The use of fuzzy logic for the study of water pollution in the Thermaikos Gulf
H. Mpimpas, Jacques Ganoulis, Petros V. Anagnostopoulos · 1999
The fuzzy set theory is applied to define the imprecise parameters which are used in a water pollution model. The physico-chemical coefficients and the loads of pollution sources involved, are expressed in the form of triangular fuzzy numbers. A two-dimensional finite element algorithm based on the characteristic-Galerkin technique combined with fuzzy calculus is used for the solution of the advection-dispersion equation, for ten different water quality parameters. The model is applied for the study of distribution of pollutants in the Gulf of Thermaikos, located in Northern Greece.
