Copper and silver accumulation in transplanted and resident clams (Macoma balthica) in South San Francisco Bay
D.J. Cain, Samuel N. Luoma
1985, Marine Environmental Research (15) 115-135
Accumulation of Cu and Ag by soft tissues of the deposit-feeding clam Macoma balthica was less than half in clams transplanted to a contaminated area than in clams native to that area. During a period of tissue growth, the transplants retained 50% and 90%, respectively, of the net Cu and...
Partitioning studies of coal-tar constituents in a two-phase contaminated ground-water system
Colleen E. Rostad, W. E. Pereira, M. F. Hult
1985, Chemosphere (14) 1023-1036
Organic compounds derived from coal-tar wastes in a contaminated aquifer in St. Louis Park, Minnesota, were identified, and their partition coefficients between the tar phase and aqueous phase were determined and compared with the corresponding n-octanol/water partition coefficients. Coal tar contains numerous polycyclic aromatic compounds, many of which are suspected...
Ground-water hydrology and projected effects of ground-water withdrawals in the Sevier Desert, Utah
Walter F. Holmes
1984, Technical Publication 79
The principal ground-water reservoir in the Sevier Desert is the unconsolidated basin fill. The fill has been divided generally into aquifers and confining beds, although there are no clearcut boundaries between these units--the primary aquifers are the shallow and deep artesian aquifers. Recharge to the ground-water reservoir is by infiltration...

Evaluation of the efficiency of streamflow data collection strategies for alluvial rivers
P.K. Kitanidis, O. G. Lara, R.W. Lane
1984, Journal of Hydrology (72) 85-103
Streamflow discharge is usually determined indirectly from measurements of the river stage at gaging stations and through the use of stage-discharge relationships (rating curves). However, in alluvial streams, stage-discharge relationships change continually and, sometimes, quite markedly. Such changes may be caused by major floods, seasonal variations, or long-term secular trends...
Use of a digital model to evaluate hydrogeologic controls on groundwater flow in a fractured rock aquifer at Niagara Falls, New York, U.S.A.

1984, Journal of Hydrology (75) 167-194
The Hyde Park landfill is a 15-acre (6.1 ha) chemical waste disposal site located north of Niagara Falls, New York. Underlying the site in descending order are: (1) low-permeability glacial till and lacustrine deposits; (2) a moderately permeable fractured rock aquifer - the Lockport Dolomite; and (3) a low-permeability unit...
Transport and concentration controls for chloride, strontium, potassium and lead in Uvas Creek, a small cobble-bed stream in Santa Clara County, California, U.S.A.: 1. Conceptual model
V. C. Kennedy, A. P. Jackman, S.M. Zand, G. W. Zellweger, R.J. Avanzino
1984, Journal of Hydrology (75) 67-110
Stream sediments adsorb certain solutes from streams, thereby significantly changing the solute composition; but little is known about the details and rates of these adsorptive processes. To investigate such processes, a 24-hr. injection of a solution containing chloride, strontium, potassium, sodium and lead was made at the head of a...
Transport and concentration controls for chloride, strontium, potassium and lead in Uvas Creek, a small cobble-bed stream in Santa Clara County, California, U.S.A.: 2. Mathematical modeling
A. P. Jackman, R. A. Walters, V. C. Kennedy
1984, Journal of Hydrology (75) 111-141
Three models describing solute transport of conservative ion species and another describing transport of species which adsorb linearly and reversibly on bed sediments are developed and tested. The conservative models are based on three different conceptual models of the transient storage of solute in the bed. One model assumes the...
Groundwater-flow parameter estimation and quality modeling of the Equus Beds aquifer in Kansas, U.S.A.
M.A. Sophocleous
1984, Journal of Hydrology (69) 197-222
The salinity problems created in the Burrton area as a result of poor oil-field brine disposal practices of the past continue to be a major concern to the area depending on the Equus Beds aquifer for water, including the City of Wichita, Kansas. In this paper, an attempt is made...
Experimental studies in natural groundwater recharge dynamics: Assessment of recent advances in instrumentation
M. Sophocleous, C. A. Perry
1984, Journal of Hydrology (70) 369-382
To quantify and model the natural groundwater-recharge process, two sites in south-central Kansas, U.S.A., were instrumented with various modern sensors and data microloggers. The atmospheric-boundary layer and the unsaturated and saturated soil zones were monitored as a unified regime. Data from the various sensors were collected using microloggers in combination...
