Debris flow river blocking judgment method and system
The invention relates to the technical field of debris flow prevention and control engineering, and discloses a debris flow river blocking judgment method and system, and the method comprises the steps: firstly monitoring and recording target debris flow incoming flow characteristics and river motion characteristic data, then building a dragging effect numerical model, and judging whether a dragging variable is within a first threshold range or not, so as to preliminarily evaluate the river blocking risk. And if the risk is high, further establishing a hydrodynamics and debris flow deposition model, simulating a motion trail and a deposition process, and calculating a transverse deposition length and an average deposition height. According to the method, the debris flow river blocking risk is finally judged by comparing the parameters with the corresponding threshold ranges. The method has the advantages that debris flow motion characteristics and river channel characteristics are comprehensively considered, the judgment accuracy is improved, and an important basis is provided for disaster prevention and reduction. Meanwhile, the model is suitable for different environments and conditions, and the application range is widened.
本发明涉及泥石流防治工程技术领域，公开了一种泥石流堵江判定方法及系统，该方法首先监测并记录目标泥石流来流特性及河道运动特征数据，接着建立拖曳作用数值模型，判断拖拽变量是否在第一阈值范围内，以初步评估堵江风险。若风险较高，则进一步建立流体动力学和泥石流淤积模型，模拟运动轨迹及淤积过程，并计算横向淤积长度和平均淤积高度。本发明通过对比这些参数与相应阈值范围，最终判定泥石流堵江风险。其优点在于综合考虑了泥石流运动特性和河道特征，提高了判定准确性，为防灾减灾提供了重要依据。同时，模型适用于不同环境和条件，拓宽了应用范围。
