Abstract: Permeable frames have been widely applied in river and channel regulation since they serve the function of decelerating flow velocity and thus protecting bank and beaches from water erosion. Three-dimensional velocity meter (Vectrino) is used to measure the flow vector filed precisely near the newly-proposed twist double I-shaped permeable frames on varible slope flume. The study reveals that when new permeable frames are thrown on the bed, the velocity of near-bottom layer plummets (deceleration rate of 0.79 to 0.95), the surface velocity increases, the gradient of transition layer velocity increases, and the vertical velocity no longer obeys the logarithmic distribution; the largest vertical turbulence intensity appears near the top of the frames, turbulence intensity gradually strengthens after the water flows into the frames, and reaches the peak when flowing out of the frames. The peak location of turbulence intensity of the surface lies in the downstream when compared with that of bottom. The findings have certain reference values on the design and application of new permeable frame. © 2014 Taylor & Francis Group, London.
