Geophysical framework of the southwestern Nevada volcanic field and hydrogeologic implications
V.J. Grauch, David A. Sawyer, Chris J. Fridrich, Mark R. Hudson
1999, Professional Paper 1608
Gravity and magnetic data, when integrated with other geophysical, geological, and rock-property data, provide a regional framework to view the subsurface geology in the southwestern Nevada volcanic field. The region has been loosely divided into six domains based on structural style and overall geophysical character. For each domain, the subsurface...
Procedures and computer programs for telescopic mesh refinement using MODFLOW
Stanley A. Leake, David V. Claar
1999, Open-File Report 99-238
Ground-water models are commonly used to evaluate flow systems in areas that are small relative to entire aquifer systems. In many of these analyses, simulation of the entire flow system is not desirable or will not allow sufficient detail in the area of interest. The procedure of telescopic mesh refinement allows use of...
