Ground‐water inventory in the Upper Gila River Valley, New Mexico and Arizona: Scope of investigation and methods used
S.F. Turner, L.C. Halpenny
1941, Eos, Transactions, American Geophysical Union (22) 738-744
The Division of Ground Water of the Geological Survey, United States Department of the Interior, has been making an inventory of the water‐resources of the upper Gila River since January 1, 1940. Funds for the project are furnished under a cooperative agreement with the Arizona State Water Commissioner, supplemented by...
Coefficients of storage and transmissibility obtained from pumping tests in the Houston District, Texas
C. E. Jacob
1941, Eos, Transactions, American Geophysical Union (22) 744-756
An investigation of the ground‐water supply of the Houston District, in Texas, has been in progress since December, 1930, under the general direction of O. E. Meinzer, Geologist‐in‐Charge of the Division of Ground Water of the Geological Survey. The Houston District, as the term is used here, comprises all of...
Fluctuations of water‐level in wells in the Los Angeles basin, California, during five strong earthquakes, 1933–1940
G.A. LaRocque Jr.
1941, Eos, Transactions, American Geophysical Union (22) 374-386
Numerous ground‐water hydrologists have obtained records of water‐level surges in wells during earthquakes and of heightened or lowered levels after those earthquakes. Many of these surges and changes of level are undoubtedly direct effects of the several earthquake‐waves that are recorded on seismographs. Thus, water‐level recorders on observation‐wells promise to...
Report of committee on underground waters, 1940–41
David G. Thompson
1941, Eos, Transactions, American Geophysical Union (22) 948-950
The membership of the Committee during the past year has continued as it was a year ago [see Trans. Amer. Geophys. Union, p. 433, 1940].During a large part of the year, particularly during the last few months, many of the members of the Committee have been engaged in activities more...
Depth of active solution by ground‐waters in the Pecos Valley, New Mexico
Arthur M. Morgan
1941, Eos, Transactions, American Geophysical Union (22) 779-783
The Pecos River Drainage‐Basin is underlain by a thick series of Permian rocks consisting largely of limestone, gypsum (or anhydrite), and halite. The beds have a regional eastward or southeastward dip of 40 to 80 feet to the mile and successively younger beds are exposed at the surface from west...
Ground‐water dams created by faulting of alluvial sediments in the hurricane fault‐zone, Utah
H. E. Thomas
1941, Eos, Transactions, American Geophysical Union (22) 775-778
Ground‐water dams are recognized in the unconsolidated sediments of two intermontane valleys in southwestern Utah. Parowan Valley is about 30 miles long and has a general northeasterly trend; Cedar City Valley lies west and south of Parowan Valley, is somewhat larger, and has a more nearly north‐south trend. Great accumulations...
Report of committee on glaciers, 1940–41
Francois E. Matthes
1941, Eos, Transactions, American Geophysical Union (22) 1006-1011
The personnel of the Committee is now as follows: Harry Fielding Reid, Professor Emeritus of Geology, Johns Hopkins University, 608 Cathedral Street, Baltimore, Maryland; William H. Hobbs, Professor Emeritus of Geology, University of Michigan, Ann Arbor, Michigan; Lawrence Martin, Chief of the Division of Maps, Library of Congress, Washington, D.C.;...
Factors producing a nine‐year decline in ground‐water levels in Scott County, Kansas
H. A. Waite
1941, Eos, Transactions, American Geophysical Union (22) 772-775
In the south‐central part of Scott County, Kansas, there is an area of shallow water‐table in which the ground‐water levels have declined steadily since 1932 (Fig. 1). In this area water has been withdrawn from wells for irrigation in increasing amounts during the last decade and the precipitation has been...
Report of committee on the chemistry of natural waters, 1840–41
C. S. Howard
1941, Eos, Transactions, American Geophysical Union (22) 901
The membership of the Committee during the past year was as follows: I. A. Dennison. Bureau of Standards; C. S. Scofield, Department of Agriculture; D. G. Thompson, Geological Survey; T. G. Thompson, University of Washington, Seattle, Washington; and C. S. Howard, United States Geological Survey, Washington, D.C. (Chairman)....
The quicksilver deposits of the Terlingua region, Texas
Clyde P. Ross
1941, Economic Geology (36) 115-142
Texas is second among quicksilver-producing States because of the Terlingua region, in the Big Bend of the Rio Grande. This region contains Cretaceous strata, largely calcareous, which grade upward into Tertiary volcanics, locally without break. The strata are cut by numerous intrusions, largely alkalic, and are extensively folded and faulted.Many...
The effect of a well on the flow of a nearby stream
Charles V. Theis
1941, Eos, Transactions, American Geophysical Union (22) 734-738
In many irrigation‐districts where the supplies of surface‐water from a stream nave been entirely appropriated, pumping from wells has been resorted to in order to supplement the surface‐supply. Where the pumps are near a stream that has a flow during the irrigation‐season, either because of normal ground‐water flow or because...
Determination of small quantities of fluoride in water: A modified zirconium-alizarin method
W.L. Lamar, C.G. Seegmiller
1941, Industrial And Engineering Chemistry Analytical Edition (13) 901-902
The zirconium-alizarin method has been modified to facilitate the convenient and accurate determination of small amounts of fluoride in a large number of water samples. Sulfuric acid is used to acidify the samples to reduce the interference of sulfate. The pH is accurately controlled to give the most sensitive comparisons....
