J. Srodon, D.J. Morgan, E.V. Eslinger, D. D. Eberl, M.R. Karlinger
1986, Clays and Clay Minerals (34) 368-378
Chemical data from three different series of diagenetic illite/smectites (I/S), analyzed statistically by two regresion techniques, indicate that the content of fixed-K per illite layer is not constant, but ranges from ∼0.55 per O10(OH)2 for illite layers in randomly interstratified I/S (R=0; > 50% smectite layers) to ∼1.0 per O10(OH)2 for illite...
Digital image measurement of the area and anatomical structure of tree rings
Thomas M. Yanosky, Charles J. Robinove
1986, Canadian Journal of Botany (64) 2896-2902
A microcomputer coupled to a video digitizer was used to develop methods for measuring areas of tree rings and for delineating and measuring microscopic anatomical features. Digitally imaged areas of individual rings of a loblolly pine cross section were within 2.6% of areas measured with a planimeter and were more...
Transport of chloride ion in a water-unsaturated soil exhibiting anion exclusion
Ronald V. James, Jacob Rubin
1986, Soil Science Society of America Journal (50) 1142-1149
Miscible displacement techniques were used to create Cl- concentration profiles in unsaturated laboratory columns of Delhi sand (Typic Xeropsamments), each having a nearly uniform water content. The three steady flow rates used resulted in three different, average water contents. Chloride concentrations near the top of the column were smaller and...
Aqueous geochemistry and diagenesis in the eastern Snake River Plain aquifer system, Idaho
Warren W. Wood, Walton H. Low
1986, Bulletin (97) 1456-1466
Water budget and isotopic analyses of water in the eastern Snake River Plain aquifer system confirm that most, if not all, of the water is local meteoric in origin. Solute mass-balance arguments suggest that ∼5 × 109 moles of calcite and 2.6 × 109 moles of silica are precipitated annually...
Influence of irrigation on salinity and nitrate in a stream-aquifer system
Leonard F. Konikow, M.A. Person
1986, Conference Paper, Conjunctive water use: understanding and managing surfacewater-groundwater interactions
Changes in salinity and nitrate concentration in groundwater and surface water in the semiarid Arkansas River valley of southeastern Colorado, USA were related primarily to irrigation practices. Water is applied to fields by flood irrigation through ditches and furrows. Irrigation water is derived in nearly equal amounts from surface water...
Application of the Flory-Huggins theory to the solubility of solids in glyceryl trioleate
Cary T. Chiou, Milton Manes
1986, Journal of the Chemical Society, Faraday Transactions I (82) 243-246
The conventional thermodynamic deviation for ideal solid–liquid solubilities is modified by substituting the Flory–Huggins model for Raoult's law. A comparison of published data for eleven solides in glyceryl trioleate with the predictions of the conventional and modified equations shows that the significantly higher athermal solubilities from the modified...

A 5-year, data-collection and modeling study was conducted on Pheasant Branch basin in and near Middleton, Wisconsin. The objectives of the study were to: (1) describe the streamflow characteristics, sediment transport, and stream-channel morphology in the Pheasant Branch basin; and (2) relate the above factors to changes caused by urbanization...
Louisiana hydrologic atlas map no. 2: Areal extent of freshwater in major aquifers of Louisiana
Charles W. Smoot
1986, Water-Resources Investigations Report 86-4150
The areal availability of freshwater (cl content < 250 mg/L) in 14 major aquifers in Louisiana was investigated. The depth of occurrence of fresh groundwater in Louisiana is variable. The aquifers were mapped to show their areal extent from the outcrop or subcrop to the downdip limit of freshwater. Water...
Louisiana hydrologic atlas map no. 1: Mean annual runoff in Louisiana
Harry C. McWreath III, Alfred S. Lowe
1986, Water-Resources Investigations Report 86-4149
The map shows the mean annual runoff from drainage basins in Louisiana exclusive of those in the coastal zone and the alluvial valleys of the Mississippi, Ouachita, and Red Rivers. The mean annual runoff for the State of Louisiana varies from 0.7 (cu ft/s)/sq mi in the Sabine and Red...

C. R. Causaras
1986, Water-Resources Investigations Report 86-4126
The geologic framework of the surficial aquifer system in Dade County, Florida, was investigated as part of a longterm study by the USGS in cooperation with the South Florida Water Management District, to describe the geology, hydrologic characteristics, and groundwater quality of the surficial aquifer system. Thirty-three test wells were...
Hydrogeologic framework of the Floridan aquifer system in Florida and in parts of Georgia, Alabama, and South Carolina
James A. Miller
1986, Professional Paper 1403-B
The Floridan aquifer system of the Southeastern United States is comprised of a thick sequence of carbonate rocks that are mostly of Paleocene to early Miocene age and that are hydraulically connected in varying degrees. The aquifer system consists of a single vertically continuous permeable unit updip and of two...
Movement and fate of creosote waste in ground water, Pensacola, Florida; U.S. Geological Survey toxic waste-ground-water contamination program

H.C. Mattraw Jr., editor(s)
1986, Water Supply Paper 2285
Ground- and surface-water contamination by pesticides used in the wood-preserving industry is widespread in the United States. Pine poles were treated with wood preservatives from 1902 to 1981 at a creosote works near Pensacola, Florida. Diesel fuel, creosote, and pentachlorophenol were discharged to two unlined impoundments that had a direct...
Use of detrended correspondence analysis in evaluating factors controlling species composition of periphyton
Harry V. Leland, James L. Carter
Isom Billy G., editor(s)
1986, Book chapter, Rationale for sampling and interpretation of biological data in the assessment of freshwater ecosystems
Detrended correspondence analysis (DCA) was evaluated for its usefulness in elucidating relationships among samples and among species of periphyton in an oligotrophic stream, and for its effectiveness in displaying major gradients where an experimental gradient (copper) affecting species composition was imposed. It was highly sensitive to differences among samples and...

1985, Journal of Hydrology (76) 85-106
The Rocky Mountain Arsenal near Denver, Colorado, U.S.A., is used as a realistic setting for a hypothetical test of a procedure that plans the hydraulic stabilization and removal of a groundwater contaminant plume. A two-stage planning procedure successfully selects the best wells and their optimal pumping/recharge schedules to contain the...

M. Kemblowski
1985, Journal of Hydrology (78) 35-47
The boundary-element method is used to solve the set of partial differential equations describing the flow of salt water and fresh water separated by a sharp interface in the vertical plane. In order to improve the accuracy and stability of the numerical solution, a new implicit scheme was developed for...

T. E. Reilly, A.S. Goodman
1985, Journal of Hydrology (80) 125-160
Although much progress has been made toward the mathematical description of saltwater-freshwater relationships in groundwater systems since the late 19th century, the advective and dispersive mechanisms involved are still incompletely understood. This article documents the major historical advances in this subject and summarizes the major direction of current studies. From...

M. Sophocleous, C. A. Perry
1985, Journal of Hydrology (81) 297-332
The amounts and time distribution of groundwater recharge from precipitation over an approximately 19-month period were investigated at two instrumented sites in south-central Kansas.

Evaluating the hydraulic effects of changes in aquifer elevation using curvilinear coordinates
E. Weiss
1985, Journal of Hydrology (81) 253-275
The groundwater flow equation is written in curvilinear coordinates whose coordinate surfaces coincide with the top and bottom surfaces of folded layers of aquifers. The coordinates are general enough for these surfaces to coincide for almost all groundwater systems. The terms of the finite-difference approximation for the flow equation can...
