In this paper, we use five different slopes and different kind of variables, as changing the shape, size and group spacing of the energy dissipation ladder model. After the ladder model is placed in the water channel of the open channel flow device, the relative position and height are marked on the side of the waterway to observe the water flow through the energy dissipation, and also analyzing the change of the water level after the ladder module changes with the height of the water level after the energy of the water flow is destroyed.
After the experiment, it is found that the effect of different step shapes on the water-flow characteristics of the canal flow. The steeper the slope, the placement of any shape of the energy-dissipation structure is close to no effect. This finding seems to show that the effect of energy dissipation isn't significant as placing the structure.
Because of the streams in Taiwan are short, the vapor is usually not easy to keep, and the sediment at the bottom is difficult to retain. Based on the conclusions of this test, it is possible to explore the revolutionary energy-dissipating structures to achieve the functions of energy dissipation, hydrophilicity and environmental protection.
