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, …


Baltimore Harbor And Channels : Surface Sediments In Virginia Channels, Robert J. Byrne, Robert J. Huggett Jan 1978

Baltimore Harbor And Channels : Surface Sediments In Virginia Channels, Robert J. Byrne, Robert J. Huggett

Reports

Bottom surface sediment samples in the Virginia Channels portion of the Baltimore Harbor and Channels Project and the four specified disposal sites were obtained and chemically analysed in accordance with DAC W31-78-C-0038. In addition, chemical analyses were performed on 15 sediment samples delivered to us from Maryland.

In total, 90 stations were occupied in Virginia Channels and the four proposed disposal sites for bottom surface sediments for bulk chemical analyses. Samples from the Maryland Channels were supplied by the Maryland Geological Survey. -

Reports

This report describes procedures and presents data concerning the concentrations of Kepone in bed sediments of the James River estuary, Virginia.


Operation Hiflow '78, Rappahannock River Estuary, Virginia, March-April 1978 : An Investigation Of Sediment Influx And Hydrodynamics, Institutions Of The Chesapeake Research Consortium And Sea Grant Programs Jan 1978

Operation Hiflow '78, Rappahannock River Estuary, Virginia, March-April 1978 : An Investigation Of Sediment Influx And Hydrodynamics, Institutions Of The Chesapeake Research Consortium And Sea Grant Programs

Reports

The prime purposes of HIFLOW 78 are to determine: 1. The response of an estuarine system to high river inflow and influx of suspended sediment. 2. The hydrodynamic interactions between a major tributary estuary and the main body of the Chesapeake Bay.
