"This is going to transform natural hazards reconnaissance research by making a collection of state-of-the-art equipment available to a wide community of researchers from across the country."
During a four-day intensive training at UW in July, researchers from across the country learn how to operate the Z-Boat 1800.
NSF-funded center gathers disaster related data to reduce risk
It may look like a toy boat, but the bright yellow Z-Boat 1800 has an important mission: capturing underwater topography for damage assessment following natural disasters. The small boat is one of more than 300 pieces of data-gathering equipment now available to researchers throughout the world.
To develop more resilient communities, the Natural Hazards Reconnaissance Experimental Facility officially launched in September to enable the collection, assessment and archiving of high-quality perishable data in the aftermath of disasters. Funded by a five-year $4.1 million Natural Hazards Engineering Research Infrastructure (NHERI) grant from the National Science Foundation, the center is the first of its kind in the world.
“This is going to transform natural hazards reconnaissance research by making a collection of state-of-the-art equipment available to a wide community of researchers from across the country,” said CEE professor Jeff Berman.
Headquartered in Civil & Environmental Engineering, the center is led by principal investigator and professor Joe Wartman, working in collaboration with Berman and chair and professor Laura Lowes. The interdisciplinary team includes research scientist Scott Miles from Human Centered Design and Engineering, professor Ann Bostrom from the Evans School of Public Policy and Governance, software development from Applied Physics Laboratory and researchers from the University of Florida, Oregon State University and Virginia Tech.
The new center launches during a time when natural disaster related losses continue to escalate. In the past 30 years, more than 2.5 million people and $4 trillion has been lost in natural disasters, according to the World Bank. In 2017, natural hazards resulted in $330 billion in global losses, a jump from $200 billion in 2014.
Transforming data collection
Working with existing organizations, including NSF-funded Geotechnical Extreme Events Reconnaissance Association, center staff equip researchers with tools and equipment for gathering data. Reconnaissance teams typically arrive on site within 1-2 weeks, to avoid interfering with immediate rescue response.
“Data on infrastructure response is perishable, it goes away very quickly,” said Jake Dafni, site operations manager for the center. “There is usually a big push to clean up the area and help affected communities get back to a semblance of normalcy, so the data disappears fast.”
Visiting researchers learn how to operate the BLK360, a lightweight, highly accurate close range laser scanner used to capture 3D point cloud and imagery data.
Collecting high quality data about damage and other impacts caused by natural hazards allows researchers to gain insight that helps inform the development of more resilient communities. From updated building codes to informing coastal development planning, the data is used by researchers to reduce impacts from natural hazards.
“One of the driving reasons to collect data is to validate models and design methods,” Berman said. “The better, higher resolution the data, the better the modeling methods will be.”
However, current post-disaster data gathering procedures suffer from a lack of state-of-the-art equipment and uniformity in collection means and methods, which can affect the quality of the data gathered. Without standardized procedures for sharing results, information is often tucked into drawers or saved on researchers’ hard drives.
“It’s not good data and it’s not being shared,” Dafni said. “We are offering equipment that can capture much better data and not just for the person who is collecting it.”
To enable systematic data collection, a custom mobile application is under development, called the “RApp,” to guide researchers through standardized data collection methods. The app will also manage various types of data gathered, from handwritten notes to photographs to 3D point clouds, automatically uploading everything to a data repository called Design-Safe, which is accessible to the larger research community.
The center also offers data visualization and assessment by allowing researchers to “see” the disaster scene in three dimensions, so they can continue their investigation of the damaged infrastructure well after cleanup has occurred. The data visualization “CAVE” utilizes technology pioneered by partner Oregon State University.
Well-equipped with 300 tools
During the past two years, the center has procured more than 300 pieces of equipment worth an estimated $1.2 million. In addition to surveying tools and seismic instruments for monitoring aftershocks, the equipment portfolio includes a suite of equipment to collect high-resolution 3D information on the state of structures, slopes and coastlines. The equipment includes laser scanners (lidar) and a fleet of drones outfitted with ultra-high resolution cameras— one of which is even equipped with lidar.
More specialized and experimental equipment includes the Z-Boat 1800, which uses sound waves to capture underwater topography information about the depth of lake or ocean floors for damage assessment; social science equipment such as EEG headsets to measure electrical brainwave activity and assess stress levels related to disasters; and an Applied StreetView camera to capture 360 degree imagery from a moving vehicle, enabling large-scale damage surveys.
To begin building a base of researchers familiar with operating the equipment, a four-day intensive training was held at UW in July. While training is not mandatory for users, they are welcome to visit the center for a refresher or quick training session prior to reconnaissance deployment.
Getting the equipment in the hands of researchers across the country has proven to be the biggest logistical hurdle. In addition to deployment destinations throughout the world, the equipment comes in various shapes and sizes. The small boat, for example, must currently be shipped in a crate.
“We’ve gone through several scenarios,” Berman said. “Sometimes the equipment will go to the researcher’s university and they will fly or drive with it to the field work site. Other times, we will ship it directly to the field site.”
Since the center became operational in September, data gathering equipment has been deployed to several disaster sites around the world:
Using equipment from the new center, researchers obtained video of a dam washout.
Hurricane Florence in North Carolina, U.S.
Following catastrophic damage from freshwater flooding in September 2018, two reconnaissance teams were deployed to North Carolina to assess damage from the hurricane using the Applied StreetView camera to capture continuous 360 degree imagery, close range laser scanners, drones and GPS units to build 3D models, and a thermal camera to assess water damage.
Earthquake in Chitose, Japan
Following a magnitude 6.6 earthquake, alumnus Alex Grant (Ph.D. ‘17), who works for the United States Geological Survey, was part of a two-person reconnaissance team that used close and long range laser scanners to gather data about landslides and liquefaction features.
