Changes in water quality of Michigan streams near urban areas, 1973-84
D. J. Holtschlag
1987, Water-Resources Investigations Report 87-4035
Monthly water-quality monitoring of streams was begun by Michigan Department of Natural Resources in 1973 to (1) determine temporal and spatial variability, (2) detect long-term trends, and (3) describe changes in water quality near urban areas. This report provides a statistical analysis and summary of data collected from 1973 through...
Hydrology of the White Tail Butte area, northern Campbell County, Wyoming
M.E. Lowry, J.G. Rankl
1987, Water-Resources Investigations Report 82-4117
Quantity of runoff and peak discharge from one small basin in the White Tail Butte area, determined from a calibrated rainfall-runoff model, is less than the quantity computed using results of a regional study. The difference is caused by the extensive beds of exposed, permeable clinker in the area. Potentiometric...
Effect of grid size on digital simulation of ground-water flow in the southern High Plains of Texas and New Mexico
R. R. Luckey, D.M. Stephens
1987, Water-Resources Investigations Report 87-4085
Three models of the aquifer in the southern High Plains were compared to determine the effect of grid size on simulated water levels. The first model, calibrated prior to this study, had 10-mi grid spacing. The mean difference between the simulated and measured pre-development water levels in this model was...

Movement and fate of ethylene dibromide (EDB) in ground water in Seminole County, Georgia
J. B. McConnell
1987, Water-Resources Investigations Report 87-4030
An investigation to assess the movement and fate of ethylene dibromide (EDB) in the Upper Floridan aquifer (formerly the principal artesian aquifer) was conducted, because a previous investigation conducted in August 1983, had found EDB contamination of the aquifer in about a 4 sq mi area in central Seminole County,...
Flooding of December 29, 1984 through January 2, 1985, in northern New York State, with flood profiles of the Black and Salmon rivers
Richard Lumia, P. M. Burke, W. H. Johnston
1987, Water-Resources Investigations Report 86-4191
Precipitation, snowmelt, and resultant flooding throughout northern New York from December 28 through January 2, 1985, were investigated through a detailed analysis of 56 precipitation stations, 101 stage and/or discharge gaging stations, and 9 miscellaneous measurement sites. Flood damage to property and roads and bridges exceeded $5 million. Lewis and...

Flood hazards along the Toutle and Cowlitz rivers, Washington, from a hypothetical failure of Castle Lake blockage
Antonius Laenen, L.L. Orzol
1987, Water-Resources Investigations Report 87-4055
A recent evaluation of groundwater and material in the blockage impounding Castle Lake shows that the blockage is potentially unstable against failure from piping due to heave and internal erosion when groundwater levels are seasonally high. There is also a remote possibility that a 6.8 or greater magnitude earthquake could...
A computer program for geochemical analysis of acid-rain and other low-ionic-strength, acidic waters
P.A. Johnsson, D. G. Lord
1987, Water-Resources Investigations Report 87-4095-A
ARCHEM, a computer program written in FORTRAN 77, is designed primarily for use in the routine geochemical interpretation of low-ionic-strength, acidic waters. On the basis of chemical analyses of the water, and either laboratory or field determinations of pH, temperature, and dissolved oxygen, the program calculates the equilibrium distribution of...
Three-dimensional model simulation of transient ground-water flow in the Albuquerque-Belen Basin, New Mexico
J. M. Kernodle, Ryan S. Miller, W. B. Scott
1987, Water-Resources Investigations Report 86-4194
A three-dimensional digital model that simulates transient flow in the alluvial aquifer system underlying the Albuquerque-Belen Basin, New Mexico, was constructed as part of a regional aquifer study of the southwest alluvial basins. The model simulates hydraulic heads and changes in hydraulic heads for 1907 to 1979. Hydraulic-conductivity values used...
Hydrogeology and ground-water quality of the northern part of the Town of Oyster Bay, Nassau County, New York, in 1980
Chabot Kilburn, R.K. Krulikas
1987, Water-Resources Investigations Report 85-4051
This report presents geohydrologic and water quality data from the northern part of the Town of Oyster Bay, in the north-shore area of Long Island. The groundwater reservoir underlying the area consists of clay, silt, sand, and gravel layers that form six geohydrologic units; from bottom to top: the Lloyd...
Water resources of Walworth County, South Dakota
Jack Kume, Lewis Howells
1987, Water-Resources Investigations Report 85-4015
The water resources of Walworth County, South Dakota are for the most part undeveloped. In 1978, only about 10,000 acre-feet of water was used for irrigation, stock, domestic, and public supplies; most of this water came form Lake Oahe on the Missouri River, and was used for irrigation. The lake...
HST3D; a computer code for simulation of heat and solute transport in three-dimensional ground-water flow systems
K.L. Kipp
1987, Water-Resources Investigations Report 86-4095
The Heat- and Soil-Transport Program (HST3D) simulates groundwater flow and associated heat and solute transport in three dimensions. The three governing equations are coupled through the interstitial pore velocity, the dependence of the fluid density on pressure, temperature, the solute-mass fraction , and the dependence of the fluid viscosity on...
Effects of agricultural best-management practices on total phosphorus yields in the Johnson Brook and Lovejoy Pond watersheds, Kennebec County, Maine, 1980-84
Thomas J. Maloney, John W. Sowles
1987, Water-Resources Investigations Report 87-4118
Analysis of daily phosphorus yield and streamflow data collected before and after implementation of agricultural best management practices in the Johnson Brook watershed in south-central Maine indicated statistically significant reductions in phosphorus loading in all flow categories. Reduction of median loadings for five flow categories ranged from 26% to 90%....
Hydrology and water-quality at the Weldon Spring radioactive waste-disposal sites, St. Charles County, Missouri
M. J. Kleeschulte, L. F. Emmett
1987, Water-Resources Investigations Report 87-4169
Water samples from five monitoring wells adjacent to raffinate pits storing low-level radioactive waste contained concentrations of nitrate as nitrogen ranging from 53 to 990 milligrams per liter. Most samples also had maximum concentrations of calcium (900 milligrams per liter), sodium (340 milligrams per liter), sulfate (320 milligrams per liter),...
