P. K. Showalter, J. P. Akers, L.A. Swain
1984, Water-Resources Investigations Report 83-4049
A regional ground-water quality monitoring network for the entire Salinas River drainage basin was designed to meet the needs of the California State Water Resources Control Board. The project included phase 1--identifying monitoring networks that exist in the region; phase 2--collecting information about the wells in each network; and phase...
The principle of superposition and its application in ground-water hydraulics
T. E. Reilly, O.L. Franke, G.D. Bennett
1984, Open-File Report 84-459
The principle of superposition, a powerful methematical technique for analyzing certain types of complex problems in many areas of science and technology, has important application in ground-water hydraulics and modeling of ground-water systems. The principle of superposition states that solutions to individual problems can be added together to obtain solutions...
Ground-water resources of Limestone County, Texas
P.L. Rettman
1984, Open-File Report 84-713
Limestone County, located in east-central Texas, has small to plentiful ground-water supplies available, depending upon the location within the county. The Wilcox Group in the eastern part of the county has adequate supplies to meet the expected water demands in the foreseeable future. The thicker zones of the Wilcox Group...
Conceptual hydrologic model of flow in the unsaturated zone, Yucca Mountain, Nevada
P.M. Montazer, W.E. Wilson
1984, Water-Resources Investigations Report 84-4345
The unsaturated volcanic tuffs beneath Yucca Mountain, Nevada, are being evaluated as a host rock for a potential repository for high-level radioactive waste. A conceptual hydrologic model is proposed to describe the flow of fluids through these rocks. Thickness of the unsaturated zone is about 500 to 750 meters and...
Ground water in the Fresno area, California; preliminary report
H. T. Mitten
1984, Water-Resources Investigations Report 83-4246
The U.S. Geological Survey, in cooperation with Fresno County, is developing a computer model of the unconfined aquifer system in the Fresno area. In the area, consolidated rocks are overlain by unconsolidated deposits. The unconsolidated deposits are divided into a lower fine-grained unit and an overlying coarse-grained unit. The system...
Ground water hydrology of the Elizabethtown area, Kentucky
D. S. Mull, M. A. Lyverse
1984, Water-Resources Investigations Report 84-4057
The principal aquifer in a 52 square mile karst area in north central Kentucky is the St. Louis Limestone of Mississippian age. Unconsolidated residuum and surficial deposits of slumped material may store water and recharge the underlying limestone aquifer. Precipitation averages 49 inches annually; 6 inches recharges ground-water reservoirs. The...

H. A. Martinson
1984, Water-Resources Investigations Report 83-4128
Bank erosion and changes in channel width, length, and pattern were determined for the Powder River between Moorhead and Broadus, Montana using maps of the bankfull channel made from aerial photographs taken during 1939, 1954, 1967, 1973, and 1978. Contemporaneous daily mean and peak discharge records from Moorhead provide the...
Cost effectiveness of the U.S. Geological Survey's stream-gaging program in Illinois
D. M. Mades, K. A. Oberg
1984, Water-Resources Investigations Report 84-4123
Data uses and funding sources were identified for 138 continuous-record discharge-gaging stations currently (1983) operated as part of the stream-gaging program in Illinois. Streamflow data from five of those stations are used only for regional hydrology studies. Most streamflow data are used for defining regional hydrology, defining rainfall-runoff relations, flood...

Water-data program of the US Geological Survey in Kansas, fiscal year 1983
R.K. Livingston, K.D. Medina
1984, Water-Resources Investigations Report 84-4306
The U.S. Geological Survey is the principal Federal agency responsible for the collection of hydrologic data needed for the planning, development, use, and management of the water resources in Kansas. Hydrologic-data collection by the U.S. Geological Survey in Kansas began in 1895. The fiscal-year 1983 water-data program, operated in cooperation...
Summary of water-resources activities of the U.S. Geological Survey in Colorado: fiscal year 1984
Water Resources Division, U.S. Geological Survey
1984, Report
Water-resources investigations of the U.S. Geological Survey in Colorado consist of collecting water-resources data and conducting interpretive hydrologic investigations. The water-resources data and the results of the investigations are published or released by either the U.S. Geological Survey or by cooperating agencies. This report describes the water- resources investigations in...
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...

Areal lithologic changes in bedrock aquifers in southeastern Minnesota as determined from natural-gamma borehole logs methods
D. G. Woodward
1984, Conference Paper
Sedimentary rocks of Paleozoic age in the Hollandale embayment in southeastern Minnesota are as much as 2,000 feet thick and, with the underlying Hinckley sandstone of Proterozoic age, comprise the following five layered aquifers (beginning with the oldest): the Mount Simon-Hinckley, Ironton-Galesville, Prairie du Chien-Jordan, St. Peter and Upper Carbonate....

1984, Circular 921
The eruptions of Mount St. Helens volcano, Wash., constituted one of the major national and international news stories of 1980 and involved the U.S. Geological Survey in more news coverage than any other event in its history. Much of the information about the volcano came from monitoring and research by...

Compilation of hydrologic data for the Edwards Aquifer, San Antonio area, Texas, 1981, with 1934-81 summary
R.D. Reeves, R.W. Maclay, G. B. Ozuna
1984, Edwards Underground Water District Bulletin 41
The average annual ground-water recharge to the Edwards aquifer in the San Antonio area, Texas, from 1934 through 1981, was 612,400 acre-feet. The recharge in 1981 was 1,448,400 acre-feet, which is the third highest annual recharge since 1934. A maximum annual recharge of 1,711,200 acre-feet occurred in 1958, and a...
Volatilization of chlorinated hydrocarbons from water
R. E. Rathbun, D. Y. Tai
1984, Book chapter, Gas transfer at water surfaces
Coefficients for the volatilization from water of 1,1,1-trichloroethane and 1,2-dichloroethane were measured in a stirred tank. Experiments at constant mixing conditions over a wide range of concentrations showed that the volatilization coefficient was independent of concentration, confirming the assumption that volatilization is a first order process. Simultaneous measurements of the...
Volatilization of ketones
R. E. Rathbun, D. Y. Tai
1984, Chemosphere (13) 1009-1023
Volatilization fluxes of seven ketones were measured over a range of temperatures. Gas-film coefficients were calculated from these volatilization fluxes and related to the gas-film coefficient for the evaporation of water. These relations, when combined with an equation for estimating the gas-film coefficient for evaporation of water from a canal,...
Denitrification in San Francisco Bay intertidal sediments
Ronald S. Oremland, Cindy Umberger, Charles W. Culbertson, Richard L. Smith
1984, Applied and Environmental Microbiology (47) 1106-1112
The acetylene block technique was employed to study denitrification in intertidal estuarine sediments. Addition of nitrate to sediment slurries stimulated denitrification. During the dry season, sediment-slurry denitrification rates displayed Michaelis-Menten kinetics, and ambient NO3− + NO2− concentrations (≤26 μM) were below the apparent Km (50 μM) for nitrate. During the rainy season, when ambient...
