Ground-water levels in observation wells in Oklahoma, 1961-62
P.R. Wood, M.D. Moeller
1964, Open-File Report 64-169
The investigation of the ground-water resources of Oklahoma by the U. S. Geological Survey in cooperation with the Oklahoma Water Resources Board includes a continuing program to collect records of water levels in selected observation wells on a systematic basis. These water-level records: (1) provide an index to available ground-water...

Hydrology and hydrogeology of Navajo Lake, Kane County, Utah
Milton Theurer Wilson, Harold E. Thomas
1964, Professional Paper 417-C
Navajo Lake, whose entire outflow disappears underground, is on the high Markagurit Plateau where the average annual precipitation is more than 30 inches. It nestles among the headwaters of several streams that flow into arid regions where competition for municipal, industrial, and irrigation water sup- plies is very keen. Several...
Hidden Recharge
J. H. Feth
1964, Ground Water (2) 14-17
“Hidden recharge” is defined as subsurface percolation of water from basin‐margin mountains directly into aquifers of the valley basins. It is an important, and sometimes neglected, item in hydrologic equations. Locally, geologic conditions permit inter‐basin circulation of ground water. The concept that ground‐water basins necessarily terminate at the contact between...
The international hydrological decade
R. L. Nace
1964, Eos, Transactions, American Geophysical Union (45) 413-421
Work toward establishing a program of international cooperative studies in scientific hydrology began about 4 years ago, and the IHD (International Hydrological Decade) will begin under international auspices in January 1965. This program will be highly important for hydrology and hydrologists, and it should contribute greatly to human welfare in the future. Fortuitously, the opening year...
Geohydrologic analogies between the Jordan Valleys of Utah and the holy land
Edward Bradley
1964, International Association of Scientific Hydrology - Bulletin (9) 12-23
The biblical Jordan River Valley, which extends from Lake Tiberias (the Sea of Galilee) to the Dead Sea, is decidedly similar to the Jordan River Valley of Utah, which joins Lake Utah and Great Salt Lake. Both Jordan Rivers drain relatively large fresh-water lakes and also are major sources of discharge into large salty lakes that have no outlets to the ocean.The...
Sedimentology: general introduction and definitions : fluvial sediment and channel morphology
Roger G. Wolff, Paul C. Benedict
1964, Report
Sedimentology, the study of sedimentary rocks and the processes by which they are formed, includes and is related to a large number of phenomena. Sedimentology includes the five fundamental processes defined by the term sediaentation --weathering, erosion, transportation, deposition and diagenesis. Sedimentology shares with geomorphology the study of the surface...
Soil mechanics and soil physics symbols and nomenclature useful in hydrologic studies
A.I. Johnson
1964, Report
The study of hydrology requires an interdisciplinary approach, incorporating knowledge from fields such as engineering, geology, chemistry, and agriculture. With increasing frequency, the hydrologist finds it necessary to study the literature of the soil mechanics and soil physics disciplines for assistance in the solution of hydrologic problems. Because of the inter-relation between hydrology and soil mechanics...
Hydrologic factors pertinent to ground‐water contamination
R. Brown
1964, Groundwater (2) 5-12
Predictions of where and how a fluid waste may travel from disposal site to the water table require detailed information on the physical characteristics, location, and extent of all pervious and impervious materials in the unsaturated zone. Principles concerning the flow system in the unsaturated zone indicate the importance of choice of...
