One of the most important problems in determination of useful age length of dams, are form and time of filling of dams reservoirs, of river sedimentation in upstream. Mathematical models recently are used for simulation of the reservoir sedimentation rates and prediction useful life of the reservoir. These models are based on the analysis of equations governing sediment transportation, distribution, deposition, and scouring. In this study, mathematical modeling of erosion and deposition of sediments in Satarkhan dam, has been studied using GSTARS 3.0 model. GSTARS mathematical model using stream tubes concept, has an ability to account for the longitudinal and lateral distribution of sediment deposition in the rivers and dams. For hydraulic and sediment calibration of this mathematical model, stochastic and information of Satarkhan Dam and cross section topography between 1998 and 2009, have been used. Calibration results showed that Yang (1973) sediment transport equation had good agreement with field data.
