The calculation can be performed by the following methods:

• Finite-Element-Method (CONTAM-FE)
• Random-Walk-Method (CONTAM-RW)

Capabilities:

• Import of the steady-state groundwater data, soil colors, etc. from the computer program GGU-2D-SSFLOW 
• Consideration of convection, diffusion, dispersion, adsorption and decay 
• Generator for boundary conditions 
• Consideration of seepage lines and unsaturated zones 

Evaluation and graphical visualization of analysis results using the supplementary program GGU-PLGW: 

• Visualization of concentration distributions in any section 
• Visualization of substance concentration as a profile for individual system nodes 
• Visualization of substance propagation at user-definable times, e.g. as normal, color-filled or 3D contours 
• Animated, on-screen visualization of substance propagation with time 
• User-designed output sheet 
• Print or copy screen sections, e.g. for transfer to a word processor 
• Integrated Mini-CAD system for additional annotation of graphics
