Abstract :

       The transfer and sedimentation in storage dams reduce the volume and damage the life of water reservoirs. Due to the importance of water, its storage, and the cost time of constructing reservoirs, especially the scarcity of construncting sites for them, a lot of attentions should be given to the sedimentation of dam reservoirs. It requires the estimate of thew sedimentation and its management. Since all suggested techniques to estimate the sedimentation need field operations, time. And hight costs, this paper aims to comine the GSTARS2,1 mathematical model and the ILWIS software to suggest a proper method to estimate the sedimentation, and also to establish a proper date bank in the reservoirs. Miynab dam has been used to study and analyize dare. The resulte Show that we can use this method to estimate the sedimentation of dam reservoirs.
