Chemical equilibrium diagrams for ground-water systems/les graphiques de l'équilibre chimique pour les systèmes des eaux souterrainnes
J.D. Hem
1960, International Association of Scientific Hydrology - Bulletin (5) 45-53
Chemical equilibrium in water in contact with calcite is expressed by means of a pH grid overlay on a log-log plot of activities of bicarbonate vs. calcium ions. Solubility of ferrous iron and the solid-phase minerals that would be stable in a solution containing activities of 10 ppm of sulfate...
Mapping mean areal precipitation
D.R. Dawdy, W. B. Langbein
1960, International Association of Scientific Hydrology - Bulletin (5) 16-23
A method is presented for using point mean precipitation data to estimate areal values in regions of high relief. Variation of precipitation with altitude is determined. Local anomalies from this relationship are mapped, and lines of equal anomaly are drawn. By use of the mean relation corrected for the local anomaly, the mean precipitation at...
Areal flood-frequency analysis in a humid region
M. A. Benson
1960, International Association of Scientific Hydrology - Bulletin (5) 5-15
This study was made to define the relation between floods in a humid region and the causative factors that account for their variability. The study covered the basic relationships between peak discharges and hydrologic factors as well as the practical working methods for generalizing the results on a regional basis. Statistical multiple-correlation...
Ground-water hydrology and glacial geology of the Kalamazoo area, Michigan
Morris Deutsch, K.E. Vanlier, P.R. Giroux
1960, Progress Report 23
The Kalamazoo report area includes about 150 square miles of Kalamazoo County, Mich. The area is principally one of industry and commerce, although agriculture also is of considerable importance. It has a moderate and humid climate and lies within the Lake Michigan “snow belt”. Precipitation averages about 35 inches per...
A primer on water
Luna Bergere Leopold, Walter Basil Langbein
1960, Report
When you open the faucet you expect water to flow. And you expect it to flow night or day, summer or winter, whether you want to fill a glass or water the lawn. It should be clean and pure, without any odor.You have seen or read about places where the...
Probability analysis applied to a water-supply problem
Luna Bergere Leopold
1959, Circular 410
The literature on probability techniques applicable to problems in hydrology is abundant but scattered through scientific journals of both hydrology and statistics. Important administrative and judicial decisions presently face water-compact commissions, courts, and water-planning committees. These and other groups might find useful, a brief and simplified discussion of how statistical...
Hydrologic budget of the Beaverdam Creek basin, Maryland
W. C. Rasmussen, Gordon E. Andreasen
1959, Water Supply Paper 1472
A hydrologic budget is a statement accounting for the water gains and losses for selected periods in an area. Weekly measurements of precipitation streamflow, surface-water storage, ground-water stage, and soil resistivity were made during a 2year period, April 1, 1950, to March 28, 1952, in the Beaverdam Creek basin, Wicomico...
Study and interpretation of the chemical characteristics of natural water
John David Hem
1959, Water Supply Paper 1473
The chemical composition of natural water is derived from many different sources of solutes, including gases and aerosols from the atmosphere, weathering and erosion of rocks and soil, solution or precipitation reactions occurring below the land surface, and cultural effects resulting from activities of man. Some of the processes of...
Floods in North and South Dakota: Frequency and magnitude
John A. McCabe, Orlo A. Crosby
1959, Open-File Report 59-80
The magnitude of a flood of a selected frequency for any point in the two states may be determined by methods outlined in this report, with two limitations. These methods are not applicable for regulated streams or for small-drainage areas (in general, less than 100 square miles). The determination of...
History of Imuruk Lake, Seward Peninsula, Alaska
David M. Hopkins
1959, GSA Bulletin (70) 1033-1046
A study of Imuruk Lake, a large, shallow lake in north-central Seward Peninsula, Alaska, illuminates the climatic history of northwestern Alaska and the tectonic history of central Seward Peninsula during Pleistocene and Recent time. Special interest attaches to the older lake sediments, because they contain evidence concerning the climate, fauna, and...
A Summary interpretation of geologic, hydrologic, and geophysical data for Yucca Valley, Nevada test site, Nye County, Nevada
Verl Richard Wilmarth, D.L. Healey, Alfred Clebsch Jr., I.J. Winograd, Isadore Zietz, H. W. Oliver
1959, Trace Elements Investigations 358
This report summarizes an interpretation of the geology of Yucca Valley to depths of about 2,300 feet below the surface, the characteristics features of ground water in Yucca and Frenchman Valleys, and the seismic, gravity, and magnetic data for these valleys. Compilation of data, preparation of illustrations, and writing of...
Ground-water resources of Riverton irrigation project area, Wyoming, with a section on chemical quality of ground water
Donald Arthur Morris, O. M. Hackett, K.E. Vanlier, E. A. Moulder, W. H. Durum
1959, Water Supply Paper 1375
The Riverton irrigation project area is in the northwestern part of the Wind River basin in west-central Wyoming. Because the annual precipitation is only about 9 inches, agriculture, which is the principal occupation in the area, is dependent upon irrigation. Irrigation by surface-water diversion was begum is 1906; water is...
Ground-water resources in the tri-state region adjacent to the Lower Delaware River
Henry C. Barksdale, David W. Greenman, Solomon Max Lang, George Stockbridge Hilton, Donald E. Outlaw
1958, New Jersey Division of Water Policy and Supply Special Report 13
The purpose of this report is to appraise and evaluate the groundwater resources of a tri-state region adjacent to the lower Delaware River that is centered around Philadelphia, Pa., and Camden, N. J., and includes Wilmington, Del., and Trenton, N.J. Specifically, the region includes New Castle County, Del.; Burlington, Camden,...
