Geochemist`s Workbench

Version 10.0 - GWB Professional



The Geochemist's Workbench 10.0 Professional edition is the complete suite of tools to meet every practicing geochemist’s needs. GWB Pro is your choice for reactive transport modeling. One-dimensional and two-dimensional simulations of reactive transport in single and dual-porosity media, including bioreaction and migrating colloids, are a snap. Then animate your results and create video clips with a few clicks. GWB Pro's advanced algorithms and multithreaded design make it ideal for simulating the fate and transport of contaminants in flowing ground and surface water. In addition to reactive transport, GWB Pro models kinetic and equilibrium reaction in multicomponent systems, calculates Eh-pH and activity diagrams, and creates a spectrum of specialty plots.You can balance reactions, calculate equilibrium constants, and create powerful geochemical spreadsheets.


Programs X1t and X2t model reactive transport in one and two dimensions. The models account for:

  • Advection, dispersion, and diffusion.
  • Uniform or heterogeneous medium properties.
  • Dual porosity (stagnant zone) effects.
  • Heat transfer by advection and conduction.


X1t and X2t can incorporate any combination of equilibrium and kinetic reactions:

  • Mineral precipitation and dissolution.
  • Gas transfer.
  • Complexation and dissociation.
  • Sorption and desorption.
  • Redox transformation.
  • Catalysis and enzymes.


Migrating colloids are a critical vector for transport of radionuclides, heavy metals, and other contaminants. The GWB handles them with ease:

  • Any complexing surface can form a colloid.
  • The colloid and its surface complexes migrate by advection and dispersion.
  • Colloid mobility may vary in time and space, according to a user-supplied function.


Models can account for reactions catalyzed by microbial activity:

  • Pure culture and mixed communities.
  • Population growth and decay.
  • Thermodynamic effects.


GWB Pro is built from the ground up for dual porosity modeling:

  • Each nodal block divided into free-flowing and stagnant fractions.
  • You specify the geometry and characteristic dimensions of the stagnant zones.
  • The apps account for species diffusion and heat conduction into and out of the stagnant zones.
