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...
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...
Channel erosion surveys along TAPS route, Alaska, 1976
Paul F. Doyle, Joseph M. Childers
1976, Open-File Report 77-170
Channel surveys were made along the TAPS route during 1976 at the same 27 sites that were surveyed in 1975. One additional site was put under surveillance in 1976. Except for construction changes wrought by installation of the pipeline, most of the sites surveyed showed very little change since the...
Modeling coliform-bacteria concentrations and pH in the salt-wedge reach of the Duwamish River Estuary, King County, Washington
W.L. Haushild, Edmund A. Prych
1976, Open-File Report 76-415
Total- and fecal-coliform bacteria, plus pH, alkalinity, and dissolved inorganic carbon are water-quality parameters that have been added to an existing numerical model of water quality in the salt-wedge reach of the Duwamish River estuary in Washington. The coliform bacteria are modeled using a first-order decay (death) rate, which is...
Landslide problems at West Valley Nuclear Service Center, New York: An assessment and recommendations for study
Robert W. Fleming
1976, Open-File Report 76-661
Problems due to landslides prompted a visit to the West Valley Nuclear Service Center (WVNSC) near Springville, New York, on March 15 and 16, 1976. From this visit a report was prepared and contains the following: An assessment of the landslide conditions. An assessment of the immediacy of the landslide problems. A suggested study program...
Depositional environments as a guide to uranium mineralization in the Chinle Formation, San Rafael Swell, Utah
Robert Lupe
1976, Open-File Report 76-283
Uranium deposits in the San Rafael Swell are related to sedimentary depositional environments in the Triassic Chinle Formation. The sedimentary textures resulting from depositional processes operating in lower energy environments appear to have influenced uranium mineralization. The Chinle consists of three fining-upward, fluvial-lacustrine sequences. Uranium mineralization is concentrated in the...
Interpretation and description of seismic data from Lower Cook Inlet, Alaska
Michael A. Fisher
1976, Open-File Report 76-561
A coarse grid of 480 kilometres of seismic lines was collected in lower Cook Inlet, Alaska between Homer on the north and Cape Douglas on the south. Paper and mylar copies of the seismic sections and shot point maps are available to the public from NOAA in Boulder, Colorado.The seismic...
Discharge data at water-quality monitoring stations in Arkansas, 1976 water year
R.K. Knott
1976, Open-File Report 77-401
Streamflow data are presented for a network of water-quality monitoring stations operated by the Arkansas Department of Pollution Control and Ecology. Discharge on days of sampling was determined for about 75 of the sites. A summary of those discharges for the water year 1976 is tabulated. Several discharges for miscellaneous...
Ground-water records for southeastern Oklahoma : Part 1, records of wells, test-holes, and springs
John S. Havens, DeRoy L. Bergman
1976, Open-File Report 76-889
The U. S. Geological Survey has collected data on Oklahoma's ground-water resources since 1934. Most of these data were collected as part of specific ground-water studies conducted in cooperation with various Federal, State, and local agencies. Although a large amount of ground-water data have been published, they are scattered through a...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: October 1976
J.B. Townshend, J.E. Papp, M.J. Moorman, C.E. Deadmon, S.P. Tilton
1976, Open-File Report 76-300-J
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...

Documentation of programs that compute 1) quasi-static tilts produced by an expanding dislocation loop in an elastic and viscoelastic material, and 2) surface shear stresses, strains, and shear displacements produced by screw dislocations in a vertical slab with modulus contrast
Stuart McHugh
1976, Open-File Report 76-484
The material in this report can be grouped into two categories: 1) programs that compute tilts produced by a vertically oriented expanding rectangular dislocation loop in an elastic or viscoelastic material and 2) programs that compute the shear stresses, strains, and shear displacements in a three-phase half-space (i.e. a half-space...
