Multi-criterion water quality analysis of the Danube River in Serbia: A visualisation approach
Abstract
River quality analysis is an important activity which, in Serbia, has been performed using
the Serbian Water Quality Index (SWQI). This is a measure based on a weighted aggregation
of 10 water quality parameters. In this work, alternative methods drawing on visualisation
approaches used in multi-criterion decision analysis are applied to the problem of evaluating river quality in the Danube. Two methods are considered: one which constructs a
graph using the dominance relation combined with a further multi-criterion ranking
method, average rank, and the other in which the dimensionality of the data is reduced
using PCA for visualisation. Results for data collected in 2010 are analysed and compared
with the corresponding SWQI values for the river in that year, and we find that by
employing these methods it is possible to reveal more information within the data than is
possible by using SWQI alone.
