Description
Summary:The Latian Reservoir (70 Mm3) is located about 35 Km Northeast of Tehran and supplies drinking water to more than 2.5 million people in the greater Tehran metropolitan area. The main sources of water to the Latian Reservoir are the Lavarak River and the Jajrood River watershed which are becoming highly populated communities discharging their waste directly into surface waters. The results of a 3-years water quality monitoring show that this reservoir is in the eutrophic stage because of high levels of nitrogen and phosphorus concentration. Because of the phosphorus role in lake and reservoir eutrophication, in this paper several well-known models of phosphorus were compared and eventually Snodgrass-O’Melia phosphorus model was selected for long term phosphorus simulation in this reservoir. Decrease of phosphorus concentration in the Jajrood River is the most effective way for decreasing phosphorous concentration in the water body of reservoir.
