F. E. Senftle, R.M. Moxham, A.B. Tanner
1972, Nuclear Instruments and Methods (104) 485-492
The recent availability of borehole logging sondes employing a source of neutrons and a Ge(Li) detector opens up the possibility of analyzing either decay or capture gamma rays. The most efficient method for a given element can be predicted by calculating the decay-to-capture count ratio for the most prominent peaks...

Equations derived from the analysis...
Mathematical ground-water model of Indian Wells Valley, California
R. M. Bloyd Jr., S. G. Robson
1971, Open-File Report 72-41
A mathematical model of the Indian Wells Valley ground-water basin was developed and verified. The alternating-direction implicit method was used to compute the mathematical solution. It was assumed that there are only two aquifers in the valley, one being deep and the other shallow. Where the shallow aquifer occurs, the...

Ground-water discharge to the streams sustains year-round streamflow in the upper White River basin. This discharge, referred to as ground-water runoff or base runoff, is considered to be an index to the amount of g ound water available for development. A comparison of the variations of groundwater runoff and aquifer...

1971, Water Supply Paper 1893
Mill Creek valley is part of the greater Cincinnati industrial area in southwestern Ohio. In 1964, nearly 30 percent of the water supply in the study area of about 27 square miles was obtained from wells in the glacial-outwash aquifer underlying the valley.
