Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2021-03-25T00:00:00Z
The USGS assessment and methodology reports cited within this software release require extensive processing using computational methods and modeling. The most demanding aspects of the modeling were performed using publicly available software: SGeMS and GSLIB. This publication releases the FORTRAN source code of 15 supplementary computer programs that are required to perform the more specific aspects of the modeling. Upon downloading a program, the user needs to use a FORTRAN compiler for generating the executable code.
