Abstract

A rainfall-induced debris flow occurred on 30 September 2022 closing the A87 trunk (strategic) road on the Isle of Skye for around two hours. Ground-based and aerial drone inspections were used to describe the event and a comprehensive rainfall analysis undertaken. It is concluded that the event was triggered by overland water flow from the slopes above the source zone as a result of high rainfall. The resulting translational slide transitioned into a debris flow that reached a pre-existing channel where entrained superficial deposits were deposited, adding to pre-existing levee structures before reaching the road. The rainfall that led to the debris flow was high intensity-low duration; the rainfall analysis encompasses annual, monthly, daily, hourly and 15-minute data, each aiding understanding of the climate of the area and/or the event rainfall. Comparison is made with a rainfall event the following month which was of a greater magnitude but of longer duration and lower intensity. The hazard at this location is a concern but the risk is emphasised by the proximity of the road to the steep slopes above and the lack of a viable detour. Thematic collection: This article is part of the Geo-resilience and infrastructure collection available at: https://www.lyellcollection.org/topic/collections/geo-resilience-and-infrastructure

A87 战略公路 Luib 处的泥石流：苏格兰斯凯岛

2022 年 9 月 30 日，一场降雨引发的泥石流造成斯凯岛 A87 干线（战略）公路关闭约两小时。我们利用地面和无人机空中勘察对事件进行了描述，并进行了全面的降雨分析。结论是，由于降雨量大，源区上方斜坡的陆上水流引发了此次事件。由此产生的平移滑坡过渡为泥石流，泥石流到达预先存在的河道，夹带的表层沉积物沉积在河道中，在到达道路之前增加了预先存在的堤坝结构。导致泥石流的降雨强度高、持续时间短；降雨分析包括年、月、日、小时和 15 分钟数据，每种数据都有助于了解该地区的气候和/或事件降雨情况。与下一个月的降雨事件进行了比较，该降雨事件的降雨量更大，但持续时间更长，强度更低。该地点的危险令人担忧，但由于道路靠近上方的陡峭斜坡，且缺乏可行的绕行路线，因此风险更加突出。专题集锦：本文是地质灾害与基础设施专题集的一部分，可从以下网址获取： https://www.lyellcollection.org/topic/collections/geo-resilience-and-infrastructure

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
