Abstract

On September 2nd, 2022, an intense and prolonged rainfall event caused severe flooding, landslides, debris flows, and groundwater rise, resulting in substantial damage, particularly in the northern slopes of Sredna Gora Mountain in Central Bulgaria. Various methodologies, including field analysis, remote sensing, and GIS tools, were employed to analyze the disaster’s causes and field conditions. Active sediment sources, deposition patterns, and mapping techniques were used to document the disaster’s impact. The results showed that the disaster resulted from the formation of numerous landslides, and rapid hydrological response led to riverine flooding, high-speed flows, and sediment deposition. An important contribution of this study is the generated landslide inventory map, that can be used for mountain road reconstruction and the planning of mitigation measures.
2022 年 9 月灾难对卡尔洛沃市卡拉韦洛沃、博格丹和斯拉蒂纳村地区的影响评估
2022 年 9 月 2 日,一场持续时间较长的强降雨引发了严重的洪水、山体滑坡、泥石流和地下水上升,造成了重大损失,尤其是在保加利亚中部 Sredna Gora 山的北坡。我们采用了各种方法,包括实地分析、遥感和地理信息系统工具,对灾害的原因和实地情况进行了分析。研究人员利用活性沉积物来源、沉积模式和绘图技术来记录灾害的影响。结果表明,灾害是由大量山体滑坡形成的,而快速的水文反应导致了河水泛滥、高速水流和沉积物沉积。本研究的一个重要贡献是生成了滑坡清查图,可用于山区道路重建和减灾措施规划。
