Estimation of the recharge area contributing water to a pumped well in a glacial-drift, river-valley aquifer
D. J. Morrissey
1987, Open-File Report 86-543
The highly permeable, unconfined, glacial drift aquifers that occupy most New England river valleys constitute the principal source of drinking water for many communities that obtain part or all of their public water supply from groundwater. Analytical , two-dimensional numerical and three-dimensional numerical models were used to delineate contributing areas...

1987, Limnology and Oceanography (32) 781-793
Bacterial activities and abundance were measured seasonally in the water column of meromictic Big Soda Lake which is divided into three chemically distinct zones: aerobic mixolimnion, anaerobic mixolimnion, and anaerobic monimolimnion. Bacterial abundance ranged between 5 and 52 x 106 cells ml−1, with highest biomass at the interfaces between these zones:...
Methods and applications in surface depression analysis
Susan K. Jenson, Charles M. Trautwein
1987, Conference Paper, Auto-Carto VIII: Proceedings of the international symposium on computer-assisted cartography
Gridded surface data sets are often incorporated into digital data bases, but extracting information from the data sets requires specialized raster processing techniques different from those historically used on remotely sensed and thematic data. Frequently, the information desired of a gridded surface is directly related to the topologic peaks and...
Geomorphic and hydrologic dynamics of zero-order basins
Richard M. Iverson
1987, Eos, Transactions, American Geophysical Union (68) 1808-1808
The 1987 International Symposium on Erosion and Sedimentation in the Pacific Rim, held August 3–7, 1987, in Corvallis, Oreg., included a special session on the geomorphic and hydrologic dynamics of zero-order drainage basins. “Zero-order basin” is one of several terms used to describe unchanneled swales or hollows...

Laboratory investigation of longitudinal dispersion in anisotropic porous media
Stephen E. Silliman, Leonard F. Konikow, C.I. Voss
1987, Water Resources Research (23) 2145-2151
In this study, laboratory experiments were used to investigate mechanisms that may cause anisotropy in the dispersion coefficient and to investigate the relation between anisotropy in hydraulic conductivity and anisotropy in longitudinal dispersion. Measurements of sodium chloride concentration (used as a tracer) were made at 105 in situ sampling locations...
Selective transport of hydrocarbons in the unsaturated zone due to aqueous and vapor phase partitioning
Arthur L. Baehr
1987, Water Resources Research (23) 1926-1938
Long-term groundwater contamination can result from vapors and solutes emanating from organic liquids spilled in the unsaturated zone. The mathematical modeling analysis presented in this paper demonstrates for gasoline-range hydrocarbons, and other volatile organics commonly spilled, that diffusive transport in the unsaturated zone is a significant transport mechanism which can...

Movement and fate of crude-oil in contaminants in the subsurface environment at Bemidji, Minnesota: Chapter C in U.S. Geological Survey program on toxic waste--ground-water contamination: Proceedings of the Third technical meeting, Pensacola, Florida, March 23-27, 1987
Marc F. Hult
1987, Open-File Report 87-109-C
On August 20, 1979, a pipeline break in a remote area near Bemidji, Minn. (fig. C-l), resulted in the release of 1.5x105 L (liters) of crude oil. Although about 1.1x105 L were removed from the site as part of the cleanup, some crude oil infiltrated the ground and percolated to the...
