Geology, water resources and usable ground-water storage capacity of part of Solano County, California
H.G. Thomasson Jr., F. H. Olmsted, E. F. LeRoux
1960, Water Supply Paper 1464
The area described is confined largely to the valley-floor and foothill lands of Solano County, which lies directly between Sacramento, the State capital, and San Francisco. The area is considered in two subareas: The Putah area, which extends from Putah Creek southward to the Montezuma Hills and from the foothills...
Double-mass curves, with a section fitting curves to cyclic data
James K. Searcy, Clayton H. Hardison, Walter B. Langbein
1960, Water Supply Paper 1541-B
The double.-mass curve is used to check the consistency of many kinds of hydrologic data by comparing data for a single station with that of a pattern composed of the data from several other stations in the area The double-mass curve can be used to adjust inconsistent precipitation data. The...
Grid method of determining mean flow-distance in a drainage basin
M.W. Busby, M. A. Benson
1960, International Association of Scientific Hydrology - Bulletin (5) 32-36
The basin characteristics Σal or L ca are useful in hydrologic studies, but existing methods of determining them are either tedious or somewhat inaccurate. The grid method presented herein lessens the amount of tedious labor and provides an accurate measure of either Σal or L ca . An adaptation of the method could be used to compute the...
Variation in surface elevation of the nisqually glacier Mt. Rainier, Washington
A. Johnson
1960, International Association of Scientific Hydrology - Bulletin (5) 54-60
Variation in surface elevations of the Nisqually Glacier has been recorded since 1942 by the annual measurement of three profiles across the glacier, designated as nos. 1, 2, and 3, located 0.5, 1.0, and 1.7 miles respectively from the terminus, at approximate mean elevations of 5,250,6,000, and 6,800 feet. A fourth...
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...
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...
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...
