I have gathered water quality and discharge(head-flow) data in 9 points of Sefidroud river in IRAN.after water quality and quantity simulation,the amount of water quality and discharge in all reaches are not equal with the observed data. How can I enter this data to WEAP so that in every reach the water quality and discharge of Sefidroud river become equal with observed data. I have the same problem in linking qual2k and weap. I dont have exact amount of discharge into Sefidroud river by other resources and demand sites.
