Abstract:

The Pattiro Irrigation Canal in Bone Regency has sedimentation problems, which cause a reduction in the discharge capacity of the cross-section of the channel and reduce the efficiency of water distribution to agricultural areas. This study aims to analyze the influence of flow speed on the distribution of sediment transportation, examine sediment characteristics, and compare the flow speed between the upstream and downstream parts of the primary channel of Pattiro Irrigation. The data obtained show that the sediment transport process occurs when the shear stress of the flow exceeds the critical shear stress of the sediment particles. The distribution of sediment along the channel shows variety, where fine-sized materials are more dominant upstream, while coarse-sized materials are more prevalent downstream. The pattern indicates that flow energy has an important role in the transport and deposition of sediments. Hydrodynamic analysis showed that the flow speed in the upstream part reached 0.882 m/s with an average depth of 1.08 m, while in the downstream, the speed decreased to 0.556 m/s with a depth of 1.30 m. The decrease in speed caused some of the sediment carried from upstream to experience sedimentation downstream.
