  4. Abstract:
  5. The Latian dam is located on the Jajrood River in the northeast of Tehran the capital of Iran. It is one of the most important water supply reservoirs in this city and supplies 30 percent of the total water demand of 11 million people in this city. This research measures phosphorus release from sediments of Latian Dam and the role of the tubifex in phosphorus release. Because of sediment composition variation, sediment sample were taken from two points in the Latian dam. The sediments were analyzed for total phosphorus, the form of phosphorus and release rate under different conditions of water column and the absence or present of tubifex. The results show that the amount of phosphorus are equal in the two points of the dam but the sediments that have clay in their texture have a greater phosphorus release rate than the sediments that have sand in their texture in anoxic periods. Furthermore in the Latian Reservoir the tubifex has been shown to contribute significantly to the phosphorus release. Copyright ASCE 2005
