Hydro-climatic data network (HCDN); a U.S. Geological Survey streamflow data set for the United States for the study of climate variations, 1874-1988
J. R. Slack, Jurate Maciunas Landwehr
1992, Open-File Report 92-129
Records of streamflow can provide an account of climatic variation over a hydrologic basin. The ability to do so is conditioned on the absence of confounding factors that diminish the climate signal. A national data set of streamflow records that are relatively free of confounding anthropogenic influences has been developed...

Herbicide and nitrate variation in alluvium underlying a cornfield at a site in Iowa County, Iowa
S. J. Kalkhoff, M.G. Detroy, K. Cherryholmes, R.L. Kuzniar
1992, Journal of the American Water Resources Association (28) 1001-1011
A hydrologic investigation to determine vertical and seasonal variation of atrazine, alachlor, cyanazine, and nitrate at one location and to relate the variation to ground-water movement in the Iowa River alluvium was conducted in Iowa County, Iowa, from March 1986 to December 1987. Water samples were collected at discrete intervals...
Deposition of aerially applied BT in an oak forest and its prediction with the FSCBG model
Dean E. Anderson, David R. Miller, Yansen Wang, William G. Yendol, Karl Mierzejewski, Michael L. McManus
1992, Journal of Applied Meteorology (31) 1457-1466
Data are provided from 17 single-swath aerial spray trials that were conducted over a fully leafed, 16-m tall, mixed oak forest. The distribution of cross-swath spray deposits was sampled at the top of the canopy and below the canopy. Micrometeorological conditions were measured above and within the canopy during the...

A geochemical transport model for redox-controlled movement of mineral fronts in groundwater flow systems: A case of nitrate removal by oxidation of pyrite
Peter Engesgaard, Kenneth L. Kipp
1992, Water Resources Research (28) 2829-2843
A one-dimensional prototype geochemical transport model was developed in order to handle simultaneous precipitation-dissolution and oxidation-reduction reactions governed by chemical equilibria. Total aqueous component concentrations are the primary dependent variables, and a sequential iterative approach is used for the calculation. The model was verified by analytical and numerical comparisons and...
Modeling biotic uptake by periphyton and transient hyporrheic storage of nitrate in a natural stream
Brian K.A. Kim, Alan P. Jackman, Frank J. Triska
1992, Water Resources Research (28) 2743-2752
To a convection-dispersion hydrologic transport model we coupled a transient storage submodel (Bencala, 1984) and a biotic uptake submodel based on Michaelis-Menten kinetics (Kim et al., 1990). Our purpose was threefold: (1) to simulate nitrate retention in response to change in load in a third-order stream, (2) to differentiate biotic...
Use of chlorofluorocarbons (CCl3F and CCl2F2) as hydrologic tracers and age‐dating tools: The alluvium and terrace system of central Oklahoma
Eurybiades Busenberg, Niel Plummer
1992, Water Resources Research (28) 2257-2283
The use of Chlorofluorocarbons (CFCs) as an age‐dating tool and tracer in shallow groundwaters has been investigated. New methodology for field sampling and preserving groundwaters containing parts per trillion concentrations of the CFCs, F‐1l and F‐12, is presented. Samples are analyzed by purge‐and‐trap gas chromatography with an electron...
Inductively coupled plasma-mass spectrometry as an element-specific detector for field-flow fractionation particle separation
Howard E. Taylor, John R. Garbarino, Deirdre M. Murphy, Ronald Beckett
1992, Analytical Chemistry (64) 2036-2041
An inductively coupled plasma-mass spectrometer was used for the quantitative measurement of trace elements In specific,submicrometer size-fraction particulates, separated by sedimentation field-flow fractionation. Fractions were collected from the eluent of the field-flow fractionation centrifuge and nebulized, with a Babington-type pneumatic nebulizer, into an argon inductively coupled plasma-mass spectrometer. Measured Ion...
Relation of nickel concentrations in tree rings to groundwater contamination
Thomas M. Yanosky, Don A. Vroblesky
1992, Water Resources Research (28) 2077-2083
Increment cores were collected from trees growing at two sites where groundwater is contaminated by nickel. Proton-induced X ray emission spectroscopy was used to determine the nickel concentrations in selected individual rings and in parts of individual rings. Ring nickel concentrations were interpreted on the basis of recent concentrations of...
Large-scale natural gradient tracer test in sand and gravel, Cape Cod, Massachusetts: 3. Hydraulic conductivity variability and calculated macrodispersivities
Kathryn M. Hess, Steven H. Wolf, Michael A. Celia
1992, Water Resources Research (28) 2011-2027
Hydraulic conductivity (K) variability in a sand and gravel aquifer on Cape Cod, Massachusetts, was measured and subsequently used in stochastic transport theories to estimate macrodispersivities. Nearly 1500 K measurements were obtained by borehole flowmeter tests and permeameter analyses of cores. The geometric mean for the flowmeter tests (0.11 cm/s)...
Precipitation estimation in mountainous terrain using multivariate geostatistics. Part I: structural analysis
Joseph A. Hevesi, Jonathan D. Istok, Alan L. Flint
1992, Journal of Applied Meteorology (31) 661-676
Values of average annual precipitation (AAP) are desired for hydrologic studies within a watershed containing Yucca Mountain, Nevada, a potential site for a high-level nuclear-waste repository. Reliable values of AAP are not yet available for most areas within this watershed because of a sparsity of precipitation measurements and the need...
Precipitation estimation in mountainous terrain using multivariate geostatistics. Part II: isohyetal maps
Joseph A. Hevesi, Alan L. Flint, Jonathan D. Istok
1992, Journal of Applied Meteorology (31) 677-688
Values of average annual precipitation (AAP) may be important for hydrologic characterization of a potential high-level nuclear-waste repository site at Yucca Mountain, Nevada. Reliable measurements of AAP are sparse in the vicinity of Yucca Mountain, and estimates of AAP were needed for an isohyetal mapping over a 2600-square-mile watershed containing...

Solute transport with multiple equilibrium-controlled or kinetically controlled chemical reactions
John C. Friedly, Jacob Rubin
1992, Water Resources Research (28) 1935-1953
A new approach is applied to the problem of modeling solute transport accompanied by many chemical reactions. The approach, based on concepts of the concentration space and its stoichiometric subspaces, uses elements of the subspaces as primary dependent variables. It is shown that the resulting model equations are compact in...

Reply to Dr. Stoesselfs comment on “Reaction paths and equilibrium end-points in solid-solution aqueous-solution systems”
Pierre D. Glynn, Eric J. Reardon, Niel Plummer, Eurybiades Busenberg
1992, Geochimica et Cosmochimica Acta (56) 2559-2572
In reply to the Critical Comment of R. K. Stoessell (this issue), limiting activity coefficients of bromide in halite (γNaBr) have been calculated by least-squares fitting of Simons et al.'s (1952) bromide distribution coefficient data for the Na(Cl,Br)-NaOH-H2O system at 35°C. Regular and subregular solidsolution model fits give γNaBr...

James S. Kuwabara
1992, Freshwater Science (11) 218-222
Diel relationships between physical and chemical parameters and biomass were examined along a 57-km reach of Whitewood Creek, South Dakota, between 29 August and 2 September 1988. A time lag of ∼3-6 h for fluctuations in soluble reactive phosphorus (SRP) concentrations (ranging from 0.1 to 0.5 μM at the downstream...
Solute transport with multisegment, equilibrium-controlled, classical reactions: Problem solvability and feed forward method's applicability for complex segments of at most binary participants
Jacob Rubin
1992, Water Resources Research (28) 1681-1702
The feed forward (FF) method derives efficient operational equations for simulating transport of reacting solutes. It has been shown to be applicable in the presence of networks with any number of homogeneous and/or heterogeneous, classical reaction segments that consist of three, at most binary participants. Using a sequential (network type...

Larry L. Jackson, A.L. Foote, Laurie S. Balistrieri
1992, Journal of Coastal Research 306-323
Hydrological conditions are reported for the hurricane-induced storm surge at marsh sites in Terrebonne and Barataria Basins. There was a 6 hour or greater delay in the arrival of the storm surge at interior marsh sites compared to coastal locations. A water surge of about 1.5 m with a salinity...
