Preliminary report on some factors affecting shotpoint efficiency
W. H. Jackson, J. H. Healy
1964, Crustal Studies Technical Letter 17
A study of first-arrival amplitudes from 6 water shotpoints and 7 drill-hole shotpoints in parts of central and western United States indicate a variation of over 100 to 1 between the best and poorest shotpoints. Water shotpoints are, in general, superior to drill-hole shotpoints; however, one drill-hole shotpoint produced higher...

There is no generally accepted definition of geographic center, and no completely satisfactory method for determining it. Because of this, there may be as many geographic centers of a State or country as there are definitions of the term. The geographic center of an area may be defined as the...
Specific yield - laboratory experiments showing the effect of time on column drainage
R.C. Prill, A.I. Johnson, D. A. Morris
1964, Report
The increasing use of ground water from many major aquifers in the United States has required a more thorough understanding of gravity drainage, or specific yield. This report describes one phase of specific yield research by the U.S. Geological Survey's Hydrologic Laboratory in cooperation with the California Department of Water...
