Visiting the site of a natural disaster can be overwhelming, but it can also provide some important information about how to prevent so much damage when the next severe weather event inevitably rolls around. Michael w88 sports betting app, assistant professor in the Department of Geological Sciences and Engineering, recently travelled to Europe to understand how severe flooding this summer impacted geo-structures like dams, dykes and bridges, and how they can be built safer to prevent disaster again.
w88 sports betting app travelled to Europe as part of a Geotechnical Extreme Events Reconnaissance (GEER) Association team. GEER members mobilized to respond to heavy flooding events in Germany, the Netherlands and Belgium and visited the sites in August.
“The magnitude of the flooding was astounding – the high-water mark in some places was over six meters (about 20 feet). Houses were swept away and carried downstream, only leaving their foundations behind. Many bridges were either heavily damaged or completely destroyed,” w88 sports betting app. “The rainfall during this single event was on the order of what might be typical for the entire year in some of the flooded areas and was orders of magnitude greater than what was predicted,” he added.
Gardner was an academic member of the US-based team, which was led by Anne Lemnitzer of the w88 sports betting app of California, Irvine and Nina Stark of Virginia Tech. This team collaborated with local engineers and scientists from the study areas. Gardner’s efforts involved data collection via drone imagery, LiDAR scans and multispectral imaging.

“The data gathered during this reconnaissance and what we learn from it ultimately will help us design and upgrade infrastructure to better meet the demands imposed by extreme and changing weather events,” w88 sports betting app.
The most challenging part of this project, w88 sports betting app, was seeing the aftermath of the disaster and the destruction of peoples’ lives. “While it is a great opportunity to gather important perishable data and fascinating to see different aspects of how infrastructure performed, it is difficult to see peoples’ livelihoods ruined and their grief for lost loved ones.”
Another consideration of this research is how the places hit by the flooding will rebuild. “Beyond the highly visible destruction, most of the towns hit by these floods will essentially have to be rebuilt due to extensive water damage. Many of them have been around since 1400 or before, so rebuilding them to the same character will be difficult and expensive,” w88 sports betting app.
Speaking to the importance of pooling resources with local and international researchers, w88 sports betting app, “This joint effort results in a higher quality report and more data being collected in a deliberate fashion. Ultimately, all the data is made available online so that anyone can access it, which might not have been the case if GEER was not involved in the effort.” He added that working with local engineers and scientists allows the team to utilize their vast local knowledge which is, “essential to the success of the response.” The reconnaissance report will likely be published late this year and can be accessed at w88 sports betting app’s website. This is the second reconnaissance team w88 sports betting app has been a part of. He was on a team as a graduate student responding to the 2014 South Napa Earthquake.
