Analysis of swqi index of the river Ibar (Serbia)

Abstract

The characterization of water quality is based on data from five hydrological measuring stations along the Ibar River flow through Serbia for the period from 2007 to 2013.The paper presents a new approach to surface water quality research using SWQI index assessment (Serbian Water Quality Index). The SWQI indicator is based on the original WQI (Water Quality Index) method. The environmental indicator for the area of waters SWQI shows that the calculated values of the index number are in the range of 77 to 82, the water quality of the Ibar River, which corresponds to the descriptive indicator of "good water" i.e. II class of watercourse rating. A significant correlation exists between the values of the BPK5 and SWQI parameters.
