Methods for regional assessment of geothermal resources
P. Muffler, R. Cataldi
1978, Geothermics (7) 53-89
A consistent, agreed-upon terminology is prerequisite for geothermal resource assessment. Accordingly, we propose a logical, sequential subdivision of the "geothermal resource base", accepting its definition as all the thermal energy in the earth's crust under a given area, measured from mean annual temperature. That part of the resource base which...

Appraisal of the water resources of Death Valley, California-Nevada
Glenn Allen Miller
1977, Open-File Report 77-728
The hydrologic system in Death Valley is probably in a steady-state condition--that is, recharge and discharge are equal, and net changes in the quantity of ground water in storage are not occurring. Recharge to ground water in the valley is derived from interbasin underflow and from local precipitation. The two...
