STUDY OF THE SCOUR MODEL AROUND THE SLUICE GATE OF OPEN CHANNEL

This study aims to determine effects of variations in gate opening at constant discharge on scour depth and flow pattern of the bed of open channel using clay around the sluice gate. Each experiment used a constant discharge and starts from a flat bottom during an hour of flowing. The results of this study indicated that the gate opening affected the flow pattern of energy.. Flow Changes can be observed visually or based on the number Froude. In addition, the flow occurred in upstream and supercritical flow downstream is sub-critical flow. At the gate opening of 0.5 showed that scour pattern was the deepest compared to the gate openings of 1.0 and 1.5. Based on the observation that the greater the discharge the scour depth.
