    Investigation and analysis of the "2023.8.11" Haogou mudflow disaster in Chang'an District of Xi'an City of Shaanxi Province

    • 摘要: 2023年8月11日,陕西西安长安区滦镇街道喂子坪村鸡窝子组蒿沟发生泥石流灾害,造成25人死亡,2人失联。为调查分析灾害机理,查清致灾原因,通过实地查勘灾害现场和蒿沟沟道,采用无人机第一时间航拍获取灾后蒿沟泥石流沟道和流域三维影像数据,通过雨水情计算、泥石流形成条件分析、势能计算、机理和过程分析、堆积体体积与沟道块石储量对比分析,经综合研判,本次灾害事件是降雨诱发的典型泥石流灾害,人员伤亡由泥石流造成。
