Review of Existing and Potential Test Sites in Areas 18, 19, and 20, Pahute Mesa, Nevada Test Site

Abstract: "Recent request for new sites has prompted an overall review of the Pahute Mesa area. The criteria used in this review are that the geology must be favorable and that horizontal spacing of emplacement holes being developed should be 2.5 to 3 times hole depth. The review shows that current emplacement requirements have exhausted available explored sites and have effectively eliminated 90 percent of the blocks of ground geologically favorable for chambered sites."

Value of Desalted Water for Irrigation

From Introduction: "This report contains the results of a research study on the "Value of Desalted Water for Irrigation" undertaken in January 1967 by the Bureau of Reclamation and the Saline Water, United Sates Department of the Interior. The objectives of the study were: a. To determine, through application of desalting techniques, the costs and benefits associated with the progressive decreases in the salinity of irrigation water supplies. b. To identify the possible means of introducing desalted water into irrigation supply systems. To relate current desalting technology to potential applications in agriculture."

Summary: "This appendix presents the procedures for digital implementation of the segmented tire model, developed in the basic report for an analog computer. Two procedures are required: (a) determination of the segment spring coefficient from measured load-deflection test results, and (b) computation of the resultant force vector transmitted to the axle. Digital programs for both procedures were written in Fortran IV for a GE-420 system, and are included" (p. xi).
