James M. Hill
1979, Open-File Report 79-1570
A stratigraphic study of the Monterey Group in the East San Francisco Bay Region, California, indicates that a depositional basin began to subside in early to middle Miocene time. The Miocene sea transgressed from the west or southwest, and the area subsided to a possible water depth of 500 to...

F.L. Stroman
1979, Open-File Report 79-509
The collection of hydrologic data by the U.S. Geological Survey in the Mountain Creek watershed began on March 9, 1925, with the establishment of a stream-gaging station located about 2.5 miles upstream from the present site of Mountain Creek Lake Dam. The stream-gaging station was discontinued on July 5, 1933....
Ground-water quality in selected areas of Wisconsin
S. M. Hindall
1979, Open-File Report 79-1594
Analysis of 2,071 ground-water samples from 970 wells throughout Wisconsin indicate large variations in ground-water quality. Ground water in Wisconsin is generally suitable for most uses, but in some areas concentrations of chemical constituents exceed recommended drinking-water standards. Iron, manganese, and nitrate commonly exceed recommended drinking-water standards and dissolved solids,...

1979, Water-Resources Investigations Report 79-16
A study is being made to determine the occurrence and distribution of pesticides in the agricultural drains for approximately 3/4 million irrigated acres in the southeastern desert area of California. This report describes the results of the first year of sampling and analyzing (1) water in the drains , (2)...
Ground-water availability in parts of the Chicopee and Mill River basins, near Wilbraham, Massachusetts
David F. Delaney
1979, Water-Resources Investigations Report 79-72
Ground water in the Wilbraham area occurs in glacial drift and in underlying bedrock. Stratified sand and gravel deposits form the principal unconsolidated aquifers. These aquifers are generally less than 50 feet thick in most of the study area; however, an area in north-central Wilbraham, near the Chicopee River, is...
Urban stormwater data management system with applications to south Florida studies
Robert A. Miller, W. Harry Doyle Jr., Larry D. Wilson
1979, Water-Resources Investigations Report 79-93
A data management system was developed to store and retrieve urban stormwater data collected from four small urban basins in south Florida. The system is event oriented in that all data from one storm are stored together on the computer file. The data include descriptive information about the storm and...
The use of Vacutainer tubes for collection of soil samples for helium analysis
Margaret Hinkle, James E. Kilburn
1979, Open-File Report 79-1441
Measurements of the helium concentration of soil samples collected and stored in Vacutainer-brand evacuated glass tubes show that Vacutainers are reliable containers for soil collection. Within the limits of reproducibility, helium content of soils appears to be independent of variations in soil temperature, barometric pressure, and quantity of soil moisture...

Palladium, platinum, and rhodium concentrations in mafic and ultramafic rocks from the Kizildag and Guleman areas, Turkey, and the Faryab and Esfandagheh-Abdasht areas, Iran
Norman J. Page, Tandogan Engin, Joseph Haffty
1979, Open-File Report 79-840
The Kizildag and Guleman areas, Turkey, and the Faryab and Esfandagheh-Abdasht areas, Iran, have produced chromite from ophiolite complexes consisting of harzburgite tectonite, dunite tectonite containing chromitite, pyroxenite, wehrlite, and gabbro. Forty-six samples from these complexes were analyzed in order to investigate the possibility of platinum-group metals being present that...

Water-quality investigation of the Caney Creek watershed, northeast Arkansas
T.E. Lamb, G. Newsom
1979, Open-File Report 79-1064
The results of a 1-year study, in 1977-78, of surface-water quality in the Caney Creek watershed are presented to document conditions before implementation of Soil Conservation Service programs. Analyses of samples collected at two sites shows that water in Caney Creek and Caney Creek Ditch is of good quality with...

Hydrologic data, 1974-77, Stovepipe Wells Hotel area, Death Valley National Monument, Inyo County, California
Charles Edwin Lamb, D.J. Downing
1979, Open-File Report 79-203
Ground-water levels in most wells did not change significantly from 1974 to 1977 in the Stovepipe Wells Hotel area. The average water-level decline was less than 0.10 foot between August 1974 and August 1977 in 10 observation wells. Water-level contours show a depression centered on the two pumping wells, but...
HYPOELLIPSE: A computer program for determining local earthquake hypocentral parameters, magnitude, and first motion pattern
John C. Lahr
1979, Open-File Report 79-431
HYPOELLIPSE is a computer program for determining the hypocenters of local or near regional earthquakes and for each event the ellipsoid which encloses the one standard deviation region. Traveltimes are determined from a horizontally layered crustal structure or from a linear increase of velocity with depth. Arrival times for the...

David Dell Harris, Larry L. Hubbard, Lawrence E. Hubbard
1979, Open-File Report 79-553
A method for estimating the magnitude and frequency of floods is presented for unregulated streams in western Oregon. Equations relating flood magnitude to basin characteristics were developed for exceedance probabilities of 0.5 to 0.01 (2- to 100-year recurrence intervals). Separate equations are presented for four regions: Coast, Willamette, Rogue-Umpqua, and...
