Understanding the trend of changes and also prediction of Karoon water quality now and in the future through the development programs for urban, agriculture, and industry sectors enable the policy-maker to predict the future problems and plan accordingly. So, the study of Karoon river training program has been undertaken to investigate the water quality condition. For distinguishing the problems which are emerageing from poor operation of reservoirs in the past as could be seen from the prior investigation, a simulation model is needed. Also considering the importance of new data of the water quality, one year of data is collected and new status have been proposed. Qual2E simulation program has been calibrated and used. The results show the poor water quality of the river at present and in the future if the waste waters are not treated property.
