K. J. Breen, D.H. Dumouchelle
1991, Water-Resources Investigations Report 91-4024
The hydrology and quality of ground water were evaluated for the surficial sand and carbonate aquifers in northwestern Ohio. A locally important surficial sand aquifer in western Lucas County was evaluated on the basis of data from 10 wells completed in undeveloped and developed areas. The carbonate aquifer in Silurian...
Bibliography of Regional Aquifer-System Analysis Program of the US Geological Survey, 1978-91
Ren Jen Sun, John B. Weeks
1991, Water-Resources Investigations Report 91-4122
The Regional Aquifer-System Analysis (RASA) Program of the U.S. Geological Survey was initiated in 1978. The purpose of this program is to define the regional geohydrology and establish a framework of background information on geology, hydrology, and geochemistry of the Nation's important aquifer systems. This information is critically needed to...

D. M. Sumner, W.M. Schuh, R.L. Cline
1991, Water-Resources Investigations Report 91-4127
Ponded depth in an artificial-recharge basin was used as a management option to conduct turbid water from the James River to the Oakes aquifer. Infiltration-rate response to changes in ponded depth was evaluated for a 15xl5-meter artificial-recharge test basin constructed in a medium-sandy soil in the irrigation area near Oakes,...

Alan W. Decho, Samuel N. Luoma
1991, Marine Ecology Progress Series (78) 303-314
Time courses for ingestion, retention and release via feces of microbial food was investigated using 2 bivalves with different feeding strategies, Potamocorbula amurensis and Macoma balthica. The results showed 2 pathways for the uptake of food material in these clams. The first is represented by an initial label pulse in the feces. The...
A modeling assessment of the thermal regime for an urban sport fishery
John M. Bartholow
1991, Environmental Management (15) 833-845
Water temperature is almost certainly a limiting factor in the maintenance of a self-sustaining rainbow trout (Oncorhynchus mykiss, formerly Salmo gairdneri) and brown trout (Salmo trutta) fishery in the lower reaches of the Cache la Poudre River near Fort Collins, Colorado, USA. Irrigation diversions dewater portions of the river, but...
Global warming and prairie wetlands: potential consequences for waterfowl habitat
Karen A. Poiani, W. Carter Johnson
1991, BioScience (41) 611-618
The accumulation of greenhouse gasses in the atmosphere is expected to warm the earth's climate at an unprecedented rate (Ramanathan 1988, Schneider 1989). If the climate models are correct, within 100 years the earth will not only be warmer than it has been during the past million years, but...
Geochemistry of dissolved inorganic carbon in a Coastal Plain aquifer. 2. Modeling carbon sources, sinks, and δ13C evolution
Peter B. McMahon, Francis H. Chapelle
1991, Journal of Hydrology (127) 109-135
Stable isotope data for dissolved inorganic carbon (DIC), carbonate shell material and cements, and microbial CO2 were combined with organic and inorganic chemical data from aquifer and confining-bed pore waters to construct geochemical reaction models along a flowpath in the Black Creek aquifer of South Carolina. Carbon-isotope fractionation between DIC...

C.C. Truman, L.E. Asmussen, H.D. Allison
1991, Journal of Soil and Water Conservation (46) 370-373
Ground-penetrating radar was evaluated as a tool for mapping reservoir and lake bottoms and providing stage-storage information. An impulse radar was used on a 1.4-ha (3.5-acre) reservoir with 31 transects located 6.1 m (20 feet) apart. Depth of water and lateral extent of the lake bottom were accurately measured by...
Hydrologic pathways and chemical composition of runoff during snowmelt in Loch Vale Watershed, Rocky Mountain National Park, Colorado, USA
A. Scott Denning, Jill Baron, M. Alisa Mast, Mary Arthur
1991, Water, Air, & Soil Pollution (59) 107-123
Intensive sampling of a stream draining an alpine-subalpine basin revealed that depressions in pH and acid neutralizing capacity (ANC) of surface water at the beginning of the spring snowmelt in 1987 and 1988 were not accompanied by increases in strong acid anions, and that surface waters did not become acidic...

Evaluation of hydraulic conductivities calculated from multi-port permeameter measurements

1991, Groundwater (29) 516-525
A multiport permeameter was developed for use in estimating hydraulic conductivity over intact sections of aquifer core using the core liner as the permeameter body. Six cores obtained from one borehole through the upper 9 m of a stratified glacial-outwash aquifer were used to evaluate the reliability of the permeameter....
Quartz dissolution in organic-rich aqueous systems
Philip C. Bennett
1991, Geochimica et Cosmochimica Acta (55) 1781-1797
Organic electrolytes are a common component of natural waters and are known to be important in many rock-water interactions. The influence of organic electrolytes on silica mobility, quartz solubility, and quartz dissolution kinetics, however, is less well understood. While there is mounting evidence supporting the presence of an aqueous organic-silica...

Centrifugal techniques for measuring saturated hydraulic conductivity
John R. Nimmo, Karen A. Mello
1991, Water Resources Research (27) 1263-1269
Centrifugal force is an alternative to large pressure gradients for the measurement of low values of saturated hydraulic conductivity (Ksat). With a head of water above a porous medium in a centrifuge bucket, both constant-head and falling-head measurements are practical at forces up to at least 1800 times normal gravity....
Extent of reaction in open systems with multiple heterogeneous reactions
John C. Friedly
1991, American Institute of Chemical Engineers (37) 687-693
The familiar batch concept of extent of reaction is reexamined for systems of reactions occurring in open systems. Because species concentrations change as a result of transport processes as well as reactions in open systems, the extent of reaction has been less useful in practice in...
