Title

Modeling Water Quality of Sefidroud River Using Qual2kw

Pages

  121-131

Abstract

 The objective of this research is to investigate the accuracy of Qual2kw software in Simulating the quality parameters of Sefidroud River at the bottom of the dam. For this purpose, sampling and conducting laboratory studies for 12 stations in the range of 110 km in two summer seasons (August) and autumn (November) in 1398 has been done. In this study, Qual2kw software to simulate the eight main parameters of water quality including water temperature, pH, electrical conductivity, total suspended solids, soluble oxygen, biochemical oxygen demand, total nitrogen and total phosphorus, for August and November 1398, respectively, measured and verified Is. The results showed that the highest and lowest accuracy of the model with average NRMSE values in two stages is equal to 3. 3 and 47. 5% for pH and total nitrogen parameters, respectively. The highest correlation values between the measured and simulated values for the parameters of total solids and electrical conductivity were 0. 97 and 0. 96, respectively, in the model calibration stage. The results of the present study indicate the appropriate capability of Qual2kw model to model Water quality parameters of Sefidroud River. The results of the present article indicate the appropriate accuracy of the Qual2kw model in order to simulate Water quality parameters in the Sefidrood River, which is in accordance with the results of Aryan, Nejad et al. (2015). It should be noted that the hydraulic properties of the flow affect the amount of dissolved oxygen in the Sefidrood River more than changes in the quality of other parameters.
