Construction of 3D Rainfall Threshold Surface for Debris Flow Warning
Construction of 3D Rainfall Threshold Surface for Debris Flow Warning is a scholarly work, published in 2018 in ''International Journal of Engineering and Technology''. The main subjects of the publication include agricultural hydrology, debris flow, debris, landslide, environmental science, warning system, geology, retreat of glaciers since 1850, meteorology, and computer science. Rainfall-induced debris flow caused by climate change has recently become a threat to human life worldwide.Types of rainfall characteristics, namely, high rainfall intensity for a short duration, high accumulated rainfall for a long duration, and postseismic effects were investigated to build a 3D rainfall threshold surface for debris flow warning.Rainfall parameters including effective accumulated rainfall, intensity, and duration were investigated in the 3D analysis.The construction of a 3D rainfall threshold surface enhances knowledge on the rainfall characteristics that initiate debris flows.Rainfall monitoring in consideration of different rainfall characteristics can improve predictions of debris flow and thus facilitate the issue of timely warnings.
