Wetlands Evaluation And Management In Virginia, Eileen L. Shea, N. Bartlett Theberge

Reports

Complex biotic communities which have lately been recognized as being of vital importance to aquatic and upland ecosystems have evolved at Virginia's land-water interface. Most obvious are the beaches and vast intertidal stands of halophytic (salt-tolerant) plants on the periphery of the Atlantic Ocean, Chesapeake Bay and their subordinate estuaries. Less obvious, but no less important, are nonvegetated intertidal flats and coastal freshwater marshes. Inland swamps and freshwater marshes complete the inventory; though more limited in extent than their coastal analog. Complex biotic communities which have lately been recognized as being of vital importance to aquatic and upland ecosystems have …

Hydrography And Hydrodynamics Of Virginia Estuaries. Xvii, Mathematical Ecosystem Modeling Study Of The York River, P. V. Hyer, A. Y. Kuo, C. S. Fang, W. J. Hargis Jr.

Reports

The York River drainage basin is rural, with an economy based on farming, logging, fishing and recreation. Water quality conditions are generally good, with low chlorophyll and nutrients and low fecal coliform counts. Dissolved oxygen concentrations are high except for periodic deoxygenation of the water deeper than 8 m in the reach extending 10 km upstream of the mouth.

A quasi-three dimensional tidal average model was constructed and calibrated using intensive field data collected in June and July, 1976 and verified using slack water run data from September, 1976. The model components are: salinity, fecal coliform, chlorophyll, CBOD, dissolved oxygen, …

Disinfection Efficiency And Relative Toxicity Of Chlorine And Bromine Chloride: A Pilot Plant Study In An Estuarine Environment, Norman E. Leblanc, Morris H. Roberts

Reports

The present study was conducted by the Virginia Interagency Task Force on Chlorine to compare the relative merits of bromine chloride and chlorine as wastewater disinfectants. Operational and disinfection qualities of both halogens and the relative toxicities of the treated effluents were studied in a pilot scale system. Three specific objectives were pursued; 1. an evaluation of the relative disinfection capabilities of the two halogens; 2. an assessment of the toxicity of each effluent stream to juvenile spot; and 3. an analysis of the halogenated organics produced in treated and disinfected effluent. The results of studies directed at the first …

Report Of The National Blue Crab Industry Workshop: September 10-11, 1977 Charleston, South Carolina, Raymond J. Rhodes, W. A. Van Engel

Reports

The National Blue Crab Industry Workshop was held on September 10-11, 1977 at the South Carolina Marine Resources Center of the South Carolina Wildlife and Marine Resources Department in Charleston, South Carolina. The workshop was organized to address the blue crab industry's major problem areas and stimulate innovative thinking for improving productivity. The problems faced by the blue crab industry are not necessarily unique compared to other food industries; consequently, methodology to mitigate these problems will probably be transferred from other industries. Much of what was discussed in the technology corrnnittees has been faced by other industries, although recent food …

Summary Of The Hampton Roads 208 Water Quality Modelling Studies, Bruce J. Neilson

Reports

The purpose of· the Hampton Roads 208 Study is to assess the present and future water quality conditions in the study area and to develop a wastewater management plan to achieve certain water quality goals. The study included all major estuaries in the area and, among other thing·s, took account of population and industrial growth, effluent quality {as mandated by PL92-500) and nonpoint sources of pollution. Land use maps for 1976, estimates of future land use, population projections and many other elements of the study initiated in 1974 provided the foundation upon which the water quality work was based. Projections …

Harmonic Analysis And Tidal Prediction By The Method Of Least Squares: A User's Manual, John D. Boon, Kevin P. Kiley

Reports

A common objective in the treatment of measured tides is the mathematical separation by harmonic analysis of certain periodic components which can be used to simulate the astronomical tide. Traditionally, astronomical or predicted tides have been represented by the sum of several such components, each one due to a particular aspect of the tide-producing forces. Once determined, the same set of parameters governing each periodic component may be used to predict the tide during any desired time period at a given location. These parameters are known as the tidal constants for that location. Although a number of different methods have …
