Abstract

Duckbill weir is one of the water level control structures in irrigation networks. If Sediments are transferred into the irrigation networks, they trapped in the upstream of weir and effect on the upstream water level. In this study, Submerged vanes are used for flushing the sediment to downstream in addition of gates. The Flow-3D Software has been also used for simulation of flow and Sediment pattern. The results showed that Submerged vanes create secondary flow which is so effective for flushing the sediment especially in value of head over side wall to the weir height more than 0. 33. The results of image processing showed that the maximum relatived error for simulation of Sediment pattern is 14. 4 percent.
