| Abstract: | The velocity distributions at the spillway buckets with three kinds of roughness and two radius are measured by using LDV. The results show that flow pattern, wall roughness and wall curvature may significantly effect the boundary layer hydraulic characteristics. |

| Keywords: | transitional region turbulent flow boundary layer roughness curvature |
