Floods in Arkansas, magnitude and frequency characteristics through 1968
James L. Patterson
1971, Arkansas Geological Commission Water Resources Circular 11
Techniques are presented for estimating the magnitude and frequency of floods on Arkansas streams. Modern topographic maps now available and computer techniques facilitate in making a comprehensive analysis in which physical and climactic characteristics of river basins are related to flood characteristics at gaging stations. Equations derived from the analysis...
Hydrologic data for Horseshoe Lake, Arkansas and vicinity
A. G. Lamonds
1971, Open-File Report 71-177
During the summer and fall, seepage and evaporation losses from Horseshoe Lake, an oxbow or an 'old river' lake adjacent to the Mississippi River, exceed inflow to the lake, and seasonal declines of 2.5-3.0 feet in the lake level are common. In exceptionally dry years, the minimum lake level has...

Suggested criteria for hydrologic design of storm-drainage facilities in the San Francisco Bay Region, California
Saul Edward Rantz
1971, Open-File Report 71-341
This report presents basic criteria, in the form of tables and graphs, for each of the four methods of hydrologic design most commonly used in the San Francisco Bay region--flood-frequency analysis, Rational Method, unit-hydrograph method, and runoff simulation by means of hydrologic basin modeling. The term "hydrologic design" as used...
The relation of turbulence to diffusion in open-channel flows
Thomas N. Keefer
1971, Open-File Report 72-206
This investigation examines the interrelation between turbulent diffusion, dispersion, and the statistical properties of turbulence in an open-channel flow. The experiments were conducted in a 3. 87- foot wide flume over four boundary roughnesses. The results are from studies made of: (1) the influence of turbulence on the vertical and...
Mathematical ground-water model of Indian Wells Valley, California
R. M. Bloyd Jr., S. G. Robson
1971, Open-File Report 72-41
A mathematical model of the Indian Wells Valley ground-water basin was developed and verified. The alternating-direction implicit method was used to compute the mathematical solution. It was assumed that there are only two aquifers in the valley, one being deep and the other shallow. Where the shallow aquifer occurs, the...
Hydrologic analysis of Mojave River Basin, California, using electric analog model
W. F. Hardt
1971, Open-File Report 72-157
The water needs of the Mojave River basin will increase because of population and industrial growth. The Mojave Water Agency is responsible for providing sufficient water of good quality for the full economic development of the area. The U.S. Geological Survey suggested an electric analog model of the basin as...
The Shublik Formation and adjacent strata in northeastern Alaska description, minor elements, depositional environments and diagenesis
Harry Allison Tourtelot, Irvin L. Tailleur
1971, Open-File Report 71-284
The Shublik Formation (Middle and Late Triassic) is widespread in the surface and subsurface of northern Alaska. Four stratigraphic sections along about 70 miles of the front of the northeastern Brooks Range east of the Canning giver were examined and sampled in detail in 1968. These sections and six-step spectrographic...
Ground-water hydrology of the San Pitch River drainage basin, Sanpete County, Utah
Gerald B. Robinson Jr.
1971, Water Supply Paper 1896
The San Pitch River drainage basin in central Utah comprises an area of about 850 square miles; however, the investigation was concerned primarily with the Sanpete and Arapien Valleys, which comprise about 250 square miles and contain the principal ground-water reservoirs in the basin. Sanpete Valley is about 40 miles...
Ground water for irrigation in the Brooten-Belgrade area, west-central Minnesota
Wayne A. Van Voast
1971, Water Supply Paper 1899-E
Water for irrigation is needed to improve crop yields from sandy soils in the Brooten-Belgrade area. Ground-water supplies of sufficient quantity and suitable quality for irrigation are available in much of the area. Quaternary glacial drift, as much as 300 feet thick, is underlain by Precambrian crystalline rocks and possibly by...
Selected fluvial monazite deposits in the southeastern United States
William C. Overstreet, A. M. White, P. K. Theobald, D. W. Caldwell
1971, Open-File Report 71-222
Farther southwest in Georgia, around Griffin and Zebullon, along streams tributary to the Flint River in the monazite belt the flood plains are generally small and discontinuous, and only about 1 percent of the sediment is gravel. The area between Griffin, Zebullon, and the Flint River is underlain by biotite...
The drainage and glacial history of the Still River Valley, southwestern Connecticut
Woodrow B. Thompson
1971, Open-File Report 71-283
The Still River is located in southwestern Connecticut. From its origin on the New York border, it passes through Danbury and flows northward to its junction with the Housatonic River in New Milford. Interpretation of the Still River's history is based on its surficial geology and bedrock topography. High bedrock...

Mill Creek valley is part of the greater Cincinnati industrial area in southwestern Ohio. In 1964, nearly 30 percent of the water supply in the study area of about 27 square miles was obtained from wells in the glacial-outwash aquifer underlying the valley. Ground-water demand has increased steadily since the...

Orlo A. Crosby
1971, Open-File Report 71-81
Studies of infrared imagery obtained from aircraft at 305- to 1,524- meter altitudes indicate the feasibility of monitoring thermal changes attributable to the operation of thermal-electric plants and storage reservoirs, as well as natural phenomena such as tributary inflow and ground-water seeps, in large rivers. No identifiable sources of ground-water...
