Objective The mountainous area in Western Sichuan is located in the transitional zone between the Qinghai-Tibet Plateau and the Sichuan Basin. With active geological structures, debris flow disasters occur frequently, which have already caused significant casualties and property losses. Taking a debris flow in a certain area of the mountainous region in Western Sichuan as an example, this study aims to investigate the development characteristics of a debris flow in this area and propose measures for debris flow control. Thus, it can achieve the goal of protecting the lives and property of residents in the debris flow hazard area, and it is expected to provide a reference for similar debris flow control projects. Methods Methods such as collecting geological data of the study area, conducting on-site geological surveys, and performing mechanical calculations were adopted. Results For the studied debris flow, the likelihood and scale of its occurrence will be greater under the influence of heavy rainstorms and long-term rainfall. Corresponding control measures were proposed according to the characteristics of this debris flow. Conclusion In the face of the menacing and extremely destructive debris flow disasters, we must take a two-pronged approach. On the one hand, we should adopt effective control measures to fundamentally reduce the possibility and harm degree of debris flow occurrence. On the other hand, we should establish a complete monitoring system to achieve real-time monitoring and accurate early warning of debris flow disasters.
