New approach for water quality analysis and modeling

Abstract

Watercourses present a special case of water reservoirs. Regardless to the method of their investigation, there is still a search for the convenient method for processing of collected measurements of water quality parameters. Research direction was defined by the EU directive framework for aquatic bodies. Taking into consideration the existing methods for water quality analysis, this paper presents a proposal of a new method for analysis and modeling the aquatic body behavior. The measurements conducted at five stations on the river Ibar in the period from 2007 to 2012 are used as a basis. The basic method is based on multivariable analysis of unevenly time spaced measuring data. The basis was the correlation analysis that defined dependent parameters for determination the SWQI indices. Analyses have shown that the obtained results can be used for establishing an integral monitoring the water quality of aquatic system of the river Ibar. Also, they pointed out the possible directions for measurement and analysis upgrading.
