PHAST: A Computer Program for Simulating Ground-Water Flow, Solute Transport, and Multicomponent Geochemical Reactions
Entry ID: USGS_PHAST
[ Get Service ]
[ Update this Record ]


Summary
Abstract: The computer program PHAST simulates multi-component, reactive solute transport
in three-dimensional saturated ground-water flow systems. PHAST is a versatile
ground-water flow and solute-transport simulator with capabilities to model a
wide range of equilibrium and kinetic geochemical reactions. The flow and
transport calculations are based on a modified version of HST3D that is
restricted to constant fluid density and constant temperature. The geochemical
reactions are simulated with the geochemical model PHREEQC, which is embedded
in PHAST.

PHAST is applicable to the study of natural and contaminated ground-water
systems at a variety of scales ranging from laboratory experiments to local and
regional field scales. PHAST can be used in studies of migration of nutrients,
inorganic and organic contaminants, and radionuclides; in projects such as
aquifer storage and recovery or engineered remediation; and in investigations
of the natural rock-water interactions in aquifers. PHAST is not appropriate
for unsaturated-zone flow, multiphase flow, density-dependent flow, or waters
with high ionic strengths.
