Abstract: 

Dez dam is very important due to water supply, regulating power frequency and flood control. Because of high sedimentation in front of dam structure, there is a risk that fine sediments enter the power intake and endanger the efficiency of turbine runners. In this regards, use of turbidity currents potentials is one of effective solutions. In this study, the results of three stages of field measurements including current velocity and sediment concentrations in various stations was analyzed and sediment volume entering into reservoir, due to turbidity currents was calculated. The results showed that only in one flood event on April 2003 (with flow discharge of 2600 cms), nearly 1.1 Mm3 sediment has been deposited in front of dam structure. Maximum thickness of turbidity current has been evaluated to be 25 m in this flood event. Also, it is revealed that in addition to flood discharge magnitude, the time of flooding is also very important for calculation of sediment volume resulting from turbidity currents.
