COMPLEMENTARY APPROACH FOR NUMERICAL MODELLING OF PHYSICOCHEMICAL PARAMETERS OF THE PRUT RIVER AQUATIC SYSTEM

摘要

In this article we present a complementary approach to modelling physicochemical state parameters of the aquatic system. Thus, after eight years data collection of chemical and physicochemical parameters at one sampling station situated on Prut River we tried to develop a multi-linear statistical model based on ANOVA analysis. The analysed parameters are measured for classification of surface water and in the second stage have been used to develop a dynamic model. This dynamic model is a more evolved one than the statistical model, and describes how the analysed parameters provide information regarding the way of correlation between of them. By comparing these two models it can be appreciated the dynamic model refinement in natural connections between physicochemical parameters of natural ecosystems can be appropriated. This fact is the novelty of this paper.
