I downloaded AquaSim demo version and some of tutorials as it is a recommended and used modeling package for our M. Sc course. The
AQUASIM has been designed to provide a more universal identification and simulation tool for a class of aquatic systems important in the
environmental sciences. An additional important program design criterion was user-friendliness, which was achieved not only by providing a graphical
user interface, but also by utilizing a communication "language" familiar to environmental scientists. AQUASIM is extremely exible in allowing the user
to specify transformation processes, and, in addition to perform simulations for the user-specied model, it provides elementary methods for parameter
identiability analysis, for parameter estimation and for uncertainty analysis.
AQUASIM was developed in the years 1991-1994 in the Computer and Systems Sciences department of the Swiss Federal Institute for Environmental Science
and Technology (EAWAG), CH-8600 Dubendorf, Switzerland, and it is maintained and extended since then. The program was designed mainly for internal use in research and
teaching, but is also available to the public.
