Effects of simulated ground-water pumping and recharge on ground-water flow in Cape Cod, Martha's Vineyard, and Nantucket Island basins, Massachusetts
John P. Masterson, Paul M. Barlow
1997, Water Supply Paper 2447
Three-dimensional transient ground-water-flow models that simulate both freshwater and saltwater flow were developed for the flow cells of the Cape Cod Basin to determine the effects of long-term pumping and recharge, seasonal fluctuations in pumping and recharge, and prolonged reductions of natural recharge, on the position of the freshwater-saltwater interface,...

Thomas G. Huntington, R. P. Hooper
1997, Conference Paper, Proceedings of the 1997 Georgia Water Resources Conference : March 20-22, 1997, Athens, Georgia
Biogeochemical studies at the Panola Mountain Research Watershed near Atlanta, Ga., and in the Coastal Plain Province of Georgia have provided an assessment of some of the potential effects of acid deposition on streamwater quality and forest health in Georgia. Historically, "acid rain" has not been considered a potentially serious...
Use of particle tracking to improve numerical model calibration and to analyze ground-water flow and contaminant migration, Massachusetts Military Reservation, western Cape Cod, Massachusetts
John P. Masterson, Donald A. Walter, Jennifer G. Savoie
1997, Water Supply Paper 2482
A steady-state, three-dimensional flow model coupled with a particle-tracking algorithm was developed to assess the complex interaction of hydrogeologic conditions affecting ground-water flow and contaminant transport--including aquifer heterogeneities, hydrologic boundaries such as ponds and streams, ground-water withdrawals, and aquifer recharge to characterize the migration of contaminants emanating from beneath the...
Hydrogeologic framework of western Cape Cod, Massachusetts
John P. Masterson, Byron D. Stone, Donald A. Walter, Jennifer G. Savoie
1997, Hydrologic Atlas 741
The aquifer of western Cape Cod consists of several hydrogeologic units composed of sand, gravel, silt, and clay (fig. 1) that were deposited during the late Wisconsinan glaciation of New England. The aquifer is a shallow, unconfined hydrologic system in which ground-water flows radially outward from the apex of the...
Hydrogeology and analysis of ground-water-flow system, Sagamore Marsh area, southeastern Massachusetts
Donald A. Walter, John P. Masterson, Paul M. Barlow
1996, Water-Resources Investigations Report 96-4200
A study of the hydrogeology and an analysis of the ground-water-flow system near Sagamore Marsh, southeastern Massachusetts, was undertaken to improve the understanding of the current (1994­ 95) hydrogeologic conditions near the marsh and how the ground-water system might respond to proposed changes in the tidal-stage regime of streams that...
Small watershed studies: Analytical approaches for understanding ecosystem response to environmental change
Thomas G. Huntington, R. P. Hooper, Peter S. Murdoch
1996, Conference Paper, Proceedings of the Watershed '96 Conference--Moving ahead together
Biogeochemical studies in small watersheds provide an analytical approach to understand how ecosystems respond to natural climatic variations and human-induced environmental change. Small watersheds, usually less than 5 km2, are small enough to permit characterization and understanding of ecosystem processes within relatively simple, homogeneous biological and physical settings; yet they are large enough to...
Predicting watershed acidification under alternate rainfall conditions
Thomas G. Huntington
1996, Water, Air, & Soil Pollution (90) 429-450
The effect of alternate rainfall scenarios on acidification of a forested watershed subjected to chronic acidic deposition was assessed using the model of acidification of groundwater in catchments (MAGIC). The model was calibrated at the Panola Mountain Research Watershed, near Atlanta, Georgia, U.S.A. using measured soil properties, wet and dry...
Estimated withdrawals and use of freshwater in Vermont, 1990
M.A. Horn, Laura Medalie
1995, Water-Resources Investigations Report 93-4097
Estimated freshwater withdrawals during 1990 in Vermont totaled about 632 million gallons per day. The largest withdrawals were for thermoelectric- power generation (82 percent), industrial use (7 percent), and public supply (6 percent). Most withdrawals, 587 million gallons per day, were made from surface-water sources as compared to 44.9 million...
Geochemical and hydrologic controls on phosphorus transport in a sewage-contaminated sand and gravel aquifer near Ashumet Pond, Cape Cod, Massachusetts
D. A. Walter, B.A. Rea, K.G. Stollenwerk, Jennifer G. Savoie
1995, Open-File Report 95-381
The disposal of secondarily treated sewage onto rapid infiltration sand beds at the Massachusetts Military Reservation, Cape Cod, Massachusetts, has created a sewage plume in the underlying sand and gravel aquifer; the part of the\x11sewage plume that contains dissolved phosphorus extends about 2,500 feet downgradient of the sewage-disposal beds. A...
Carbon sequestration in an aggrading forest ecosystem in the Southeastern USA
Thomas G. Huntington
1995, Soil Science Society of America Journal (59) 1459-1467
An analysis of C pools at the Panola Mountain Research Watershed (PMRW) near Atlanta, GA, indicates that aggrading forests in the U.S. Southeast are an important regional C sink. The forests in this area were cut in the early 1800s and the land was cultivated until the early 1900s, when...
Hydrologic processes controlling sulfate mobility in a small forested watershed
Thomas G. Huntington, R. P. Hooper, Brent T. Aulenbach
1994, Water Resources Research (30) 283-295
Hydrologic controls on sulfate mobility were investigated in a forested catchment in the Georgia Piedmont using a watershed mass balance approach. Variations in annual sulfate export were governed primarily by differences in runoff rather than by differences in sulfate deposition or in total annual precipitation. However, 2 years with similar...
Simulation of the effects of ground-water withdrawals and recharge on ground-water flow in Cape Cod, Martha's Vineyard, and Nantucket Island basins, Massachusetts
John P. Masterson, Paul M. Barlow
1994, Open-File Report 94-316
The effects of changing patterns of ground-water pumping and aquifer recharge on the surface-water and ground-water hydrologic systems were determined for the Cape Cod, Martha's Vineyard, and Nantucket Island Basins. Three-dimensional, transient, ground-water-flow modelS that simulate both freshwater and saltwater flow were developed for the f1ow cells of Cape Cod...

Having reviewed the results of the Integrated Forest Study (IFS) project, we now try to place the results in a larger perspective by very briefly summarizing acid deposition effects and their potential role in forest health in the several forest types represented in the IFS project. This chapter gives brief...
Aluminum in soil solutions from a subalpine spruce-fir forest at Whiteface Mountain, New York
E. K. Miller, Thomas G. Huntington, A. H. Johnson, A. J. Friedland
1992, Journal of Environmental Quality (21) 345-352
Direct or indirect Al toxicity has been suggested as a principal factor in forest tree declines. We monitored ambient soil solutions in undisturbed and experimentally manipulated soils from a fir [Abies balsamea (L.) Mill.]-spruce forest on Whiteface Mountain, NY, in order to characterize soil solution Al concentrations over a range of...
Redistribution of soil nitrogen, carbon and organic matter by mechanical disturbance during whole-tree harvesting in northern hardwoods
D.F. Ryan, Thomas G. Huntington, Martin C. Wayne
1992, Forest Ecology and Management (49) 87-99
To investigate whether mechanical mixing during harvesting could account for losses observed from forest floor, we measured surface disturbance on a 22 ha watershed that was whole-tree harvested. Surface soil on each 10 cm interval along 81, randomly placed transects was classified immediately after harvesting as mineral or organic, and...
