| Description: | Miscellaneous Paper Abstract: In situ bulk densities and water contents of unconsolidated materials have determined from geophysical logs obtained from borings in three separate geologic environments: desert alluvium, river alluvium, and loess. The geophysical logs used in the property determinations were natural gamma, gamma-gamma, neutron, and caliper. The geophysical (field) bulk densities and water contents were derived at depth intervals corresponding to sampled intervals where similar property data from laboratory analyses were available for comparisons. The field bulk densities ranged from about 5 percent lower to 11 percent higher and had an overall average of 1 percent higher than the laboratory bulk densities. The field water contents ranged from about 12 percent lower to 18 percent higher with an overall average of about 6 percent higher than the laboratory water contents. |
