| description | Hydraulic structures such as sluice gates are more sensible of driftwood that is transported by a river; all this debris, like a trunk, deadwood, and rootstocks, can be accumulated upstream hydraulic structures may cause many hydraulic troubles, so studded such as these phenomena more essential to prevent or reduce its effects on these structures. Many studies dealt with the impact of driftwood on scouring around piers and weirs and its hydraulics, but the studded dealt with sluice gate structures are few and still need deep studies. This study dealt with the sensitivity of driftwood blocking flow under a sluice gate. It found that a large gate opening and 50% of the maximum upstream head lead to a decreased probability of trapped index and an increasing likelihood of driftwood passage beneath the sluice gate, which causes scour if driftwood is blocked under a sluice gate, so this case must be avoided. The driftwood trap probability of rootstock is greater than the trunk, and accumulated driftwood causes an increasing upstream water depth by 15%. Increasing its volume increases trapping probability. |
