Gates and orifices were significant common structures used in controlling and adjusting the flow in water system channels. Installing of an orifice with sluice gates, increase the flow discharge with minimizing the horizontal jets under gate that was attributed with higher bed flow velocity and larger scour geometry downstream these gates. An experimental study was conducted to examine the flow pattern and the bed configurations downstream sluice gates with an orifice. In this research, a circular orifice employed with sluice gates as a means of energy dissipation downstream the gates, was explored. Forty-five runs were completed under 3 discharges, 3 upstream water heads, and 7 tail gate water depths. Five models for sluice gate with orifice were utilized. A series of regime plots were created to help designing the sluice gate with orifice as heading up and flow distributions structures. The outcomes illustrated that combining of an orifice with sluice gates productively scattered the jump energy and diminished the downstream local scour compared to the conventional sluice gate. Additionally, existed equations used to predict the jump length downstream sluice gate were applicable in case of sluice gate with orifice provided similar flow conditions were achieved. The optimum ratio of orifice and under gate areas was also introduced.
