The Geochemist's Workbench- overview

$799 ($699 academic)

The "essential" set of aqueous geochemistry tools that every geochemist should own:

• balance chemical reactions
• create redox-pH and activity diagrams
• calculate solution speciation, mineral saturation, gas fugacities and more
• model ion sorption and surface complexation
• plot Piper, Stiff and other aqueous geochemistry diagrams

$7999 ($6999 academic)

Contains all the tools of GWB Standard, and adds 1D and 2D reactive transport modeling:

• transport by advection, diffusion and dispersion
• fixed and evolving flow rates and patterns
• saturated and unsaturated flow
• permeability constant or varying
• import flow fields as table, or from Modflow models
• heat flow by advection and conduction
• model polythermal flow and reactions
• set internal domain heat sources
• regular or variably spaced (telescoping) grids
• flexible boundary conditions on all sides of the domain
• heterogeneous domains and initial conditions
• easy to use "in-line" tables for specifying node-by-node heterogeneity
• define domain heterogeneity using tables, equations, scripts or compiled functions
