Abstract

One of the most important issues in water supply for agriculture or drinking is sediment control.
Sedimentation in water conveyance channels reduces transmission efficiency. this study evaluated the
efficiency of settling basin of Kamandan intake that is located in the village of Aligoodarz in Lorestan
province. At first sample from water and sediment in inlet and outlet of settling basin in different
discharge and sediment concentration of particles was determined by laboratory tests. Then the
sediment trap efficiency of settling basins was calculated. Also the measured values of trap efficiency
are compared with efficiency values calculated by the mathematical models proposed by different
researchers. The results show that the sediment trap efficiency of Kamandan basin calculated by Garde
& Range model is closer to the value measured with the direct method. Therefore the Garde and
Range model can estimate the sediment trap efficiency of Kamandan basin better than other models.
