    • PHREEQC files for geochemical simulations in Horn Creek, Grand Canyon, AZ

    Metadata Updated: July 6, 2024

    PHREEQC files included in this ScienceBase product were used to interpret changes in water quality within the Horn Creek watershed of Grand Canyon for the associated publication. PHREEQC is a publicly available software for geochemical modeling and the software can be downloaded at https://www.usgs.gov/software/phreeqc-version-3. An accompanying report (Parkhurst and Appelo, 2013) serves as the formal documentation for PHREEQC.The wateq4f database (Ball and Nordstrom, 1991) was used, without modification, for the PHREEQC simulation. Text files of the input and output information from PHREEQC are included to document information without needing the PHREEQC program.
