The current gravitational non-transferable dams used to cause more damage by flooding over completely blocked areas when landslide
was caused or causing environmental problems such as water pollution when the precipitation was low. In this research, we proposed
a new type of debris barriers that overcome for problems of the existing debris barrier but also improved the efficiency of decreasing
debris flow. However, pre-researching on the protection effects of debris barrier due to the shape and placement of the transferable dams
is inadequate. Unlike linear typed debris barrier, we produce curved typed debris barrier and ladle typed debris barrier which can capture
debris flow effectively though get out water as introduced a curve. Then we set the simulator and compared debris flow and thickness of
deposition to change to 15° and 20° the slope of the simulator. In addition, the installation angle of the debris barriers model was changed
to 30°, 60° and 90°, and we also compared effect of reducing the leakage of debris flow each new type of debris barriers. As a result,
linear shaped debris barrier, curved typed debris barrier, and ladle typed debris barrier all contributed to the decreasing debris flow. In
particular, the flow rate and prevent very efficient bottom deposition.
