Abstract

In this paper, by using variance based methods, the Sensitivity Analysis of the two well recognized water quality indices, namely NSFWQI and IRWQISC, is presented in a comparative approach. The research was conducted by employing monthly sampling in thirteen stations on Pasikhan River during 2015. Sensitivity Analysis for the parametres of the two models on one hand led to recognizing the most important parameters for a better measurement and on the other hand helped evaluation of the correctness of the parametr weights used in the model developed in Iran. In seasonal analysis, BOD was determined as the most sensitive parameters for both indices. In spatial analysis, NSFWQI classified the river water quality as “ Good” and “ Bad” in upstream and downstream of Pasikhan River, respectively. Using Factor prioritization approach, it was found that DO was the most effective parameter in NSFWQI, for which applying the approach minimized the uncertainty of the model output. In IRWQISC, DO at U/S stations and BOD at D/S stations were the most influencing parameters on the model output variance, which emphasized the importance of the frequency and precision of sampling for these two parameters against the others. Another important achievement of the present research was revealing the inconsistency of the weights used in IRWQISC, with respect to the sensitivity of the parameters and their influence on the model output in Pasikhan River.
