Safe and uninterrupted road travel is crucial after storms so people can get medical care, power lines are cut off, and communities can begin to return to normal life.

Researchers from the Center for Sustainable Infrastructure and Disaster Response (RIDER) of the FAMU-FSU College of Engineering are exploring the best ways to predict where debris that kills roads will be most severe after tropical cyclones. Their latest work was published in International Journal of Disaster Risk Reduction.

“This study is especially relevant as hurricane season approaches because it reminds us that we need a variety of tools to respond appropriately to these storms,” said Eren Ozguven, director of the RIDER Center and senior author of the article. “This paper describes an important tool and applies it to the Florida Panhandle disasters.”

Researchers used satellite imagery to measure the amount of vegetation in Bay County, Florida, before and after two tropical storms and three hurricanes, including Hurricane Michael, a Category 5 storm that devastated the county in 2018. This gave them an estimate of how much vegetation debris caused these storms and where the debris was most severe. They were able to correlate measurements of debris with factors such as wind speed, initial amount of vegetation and road density.

The researchers found that garbage was heavier in suburban and urban areas, which have a high density of people and roads, compared to rural areas. Although vegetation is not the only type of debris caused by hurricanes, it is an important predictor of where roads will be blocked.

Researchers are looking to develop a tool that will give emergency management planners an assessment of storm wreckage, which likely allows officials to plan, for example, where to place trucks and collection areas before storms.

“The sooner you can remove garbage from the roadway, the better you will return to normal life after the hurricane,” said co-author Tarek Abichev, professor of civil and environmental construction at FAMU-FSU. techn.

Along with understanding where to deploy resources before a storm, officials can use satellite imagery after a hurricane to quickly and inexpensively get an idea of ​​post-storm damage before deploying rapid response services.

The work is part of RIDER’s efforts to use remote sensing technology to solve civil engineering problems.

“Engineering is a search for solutions despite obstacles, and hurricanes create all sorts of obstacles,” Abichev said. “Improving our ability to use remote sensing to prepare for and recover from storms will help us overcome these challenges.”
