  • Summary: Record rainfall triggered devastating and deadly flooding in Western Europe between July 14-16th, 2021. The extreme weather event killed more than 230 people in Germany and Belgium and cost billions of dollars in damage. Reconnaissance studies within some of the most affected areas of all three countries, provided insight into geotechnical and geo-structural performance behavior of critical infrastructure elements, such as bridges and road networks. This report presents reconnaissance observations collected between August 9th - August 16th, 2021. The reconnaissance team used terrestrial LIDAR technology, Multispectral imaging, visual observations and cellular photography, as well as UAV imaging and structure for motion modeling to discern critical damage patterns of infrastructure networks and buildings, and to document important erosion and soil relocation patterns along the river courses.

The work of the GEER Association, in general, is based upon work supported in part by the National Science Foundation through the Geotechnical Engineering Program under Grant No. CMMI-1826118. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of the NSF. The GEER Association is made possible by the vision and support of the NSF Geotechnical Engineering Program Directors: Dr. Richard Fragaszy and the late Dr. Cliff Astill. GEER members also donate their time, talent, and resources to collect time-sensitive field observations of the effects of extreme events.
