Gordon Whitney Weir
1976, Open-File Report 76-193
Crossbedding in sandstone units is the most conspicuous sedimentary structure of the Potomac Formation in Fairfax County, Virginia. Most sets of crossbeds are a few feet thick and several feet wide and tens of feet long. Trough sets are dominant, but planar sets are also common. Dip directions of crossbeds...

Keith Robinson, C. M. McDougal, S.K. McDanal, Theodore Billings
1976, Miscellaneous Field Studies Map 773-J
A geochemical survey was conducted in the McCarthy quadrangle Alaska, to identify areas containing anomalous concentrations of various metallic and nonmetallic elements. This study incorporates the results of analyses for molybdenum from 825 rock samples collected in the quadrangle, and analyzed by the U.S. Geological Survey between 1961 and 1976...

Lakes Marion-Moultrie stream system investigation, South Carolina : Part II-Simulation Studies
H.H. Jeffcoat, M.E. Jennings, D.L. Collins, J.O. Shearman
1976, Water-Resources Investigations Report 76-11
A stream-reservoir model was developed to simulate the operation of the Lakes Marion-Moultrie, South Carolina, reservoir system. The reservoir system is operated under the assumption of a 3-day prior knowledge of inflows. This information is attainable from the ooperational reservoir-inflow forecasting model developed in the Part I report. The model,...
Mean annual runoff in the upper Ohio River basin, 1941-70, and its historic variation
Robert M. Beall
1976, Open-File Report 76-384
A map of the Ohio River basin above the Muskingum River shows patterns of mean annual runoff for the climatologic and hydrologic reference period, 1941-70. The primary data base consisted of 98 long-term gaging-station records collected within this 27,300-square-mile headwater area of the Ohio River basin. Supplemental information was derived...
15/16 ips Operation of the Precision Instrument Company Model P15100 tape recorder to record the standard (30 Hz) NCER seismic data multiplex system
Jerry P. Eaton
1976, Open-File Report 76-252
In recent months the need has arisen to record special seismic networks consisting of a dozen or more standard NCER seismic systems telemetered to a central collection point on a reliable, portable, low-power tape recorder. Because of its simplicity and the ease with which it can be adapted for the...
Notes on a broad-band variant of the NCER seismic data multiplex system for use with field tape recorders
Jerry P. Eaton
1976, Open-File Report 76-87
Tests of the standard NCER multiplex system recorded and played back on both the Bell and Howell 3700B (about 0.1% tape speed variation) and on the Sony TC-126 cassette recorder (about 1% tape speed variation) showed that subtractive compensation employing a reference frequency multiplexed on the data track was remarkably...
Flood discharges of streams in New Mexico as related to channel geometry
Arthur G. Scott, J.L. Kunkler
1976, Open-File Report 76-414
This report describes the results of a study relating flood characteristics to the reference width of the channel.Data from 79 gaging stations, which would provide estimates of floods of a 10-year recurrence interval and at which channel geometry could be adequately measured in the field, were used in these analyses....

Statistical analysis of water-level, springflow, and streamflow data for the Edwards Aquifer in south-central Texas
Celso Puente
1976, Open-File Report 76-393
Water-level, springflow, and streamflow data were used to develop simple and multiple linear-regression equations for use in estimating water levels in wells and the flow of three major springs in the Edwards aquifer in the eastern San Antonio area. The equations provide daily, monthly, and annual estimates that compare very...
