What is Phreeqc used for?
PHREEQC can be used as a speciation program to calculate saturation indices, the distribution of aqueous species, and the density and specific conductance of a specified solution composition.
How to input data in PHREEQC?
The input for PHREEQC is arranged by keyword data blocks. Each data block begins with a line that contains the keyword (and possibly additional data) followed by additional lines containing data related to the keyword. The keywords that define the input data for running the program are listed in table 1.
How do I use Phreeqc on Mac?
To operate PHREEQC, open or double-click on the run phreeqc application. After the brief instruction dialog, you will be prompted to select files for input, output, and database. The input and output files may be stored anywhere on your system, but the database files must remain in the database folder.
How do I download Phreeqc?

An adapted version of Notepad++ will be installed along with phreeqc version 3 by the installer, see the download site.
What is Phreeqc model?
Introduction. PHREEQC (Parkhurst and Appelo, 1999) is a geochemical reaction model that simulates a variety of geochemical processes including equilibrium between water and minerals, ion exchangers, surface complexes, solid solutions, and gases.
How do I run Phreeqc on Mac?
Using PHREEQC with Terminal (Mac)

What is Modflow used for?
MODFLOW is the USGS’s modular hydrologic model. MODFLOW is considered an international standard for simulating and predicting groundwater conditions and groundwater/surface-water interactions.
What type of model is MODFLOW?
modular finite-difference flow model
MODFLOW is the U.S. Geological Survey modular finite-difference flow model, which is a computer code that solves the groundwater flow equation. The program is used by hydrogeologists to simulate the flow of groundwater through aquifers.
What MODFLOW 6?
MODFLOW 6 is an object-oriented program and framework developed to provide a platform for supporting multiple models and multiple types of models within the same simulation.
What is MODFLOW used for?
What does MODFLOW stand for?
NAME modflow – Modular three-dimensional finite-difference ground-water flow model ABSTRACT MODFLOW is a three-dimensional finite-difference ground-water flow model. It has a modular structure that allows it to be easily modified to adapt the code for a particular application.
Who developed MODFLOW?
The program includes proprietary extensions, such as MODFLOW-SURFACT, MT3DMS (mass-transport 3D multi-species) and a three-dimensional model explorer….Visual MODFLOW.
