ASM (Aquifer Simulation Model) is a horizontally or vertically, two-dimensional groundwater flow and transport model. The program offers the following options:

The solution of the flow equation uses a finite difference method. The system equations can alternatively be solved with the method of preconditioned conjugate gradients (PCG) or the IADI-method (Iterative alternative direction implicit procedure).
Pathlines and isochrones are computed by Euler-integration. The interpolation of the velocity alternatively uses the methods by Prickett or Pollock. Solute transport simulation uses random walk method based on Fokker-Planck theory. Pathline and isochrone calculations as well as transport simulation are possible for steady state flow fields only.
