Vekua Institute of Applied Mathematics, Tbilisi State University, Tbilisi, Georgia 3 Department of Informatics of the Muskhelishvili Institute of Computational Mathematics, Georgian Technical University, Tbilisi, Georgia Abstract Imitation models for computing the environmental water pollution level de- pending on the intensity of pollution sources created by the author over the years are presented. For this purpose, an additive model of a non-stationary random process is considered. For the modeling of its components, models that consider only dilution and self-purification processes are proposed for waste water and three-dimensional turbulent diffusion equations for river waters, and multidimensional Gaussian Markov series are proposed for mod- eling the random component. The purpose, the capabilities and the peculiari- ties of such imitation models are discussed taking into account the peculiari- ties of the water objects. The modular principle of creating imitation models is proposed to facilitate their development and use.

Introduction The formation of the quality of natural waters is a very complex process. Among the numerous factors that determine their condition, industrial waste water should be singled out. In order to protect natural waters from pollution by in- dustrial effluents, expensive treatment facilities and wastewater control systems are being built. The efficiency of investments depends on the optimality of the How to cite this paper: Kachiashvili, K.J. and Kvaratskhelia, V.V.
