Appendix B—Notes on the permeability coefficient and its units
V.C. Fishel
1946, Eos, Transactions, American Geophysical Union (27) 256-269
In the development of terms and units for a new science such as ground‐water hydrology, which is based on physics, it would seem fitting to adopt the terminology that has become standard in other branches of physics such as heat and electricity. Darcy's law has its counterpart in similar laws...
Report of the Research Committee on Runoff, 1945–46
R. W. Davenport
1946, Eos, Transactions, American Geophysical Union (27) 876-878
The variety of usage and even the confusion in the nomenclature and terminology of some fields of hydrology have been often remarked. The Committee on Runoff conceived the idea that it would be profitable to consider some of the terms which are especially pertinent to the field of runoff. That...
General principles of artificial ground-water recharge
O. E. Meinzer
1946, Economic Geology (41) 191-201
The natural subterranean reservoirs formed by the porous and permeable rocks differ from surface reservoirs chiefly in that they have complex structure and great internal resistanc• to the How of water. Their full utilization requires systematic development based on the geology and hydrology of the aquifer and the principles of...

A frequency‐method of evaluating ground‐water levels
Lyman C. Huff
1943, Eos, Transactions, American Geophysical Union (24) 573-580
Water‐levels in wells, which are utilized by the hydrologist as a measure of ground‐water storage, customarily are measured in terms of distance below a convenient measuring point and expressed with reference to a fixed datum. Datum‐planes or surfaces of several types have been used—each serving some particular purpose advantageously. These...
A method for determining transmissibility‐ and storage‐coefficients by tests of multiple well‐systems
Leland K. Wenzel, A.L. Greenlee
1943, Eos, Transactions, American Geophysical Union (24) 547-564
Ground‐water has long been recognized as one of our important natural resources, but only in about the last 20 years has concentrated effort been made to place ground‐water hydrology on a quantitative basis. The quantitative approach to ground‐water work has been brought about largely through the leadership of O. E....

Appendix B—The work of the Geological Survey and cooperating state agencies on ground water for war purposes
O. E. Meinzer
1943, Article
The very large service which the geologists and engineers trained in ground‐water hydrology are rendering in this country in the prosecution of the war is due largely to the effective organization for this purpose. The Federal agency in which this service centers is the Water Resources Branch of the United...
Appendix C—Report on research in the field of ground water being conducted by oil companies
N.A. Rose
1943, Eos, Transactions, American Geophysical Union (24) 420-421
In view of the shortness of time since the appointment of the writer to the Committee on Ground Water this report is confined to the technology and problems in the Gulf Coast Oil Province. Of course, many of the methods and practices would apply to most parts of the country...
Monthly evapo‐transpiration losses from natural drainage‐basin
Walter B. Langbein
1942, Eos, Transactions, American Geophysical Union (23) 604-614
With limited restrictions the hydrologic cycle in a given area may be expressed essentially as follows: P = (R + E + ΔFm) in which P represents the precipitation during a given period, R that portion which has reached or will reach the stream‐channel either through surface or subsurface paths,...
Report of Committee on Underground Waters, 1941–42
David G. Thompson
1942, Eos, Transactions, American Geophysical Union (23) 467-468
So many ground‐water hydrologists are engaged on problems relating directly to the war that the usual annual inquiry for information as to projects that deserve review in the annual report of the Committee on Underground Waters brought relatively little response. It is in part for this reason, but also in...
Ground‐water studies in the Southwest
O. E. Meinzer
1942, Eos, Transactions, American Geophysical Union (23) 6-9
Geologists are concerned with the rock‐systems that form the crust of the Earth. The groundwater geologists are concerned with the rock‐systems specifically because the open spaces which the rocks contain serve as reservoirs and conduits for water—water which performs a large part of the geologic work that is in progress...
General geology and ground-water resources of the island of Maui, Hawaii

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...

Ground‐water recharge in areas of deep water‐table in the Great Plains
R.C. Cady
1940, Eos, Transactions, American Geophysical Union (21) 570-574
It is unanimously agreed, I think, that of the water which falls upon the Earth's surface, a part runs off toward the sea, a part is at least temporarily detained, a part of it evaporates, and a part sinks beneath the ground‐surface. But among students of that water which sinks...
