  • 摘要:Today, due to the usage of rivers for transferring urban and industrial wastewaters aswell as agricultural drainage water, they are exposed to different sources of pollution.Therefore, knowing the trend of qualitative changes of rivers is effective for controllingpollution sources. In this study, the water quality of Zayandehrood River wasinvestigated and for simulation of qualitative data, Qual2kw model was used. Theinformation used includes qualitative information of the river water and hydrometric,meteorological and contaminants information. The investigated parameters were BOD,DO, and nitrate which were taken from 12 stations. Simulation of qualitative data byQual2kw model for BOD and DO parameters suggests that there is a suitable matchbetween the measured and simulated data, but simulation for nitrate parameter was notperformed well. The results of model indicated that due to withdrawal of water foragricultural uses, the river water’s flow rate was very low at terminal stations.Furthermore, dissolved oxygen concentration in these stations was very low, while thechemical oxygen demand concentration was very high due to entry of industrial andhuman wastewater. For this reason, the river is no longer able to receive organic loadand does not have self-purification capability.
