Margaret G. Hopper, B. Glen Reagor
1980, Open-File Report 80-1242
The magnitude 5.2 (mb) northern Kentucky earthquake of July 27, 1980, at 18:52:21.8 UTC, located at 38.17N, 83.91W with a depth of 8 km (as determined by the National Earthquake Information Service), was particularly notable for the widespread damage it did, especially to older chimneys. Investigators from several different organizations...
Ground-water hydrology of James City County, Virginia
John F. Harsh
1980, Open-File Report 80-961
Urbanization and increase in water demand prompted a 2-year study of groundwater availability and quality in the county of James City. The coastal-plain sediments, parts of which underlie the county, are the largest source of groundwater in Virginia. Four aquifers form the complex aquifer system. Hydraulic characteristics vary from aquifer...

Effects of selected sources of contamination on ground-water quality at seven sites in Connecticut
Elinor H. Handman, James W. Bingham
1980, Open-File Report 79-1596
The introduction of contaminants has altered the quality of ground water at several places in Connecticut. This investigation of the hydrogeologic environment and the quality of water in stratified-drift aquifers underlying seven probable contaminant sources in Connecticut shows some effects at each site. Water from test wells downgradient from septage-disposal...

Copper River hydraulic study at Million Dollar Bridge, Alaska
Stanley H. Jones, William F. Barber
1980, Open-File Report 80-223
The Copper River hydraulic conditions in the vicinity of the Million-Dollar Bridge, Alaska, at the outlet to Miles Lake are described. The water discharge, lake and river bed profiles, bathymetry, velocity, and direction of flow are presented. (Kosco-USGS)...
Preliminary appraisal of ephemeral-streamflow characteristics as related to drainage area, active-channel width, and soils in northwestern New Mexico
H. R. Hejl Jr.
1980, Open-File Report 81-64
Regression equations are presented to predict ephemeral streamflow characteristics in the San Juan Basin in northwestern New Mexico. The standard error of estimate for predicting runoff for water year 1978 using drainage area as the independent variable was 152 percent. Indications are that reliable equations for predicating annual runoff can...
Ground water in the carbonate rocks of the Franklin area, Tennessee
Ann Zurawski, C.R. Burchett
1980, Open-File Report 80-410
A study of ground water in the Franklin area, Tennessee, was undertaken to fill a growing need for information on ground-water occurrence in the carbonate rocks of central Tennessee. Fifteen drilling sites were selected that had one or more of the following characteristics: medium-to thick-bedded limestones within 200 feet of...
Determining the availability of sediment-bound trace metals to aquatic deposit-feeding animals
Samuel N. Luoma, D.J. Cain, E.A. Thomson, C. Johansson, E. A. Jenne, G.W. Bryan
1980, Open-File Report 80-341
Physicochemical form affects, by as much as 1000 fold, the uptake rate by deposit-feeding clams of metals bound to sediments. The strength of metal binding to the different sedimentary binding substrates controls this effect. Statistical studies that were spatially intensive (comparing 35 stations in 17 estuaries) and temporally intensive (2...
An oilspill risk analysis for the Kodiak Island (proposed sale 46) Outer Continental Shelf lease area
William B. Samuels, Kenneth J. Lanfear, Anastase Nakassis
1980, Open-File Report 80-175
An oilspill risk analysis was conducted to determine the relative environmental hazards of developing oil in different regions of the Kodiak Island Outer Continental Shelf (OCS) lease area. The study analyzed the probability of spill occurrences, likely paths of oil slicks, and locations of resources vulnerable to spilled oil. The...
Chemical analyses of coal and coal-associated shale samples from the lower part of the Fort Union Formation, Little Snake River coal field, Sweetwater and Carbon counties, Wyoming
Joseph R. Hatch, Ronald H. Affolter
1980, Open-File Report 80-92
As part of a continuing program by the U.S. Geological Survey to collect and analyze representative samples of U.S. coals, 26 coal and 5 coal-associated shale samples were collected from 13 core and rotary-drill holes in the lower part of the Paleocene Fort Union Formation in the Little Snake River...
A homogeneous stochastic model for earthquake occurrences
Anne S. Kiremidjian, Thalia Anagnos
1980, Open-File Report 80-1153
The objective of this study is to develop a probabilistic model for earthquake occurrences with temporal and spatial memory. Stochastic processes are used to characterize both the spatial and temporal dependencies of seismic occurrences along a fault. Currently, only homogeneous space and time transitions are considered. The resulting process however...
