Abstract

The global research community is concerned about the potential impact of Lake Outburst Floods (LOFs) worldwide due to glacier retreat and permafrost melting as a consequence of global climate change. These conditions have led to the formation of new potentially dangerous lakes. Extreme climatic conditions, high topography, and active tectonics highlight the vulnerability of the Andean region. Additionally, the region is exposed to increasing urbanization pressures in mountainous areas. This review presents an updated inventory of LOF events in the Argentinean Andes (31–51° S) as a complete catalog is currently lacking. The main characteristics and hydrodynamic parameters were compiled from the collected historical LOFs, while missing data were estimated in this study. These findings provide insight into the dynamics and outreach of this type of threatening phenomena in the Andean region. Possible triggering mechanisms were investigated to better understand the main causes of LOFs in the Andes. This understanding is crucial for the development of effective prevention and mitigation measures against regional lake-related hazards.

与湖泊有关的灾害：了解阿根廷安第斯山脉历史上冰川和滑坡湖泊溃决洪水的综述

由于全球气候变化导致冰川退缩和永久冻土融化，全球研究界都在关注全球湖泊溃决洪水（LOF）的潜在影响。这些情况导致了新的潜在危险湖泊的形成。极端的气候条件、高地形和活跃的构造凸显了安第斯地区的脆弱性。此外，该地区的山区还面临着越来越大的城市化压力。本综述介绍了阿根廷安第斯山脉（南纬 31-51 度）LOF 事件的最新清单，因为目前缺乏完整的目录。主要特征和水动力参数是根据收集到的历史 LOF 事件编制的，而缺失的数据则在本研究中进行了估算。这些发现有助于深入了解安第斯地区这类威胁性现象的动态和外延。对可能的触发机制进行了调查，以更好地了解安第斯山区发生低纬度风暴的主要原因。这种认识对于制定有效的预防和减轻区域湖泊灾害的措施至关重要。

期刊介绍： The realization that a historical perspective is often useful, if not essential, to the understanding of most limnological processes has resulted in the recent surge of interest in paleolimnology. The main aim of the Journal of Paleolimnology is the provision of a vehicle for the rapid dissemination of original scientific work dealing with the reconstruction of lake histories. Although the majority of papers deal with lakes, paleoenvironmental studies of river, wetland, peatland and estuary systems are also eligible for publication. The Journal of Paleolimnology, like the subject itself, is multidisciplinary in nature, and papers are published that are concerned with all aspects (e.g. biological, chemical, physical, geological, etc.) of the reconstruction and interpretation of lake histories. Both applied and more theoretical papers are equally encouraged. The Journal of Paleolimnology will continue to be a major repository for papers dealing with climatic change, as well as other pressing topics, such as global environmental change, lake acidification, eutrophication, long-term monitoring, and other aspects of lake ontogeny. Taxonomic and methodological papers are also acceptable provided they are of relatively broad interest. New equipment designs are frequently featured. In addition to original data and ideas, the Journal of Paleolimnology also publishes review articles, commentaries and program announcements. A relevant Book Review Section is also featured.
