The expert system DELAQUA (Deep Expert system LAke water QUAlity) combines AI and simulation methods to support decision making in water quality control of lakes and reservoirs. It contains a knowledge base (PROLOG 2), a data base (dBASE III+) and a simulation system (FORTRAN 77) by which the following decision aids can be made available:

  1. derivation of recommendations for operational control of undesired impacts on raw water quality by algal blooms or pathogen germs

  2. classification of raw water quality by means of legal standards

  3. drawing of analogy conclusions by the use of measured and simulated water quality data of reference waters

  4. predictions of raw water quality under changing control strategies and environmental conditions of lakes and reservoirs.

The expert system was implemented on an IBM-PC with MS.DOS operating system.
