Abstract:

PROFILE is a mathematical soil chemistry model which has been computerized. The model calculates the steady-state chemistry down through a soil profile, layer by layer.
PROFILE needs good, real soil chemistry data as input. Profile allows to change parameters such as deposition rates and to assess the impact of such changes on environmentally important chemical parameters.
The PROFILE model has been developed by Dr. Harald Sverdrup, Dr. Per Warfvinge and Mattias Alveteg at Lund Institute of Technology in Sweden, with financial support from the Swedish Environmental Protection Board, SNV.

The Profile model is basically a steady-state version of the SAFE model. Profile does however include some features not included in SAFE. Profile also has a HyperCard user-interface (on Mac's). There is also a standalone version of the Mac user-interface, which is handy if you do not have HyperCard 2.1 or later. Profile 4.0 for Mac includes Mineralstack 2.0.
