Summary Report On The Calibration Of The Water Quality Models Of The Chesapeake Bay System, H. S. Chen, Paul V. Hyer, Y. Unkulvasapaul, Bruce Neilson

Reports

The intended use of the water quality model was to predict the levels of important water quality parameters. in particular the dissolved oxygen levels and the algal populations. for alternative sets of nutrient loadings. The goals of the present modelling study were to apply appropriate models to the Chesapeake Bay system. to adjust the models so that they accurately simulated conditions in the prototype and to use those models to predict conditions under a number of nutrient loading scenarios. This report provides a summary of the work done to satisfy the first two of those three objectives.

Monthly Report On The State Of Rivers 1984, Albert Kuo

Vegetative Erosion Control Project : Final Report, C. Scott Hardaway Jr., George Thomas, Andrew W. Zacherle, B. Keith Fowler

Reports

The Vegetative Erosion Control (VEC) project is a four-year study with coordinated efforts by the Virginia Soil and Water Conservation Commmission (VS&WCC) through their Shoreline Erosion Advisory Service (SEAS), the Soil Conservation Service (SCS) and the Virginia Institute of Marine Science (VIMS). Initial funding was appropriated in 1980 following the recommendation of the Coastal Erosion Abatement Commission and contracted out to the SCS and VIMS by the VS&WCC, the lead agency. (...)

The purpose of the VEC project is to supplement previous research with detailed site analysis of the early stages of marsh development and to more precisely define the …

Oyster Spatfall In Virginia Rivers: 1983 Annual Summary, James Whitcomb

Reports

The Virginia Institute of Marine Science (VIMS) conducts weekly surveys from June through early October to obtain oyster spatfall information. Spat counts are made on oyster shells strung on wire and suspended from stakes on public and private beds. The number of spat on shells are counted each week of ~:he spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period tile strikes will occur. A moderate or heavy strike on shellstrings usually indicates a significant strike on exposed bottom clutch. This is especially true for clutch planted a …

Trace Organic Analyses Of Effluent Waters From A Model Slurry Pipeline Carrying Appalachian Bituminous Coal : Final Report, P. O. Defur, W. G. Macintyre

Reports

Effluent waters from a model coal slurry pipeline have been analyzed for trace dissolved organic compounds. The model pipeline was operated under conditions simulating those proposed for a slurry pipeline from the region of Bristol to Hampton Roads, Virginia. Acidic, neutral and basic organic compounds in the separated waters were determined. Concentrations of individual compounds detected were generally less than 0.5 ppb and never exceeded 6 ppb. Adsorption experiments using coal slurry sorbents indicate that coal particles act as sorbing surfaces under coal slurry pipeline transport conditions.

A Study Of Long-Term Environmental Fluctuations In The Chesapeake Bay Region, Reidar S. Leinebo, David A. Evans

Reports

A time series of monthly mean values of temperature measurements (1952-1981) for Gloucester Point, Virginia, U.S.A. and Vardo In Northern Norway are described and the results of an eigenfunction analysis are presented. Seasonal, year-to-year and long term changes of salinlty measurements (1960-1977) for Gloucester Point and monthly mean stream-flow values (1951-1982) are also described. Commerclal Catch data from Virginia for menhaden, bluefish and Atlantic croaker shows reasonable correlation with cllmatlc changes.

The time around 1965 was a cold period with high sallnlty and low streamflow. The same period was also cold In Northern Norway (Europe). Around 1974 was a period …

Final Report To The Coastal Erosion Abatement Commission, Commonwealth Of Virginia Concerning The Inventory Of Sand Supplies In The Southern Chesapeake Bay, Carl H. Hobbs Iii, Robert J. Byrne, Robert A. Gammish

Reports

This final report to the Coastal Erosion Abatement Commission concerning the inventory of sand supplies in the southern portion of Chesapeake Bay is a continuation of the work reported on in September 1981 (Byrne et al). The report includes technical appendices in addition to the general text.
