Abstract

The applicability of reliability analysis in numerical modelling of the quality of watercourses is studied. The QUAL2E-UNCAS Model is used to analyze the water quality in the upper reaches of the Sava River, in the territory of Croatia. The Monte Carlo simulation is used to analyse reliability of input parameters in form of coefficients relating to the organic matter disintegration and oxygen content in water. The analysis results are presented through basic properties of the probability density function for relevant output parameters on selected sites.
