Changes in the water supply in the Upper Republican Natural Resources District, Southwest Nebraska, from 1952-75
E.G. Lappala
1976, Open-File Report 76-498
Use of ground water for irrigation has increased rapidly in the Upper Republican Natural Resources District in southwestern Nebraska in recent years. The principal aquifer being developed is composed of saturated and gravel of the Ogallala Formation of Tertiary age. Water-level declines of as much as 16 feet (4.9 meters)...

Monitoring irrigated land acreage using Landsat imagery: an application example
William C. Draeger
1976, Open-File Report 76-630
A demonstration of the utility of Landsat imagery for quickly and cheaply estimating irrigated land area was conducted in the Klamath River basin of Oregon. Landsat color composite images, at 1:250,000 scale and acquired on two dates during the 1975 growing season, were interpreted. Irrigated lands were delineated manually, and...
Teton Dam flood of June 1976, Rigby quadrangle, Idaho
Herman A. Ray, Bruce B. Bigelow
1976, Hydrologic Atlas 572
The failure of the Teton Dam caused extreme flooding along the Teton River, Henrys Fork, and Snake River in southeastern Idaho on June 5-8, 1976. No flooding occurred downstream from American Falls Reservoir. The inundated areas and maximum water-surface elevations are shown in a series of 17 hydrologic atlases. The...

Numerical model of the salt-wedge reach of the Duwamish River estuary, King County, Washington
Edmund A. Prych, W.L. Haushild, J.D. Stoner
1976, Professional Paper 990
A numerical model of a salt-wedge estuary developed by Fischer (1974) has been expanded and used to calculate the distributions of salinity, temperature, chlorophyll a concentration, biochemical oxygen demand, and dissolved-oxygen concentration in the Duwamish River estuary, King County, Wash. The model was used to predict the dissolved-oxygen concentrations in...

Machine-assisted analysis of Landsat data in the study of crop-soils relationships
William C. Draeger
1976, Open-File Report 76-603
To date, relatively few studies have dealt with crop-soil interactions as they affect the appearance of agricultural areas on Landsat imagery, and hence crop and soil classification or the analysis of agricultural land use.The Image 100, a computer-based data analysis system which allows an interpreter to interact directly and rapidly with Landsat computer...

Analysis of native water, bed material, and elutriate samples of major Louisiana waterways, 1975
Charles R. Demas
1976, Open-File Report 76-853
The U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, conducted a series of elutriate studies in selected reaches of major navigable waterways of Louisiana. As defined by the U.S. Environmental Protection Agency, an elutriate is the supernatant resulting from the vigorous 30-minute shaking of one part...

Fluid-Inclusion Petrology - Data from Porphyry Copper Deposits and Applications to Exploration
J. Thomas Nash
1976, Professional Paper 907-D
Fluid-inclusion studies of 37 porphyry copper deposits, mainly in the United States, demonstrate that all but 3 evolved through a hydrothermal stage characterized by very high salinities, generally in excess of about 35 weight percent NaCI equivalent. Temperatures of these fluids ranged from about 250 deg to 700 deg C...
Geohydrology of the lowland lakes area, Anchorage, Alaska
Chester Zenone
1976, Water-Resources Investigations Report 76-22
Unconsolidated deposits, chiefly of glacial origin, make up the surficial geologic materials in the Anchorage lowland lakes area , the western part of the Anchorage glacial outwash plain. Postglacial accumulation of peat, commonly 5 to 10 feet thick, and the presence of ground water at or very near the surface...

Examination of images from Nimbus, NOAA and Landsat satellites has revealed a series of lineaments in the earth's surface in Alaska 1000 km or more in length (fig. 1). These lineaments occur as alinements of surface geologic structures, linear valleys or ridges, and linear changes in tonal contrast marking differences...

The structure of a turbulent flow in a channel of complex shape
Hubert Jerome Tracy
1976, Professional Paper 983
Measurements of the Reynolds stresses and the mean motion pattern were made in a uniform turbulent motion in a conduit consisting of a large, nearly square section joined by a smaller rectangular section. The results indicate that the boundary shearing stress is nearly constant over large segments of the boundaries....
