摘要

River water quality assessment, affected by pollution load, and river regime changes in various climate conditions, is an implementation thatsimplifies water resources management, and justifies terms for increases or decreases in human activities. The current paper aims to offer awater quality model of a river considering parametric, hydrologic, and pollution load uncertainty by using uncertainty indexes like Plevel, ARIL,and NUE. These indexes were used to analyze the influences of the model’s parameters and the river’s regime alternations on the results. AQual2K model, calibrated with PSO algorithm, is presented and connected to GLUE algorithm to assess the model’s uncertainties like effectiveinput parameters on the modeled variations, headwater flow, and input pollutions. Zarjoob River, in the north of Iran, was chosen as thecase study. The results illustrate that the interaction among parameters, hydrologic and pollutant discharge data should be considered inriver water quality simulation. The presented methodology can analyze the influences of parametric uncertainty, parametric and hydrologicuncertainty, and pollution input load uncertainty according to any quantity of observations and the modeled results of any river.
