Also several rivers are originated from them; hence they have applied effect on life of habitants of seaports and coastal towns, also they help to human beings in obviating needs such as fisheries and watery transportation. The studies of water and fluid sciences have significant importance. The Karun river which is the biggest one in Iran passes from Khuzestan province through towns in its pathway. When Karun River comes to Shushtar basin, reaches to a regulative dam, and there is a secondary branch namely Gar-Gar which originated of it and is a artificial watery basin. In this paper parameters of deby sediments and speed of dominated flows in Shushtar basin were determined and flows of Karun River, Shushtar basin are modeled.
