The main drive for the present study is to investigate experimentally the energy dissipation through triangular screens. Recent experimental studies have shown that screens placed in vertical and inclined configurations below small hydraulic structures may dissipate more energy than a hydraulic jump formed in conventional stilling basins. In the present study a series of laboratory experiments were performed in order to determine the effect of triangular screens on the energy dissipation. The location of the screen from the hydraulic structure, upstream flow depth, the thickness of the screens, and the Froude number of the upstream flow are the major parameters in the laboratory experiments. Froude number of the upstream flow covered a range of 7.5 to 25.5. The results of the experiments show that triangular screens, like vertical and inclined screens, perform also very efficiently in reducing the high kinetic energy of the flowing water and that they reduce the energy at a higher rate when compared to a classical hydraulic-jump performance for the same Froude number. However, triangular screens have no superiority over the vertically placed screens or inclined screens studied previously.
