Streamflow characteristics of the Joplin area, Missouri
John Skelton
1977, Open-File Report 77-605
Low-flow and peak-flow frequency data and flow-duration-data, based on records from 21 gaging stations in the Joplin area of southwestern Missouri, are presented. Generalized equations and graphs based on gaging-station records are-shown so that estimates of frequency data and the effects of urbanization on peak flows can be made at...

Analysis of runoff from small drainage basins in Wyoming
Gordon S. Craig, James G. Rankl
1977, Open-File Report 77-727
A flood-hydrograph study has defined the magnitude and frequency of flood volumes and flood peaks that can be expected from drainage basins smaller than 11 square miles in the plains and valley areas of Wyoming. Rainfall and runoff data, collected for 9 years on a seasonal basis (April through September),...
Preliminary data on some Precambrian deposits of zinc-copper-lead sulfides and zinc spinel (granite) in Colorado
Douglas M. Sheridan, William H. Raymond
1977, Open-File Report 77-607
Precambrian sulfide deposits in the Southern Rocky Mountains in Colorado are being studied and re-evaluated according to geologic concepts which were developed in recent years in other parts of the world during successful research regarding economic massive sulfide deposits. These studies, initiated in 1974 in Colorado by the U.S. Geological...
Documentation for subroutine REDUC3, an algorithm for the linear filtering of gridded magnetic data
Richard J. Blakely
1977, Open-File Report 77-784
Subroutine REDUC3 transforms a total field anomaly h1(x,y) , measured on a horizontal and rectangular grid, into a new anomaly h2(x,y). This new anomaly is produced by the same source as h1(x,y) , but (1) is observed at a different elevation, (2) has a source with a different direction of...
Interpretation of an aeromagnetic anomaly in McMullen and Live Oak counties, Texas
Joseph S. Duval, R.A. Martin
1977, Open-File Report 77-768
An anomaly about 300 gammas in amplitude has been observed in data from an aerial magnetic survey flown over parts of Duval, Live Oak, McMullen, and Webb Counties, Tex. A two-and-one-half-dimensional model was used to iterpret the data, and the anomaly is apparently caused by a large mafic body centered...

Analog-model analysis of regional three-dimensional flow in the ground-water reservoir of Long Island, New York
Rufus T. Getzen
1977, Professional Paper 982
A three-dimensional analog model of the ground-water system beneath Long Island, N.Y., provides a practical means for studying anisotropic flow on a regional scale. Constructional and operational techniques influence the simulation almost as much as model design does. Usefulness and accuracy of the model depend on (1) inherent and practical...
Factors limiting the sensitivity and dynamic range of a seismic system employing analog magnetic tape recording and a seismic amplifier with adjustable gain settings and several output levels
Jerry P. Eaton, John R. Van Schaack
1977, Open-File Report 77-224
In the course of modernizing the low-speed-tape-recorder portable seismic systems and considering the possibilities for the design of a cassette-tape-recorder seismic refraction system, the factors that limit the sensitivity and dynamic range of such systems have been reviewed. These factors will first be stated briefly, and then their influence on...
