PREDICTION OF THE HYDROCHEMICAL REGIME OF SURFACE WATER USING SIMULATION MATHEMATICAL MODELLING

Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2012, Vol 453, Issue 453

Abstract

Mathematical simulation models of the hydrochemical regime of Velykyi Lyubin pond (Vereshchytsya River basin) and the pond of the Pidhaytsi town (Koropets River basin) have been constructed to clarify the possibilities of using such models in the practice of managing the quality of water resources in small rivers. To evaluate the ecological state of the Vereshchytsya and Koropets river basins – left tributaries of the Dniester – the expedition method was applied, i.e. collecting information on natural conditions and the content of nitrogen compounds (determined directly on-site) as well as Cl[sup]–[/sup] and SO[sub]4[/sub][sup]2–[/sup] ions in water. Information processing was performed by mathematical modelling of the hydrochemical regime of surface waters – calculation models to study the changes in the concentration of biogenic substances and chloride, and sulphate ions in the ponds have been developed. The simulation mathematical models of the hydrochemical regime of surface waters of the ponds were developed for different seasons by a direct construction of the chamber model based on the spatial averaging of the processes and compilation of balance equations. Mathematical models of the change in content of biogenic substances and sulphate, and chloride ions testify to partial purification of waters from pollutants, which is facilitated by the processes taking place within them (sedimentation, sorption–adsorption processes, dissolution).
