2021年7月14日至16日，创纪录的降雨和随后的洪水导致德国和比利时200多人死亡，数十亿美元的损失。美国国家科学基金会赞助的岩土极端事件侦察（GEER）协会侦察使命是由作者进行调查的影响，洪水在德国，比利时和荷兰。为期两周的使命为各种地质结构的性能提供了洞察力，如建筑基础，道路和桥梁。本文总结了美国GEER团队与许多当地欧洲同事合作进行的观察。提出的主要意见包括桥梁案例研究，冲刷和侵蚀对不同结构的影响，以及土壤-结构相互作用。还介绍了用于通知侦察使命的数据以及所使用的数据收集技术，包括地面激光雷达、运动中的无人机结构（SfM）和多光谱图像。
Between July 14–16th, 2021, record rainfall and subsequent flooding resulted in the deaths of over 200 people and billions of dollars-worth of damage in Germany and Belgium. An NSF sponsored Geotechnical Extreme Events Reconnaissance (GEER) Association reconnaissance mission was undertaken by the authors to investigate the effects of flooding in Germany, Belgium, and the Netherlands. The two-week-long mission provided insight to the performance of various geostructures such as building foundations, roads, and bridges. This paper provides a summary of observations made by the US-based GEER team in collaboration with many local European colleagues. Key observations presented include a bridge case study, the impact of scour and erosion on different structures, and soil-structure interactions. A review of the data used to inform the reconnaissance mission as well as the data collection technologies used, including terrestrial LiDAR, UAV-Structure from Motion (SfM), and multispectral imagery, is also presented.
