| Abstract | ||
| A common problems faced by the side intake channels are sedimentation and sediment entry. These cause problems as limiting the flow ability in irrigation channels, and threatening to waterway block when the water level is low. This laboratory study was conducted to find out the effect of using one-row immersed vans in the main channel to control the sediments amount of entering the intake channel at an angle with two sand concentrations at granular diameter rate ( = 0.5mm). The first concentration flow rate was (1.8 ) And the second (2.22 ). The results showed that the use of a single row of submerged vans reduces the sediment amount that entered the intake channel by (35-65)% of the total sediments that were fed by the feeder channel for both concentrations. This indicates that use of submerged vans has a positive role in entry process and sediment transfer to branched channels. | ||
