University of Tehran Journal of Environmental Studies 1025-8620 26 26 2000 12 21 Environmental Management of Siah-Rud River and Economic Analysis on Sewage Purification Environmental Management of Siah-Rud River and Economic Analysis on Sewage Purification 25636 FA Journal Article Considering the water scarcity in Iran and the importance of environmental protection, it is approperiate to investigate the \ environmental management of Siah-Rud river. It is a small river being utilized as discharge channel by factories located in the vicinity of the river. The physico-chemical characteristics of river water at 10 different sampling locations 'along with coefficient of aeration (K1, Kd) , and self purification of the river were determined. Using a linear computer programme , an optimization-model for the minimum treatment efficiency at each pollutant source, along with dissolved oxygen and BOD, in the course of river was developed Considering the water scarcity in Iran and the importance of environmental protection, it is approperiate to investigate the \ environmental management of Siah-Rud river.
