of Marine Science in response to growing resource management problems of the Chesapeake Bay and its tributaries. With these problems came the realization that planning and management of such a great natural resource is an overwhelming task requiring the best available information. This bibliography, therefore, was undertaken to document existing sources of information, to help identify research and data gathering needs, and to develop a comprehensive research and information services programs for individuals interested in research on, and management of the natural resources of the Chesapeake Bay region.

An Animal-Sediment Study In The Lower York River : February 1965 To February 1966, Dexter S. Haven, John N. Kraeuter, Richarad C. Krauter, Reinaldo Morales-Alamo

Reports

Certain invertebrates are more efficient than others in filtering solids from suspension. An equal degree of variability exists among benthic invertebrates in their ability to mix biodeposits into subsurface sediments. As a result of these differences, the degree to which suspended particulate matter and associated contaminants may be deposited or mixed into sediments may in part depend on the species present, which in turn may be dependent on sediment type. A number of investigators have examined the relation between benthic animal communities and their limiting physical factors (Smith, 1932; Mare, 1942; Dexter, 1947; Holm, 1949; Stic~1ey and Stringer, 1957; Sanders, …

Sediment Mixing By Invertebrates As Shown By 85kr1, Dexter S. Haven, Reinaldo Morales-Alamo, John N. Krauter

Reports

In the event radionuclides are accidentally introduced into an estuary, many isotopes would become adsorbed on suspended particles of clay or silt; others would be incorporated into living cellular material (Caritt and Goodgal, 1954; Rice and Willis, 1959). Oysters and other filter feeders in these estuaries are capable of filtering from suspension large quantities of the suspended solids, as well as the larger living cellular material (Haven and Morales-Alamo, 1966a). Ingested material along with the associated radionuclides would be voided as compacted fecal strings or pellets (biodeposits). Many of these fecal pellets may be alternately suspended in the water mass …

Ecological Study Of The Tidal Segment Of The James River Encompassing Hog Point (Site Of The Surry Nuclear Power Station) : Completion Report, Robert A. Jordan, Patrica A. Goodwin, Charles E. Sutton

Reports

The Surry Power Station discharges cooling water into the transition zone of the James River. Phytoplankton, zooplankton, benthos, and fouling organism communities were sampled during the years 1969 through 1978, which encompassed a preoperational and an operational period. Temporal changes in the biotic communities followed seasonal patterns of temperature and salinity in the study area, and reflected inherent reproductive patterns of the organisms. Spatial patterns reflected the transport of organisms from the river in the vicinity of the intake to the zone encompassed by the discharge plume, as well as periodic bursts of meroplankton generation in the cooling water canals. …

Heavy Metal Inventory Of Suspended Sediment And Fluid Mud In Chesapeake Bay, Richard Harris, Maynard M. Nichols, Galen Thompson, John Banacki, George Vadas

Reports

Heavy metals have been found associated with suspended material, sediments and fluid mud in the Chesapeake Bay. A series of field observations were made along the Bay axis to determine the metal concentrations and their distributions at relatively high and at average river inflow between March 27-April 9 and May 2-10, 1979.

Metal concentrations in suspended material per unit volume of water relate to the concentrations of suspended material. They are higher in the zone of the turbidity maximum than landward in river water or seaward in estuarine water. Thus, metals associated with suspended material tend to accumulate in the …

An Environmental Assessment Of The Summer Plankton In The Vicinity Of The C.P. Crane Generating Station, George C. Grant, Stephen P. Berkowitz

Reports

A preliminary survey of summer plankton in ·waters surrounding the C. P. Crane generating station in Bengies, Maryland, revealed several possible effects of plant operation. These perturbations were separated into apparent small-scale and large-scale effects:

Small-scale effects were limited to the immediate discharge region of Saltpeter Creek and included (1) occasional elevation of temperatures at the surface (in August) to above the lethal limit for most zooplankton and sufficiently high to inhibit photosynthesis, (2) a decrease in chlorophyll-a, seen in July and August, (3) a sharp decrease in productivity, also in July and August, and (4) absence of a common …

Guidelines For Zooplankton Sampling In Quantitative Baseline And Monitoring Programs, Fred Jacobs, George C. Grant

Reports

Methods applicable to zooplankton sampling and analysis in quantitative baseline and monitoring surveys are evaluated and summarized. Specific recommendations by managers must take into account characteristics of the water mass under investigation, the abundance of contained zooplankton and phytoplankton populations and the objectives of the study. Realistic planning and development must also consider available monetary and manpower resources.

The sedimentary materials and bottom topography of more than 2400 square miles of the inner continental shelf floor north off the Chesapeake Bay entrance have been surveyed for potential mineral resources. Sediments consist of two principal types: (1) fine sand and (2) medium to coarse sand. The fine sand is grey-colored, subrounded, rich in quartz and relatively 11clean 11 and well sorted. The medium-coarse sand is typically iron-stained, rich in shell and poorly sorted. The fine sand covers inner parts of the shelf floor whereas medium to coarse sand covers seaward parts.
