PHRQCGRF - A Computer Program for Graphical Interpretation of PHREEQC Geochemical Transport Simulations
Entry ID: USGS_PHRQCGRF
[ Update this Record ]


Summary
Abstract: PHRQCGRF is a computer program for graphical interpretation of the PHREEQC geochemical transport simulations. PHREEQC is based on an ion-association aqueous model and has capabilities for (1) speciation and saturation-index calculations; (2) batch-reaction and one-dimensional (1D) transport calculations involving reversible reactions, which include aqueous, mineral, gas, solid-solution, surface-complexation, and ion-exchange equilibria, and irreversible reactions, which include specified mole transfers of reactants, kinetically controlled reactions, mixing of solutions, and temperature changes; and (3) inverse modeling, which finds sets of mineral and gas mole transfers that account for differences in composition between waters, within specified compositional uncertainty limits.
