Sandy Estuarine Fill Transported Into The Mouth Of Chesapeake Bay, C. H. Hobbs Iii, S. M. Cohen, C. R. Berquist

VIMS Books and Book Chapters

The landward flux of sand into an estuary is a process that is seldom documented or quantified, yet is important to the sedimentary dynamics of a maturing estuary. Data from three recent studies converge to demonstrate the transport of sand into Chesapeake Bay from the adjacent shelf. A 100- year sediment budget, distributions of heavy minerals, and seismic-reflection data all point to the bay mouth as a gate through which a significant quantity of sand enters the estuarine system.

Man's Physical Effects On The Elizabeth River, Maynard M. Nichols, Mary M. Howard-Strobel

VIMS Books and Book Chapters

Man's ever increasing activities in the Elizabeth River, i.e. dredging, disposal of dredged material and waterfront development, have drastically altered the river floor, reshaped the shoreline and changed the circulation. Long-continued dredging of shipping channels, which is fostered by coal export, larger ships, and military needs, has moved 220 million cu yds of sediment since 1870. As a result channel depth has increased 1.8 fold, and maintenance dredging rates have doubled about every 35 years. Open water disposal released 40 million cu yds into Hampton Roads and lower Chesapeake Bay. Landfill buried tributary creeks, moved the waterfront into the river …

Trace Element Contamination From Fly Ash Sites Near Chisholm Creek, Va, George C. Grant, Bruce J. Neilson, Gene M. Silberhorn

VIMS Books and Book Chapters

The safe disposal of fly ash from power plants remains a concern because of dwindling available disposal sites and potential or actual environmental consequences. During the period from 1957 to 1974, the Virginia Electric and Power Co. station at Yorktown used a mixture of coal and refinery coke for power generation. The fly ash and bottom ash byproducts were disposed of in borrow pits which drain into Chisman Creek, a small estuary near the York River. In 1980 a domestic well near the pits turned green and tests revealed high concentrations of V and Se in some wells. Subsequently, contaminated …

Storage Efficiency Of Estuaries, Maynard M. Nichols

VIMS Books and Book Chapters

Estuaries or the U.S. Atlantic coast exhibit a range or storage efficiencies from complete storage to partial by-passing through the system. Efficiency, I.e. the ratio or sediment accumulation to river Input rate, ranges 0.7 in the Altamaha River, Ga. to 7.6 In the Choptank River, Md. Northern estuaries trap and store the bulk or their river input In addition to large amounts or sediment supplied from other sources. Southern estuaries accumulate major sediment loads in marshes and allow partial escape through channels to the sea.

The storage efficiency or difrerent estuaries is compared with respect to key factors that can …

Impacts Of Alum Sludge On Tidal Freshwater Streams, Morris H. Roberts, Robert J. Diaz

VIMS Books and Book Chapters

Alum sludge, generated in the processing of surface water .for drinking water supplies, has traditionally been discharged into nearby streams in Virginia and elsewhere. Alum sludge contains aluminum in an insoluble and non-toxic form. There remains concern, however, that alum sludge may have a negative impact on receiving waters.

Dredging And Disposal In The Chesapeake Bay, Robert J. Diaz, Robert J. Byrne, Linda C. Schaffner

VIMS Books and Book Chapters

The management questions involved in dredging and open water dredged material disposal revolve around three basic issues: 1) stability of the dredged material within the defined disposal area, 2) altered resource value of bottoms affected by dredged material, and 3) mobilization of toxins from contaminated dredged material. These issues encompass all aspects of the physical and biological character of a project site. The actual evaluation of dredging and dredged material disposal has generally concentrated on acute impacts to bottom dwelling organisms, benthos, and or to water column characteristics. This emphasis has resulted in ample evidence that many disposal practices have …
