Research on debris flow risk in Xiabi Temple based on hydrodynamic analysis
Debris flow is a highly destructive geological disaster that poses a significant threat to the ecological environment and residents' lives. It is crucial to analyze and study the risk of debris flow in order to reduce the damage caused by it. Based on the survey and investigation of the debris flow gully in Xiabei Temple,a hydrodynamic model is established,taking into account factors such as rainfall,inflow,terrain,vegetation coverage,and building distribution in the area,to quantitatively study the risk area of debris flow disasters on an engineering scale. The results show that the model calculates and analyzes the impact areas of debris flow during high water periods and under P=5％,P=2％,and P=1％ conditions,which are 0. 80 km2,2. 97 km2,and 4. 43 km2,respectively. The model can dynamically output the affected areas under different rainfall intensities,which can be used for flood warning in mountainous areas. It provides model methods and technical support for hydrodynamic response under comprehensive measures such as debris flow risk assessment,prediction,and water conservancy regulation.
