Abstract (2. Language): 
Turbidity currents are gravity currents in which the difference of density or weight difference between two fluids is because of suspended sediments. Considering sedimentation of turbidity currents in dams’ reservoirs, hydrodynamic recognition of these currents will have great effect on increasing useful life of dams. So identifying hydrodynamic and characteristics of turbidity currents is very important in different fields. Using FLOW-3D and Fluent software velocity in the body of turbidity current has been modeled and compared to each other in this paper. The obtained results of numerical models of velocity profile in the body in inner regions (between bed toll maximum velocity) and in outer region (between the maximum velocities until the velocity gets almost zero) have relatively good compliance.
