NICHE: South Florida's new home for extreme storm research

Resilience Science gets a Makeover 

As stronger storms, rising costs and growing coastal populations reshape the nation’s understanding of risk, FIU is leading the most ambitious leap forward in resilience science in a generation.

 With a U.S. shoreline population of approximately 131 million people (39% of the population), natural hazards now inflict more than $100 billion in damages annually – impacting homes, economies, infrastructure and national security. Amid these realities, FIU is spearheading the creation of the National Full-Scale Testing Infrastructure for Community Hardening in Extreme Wind, Surge, and Wave Events – or NICHE – a groundbreaking facility that, when built, will redefine how researchers study the forces behind extreme events. With its design supported by funding from the National Science Foundation, NICHE would be the world’s largest testbed for exploring the combined effects of extreme wind, storm surge and waves on full-scale structures and coastal processes. For the first time, scientists and policymakers would be able to quantify natural and built infrastructure response under conditions that mirror the power of hurricanes.

“The envisioned NICHE responds directly to one of the biggest societally driven challenges of the 21st century, addressing the vexing impacts from natural hazards to ensure communities, infrastructure and natural environments continue to thrive,” says Arindham Chowdhury, principal investigator of NICHE.

NICHE is being designed as a full-scale facility to solve problems of scaling. Conventional testing, for example, may produce inaccurate results when scaling down a coastal low-rise building to investigate hazard impacts or miniaturizing sand particles to study beach erosion. This is because a wooden beam or a nail or a window cannot be scaled down properly to investigate damage under wind and water, explains Chowdhury, just as a sand particle cannot be scaled down without losing its inherent properties that govern particle transport.

Designed to produce 200 mph winds and 16-foot waves, the facility would allow experts to evaluate structural performance and coastal processes in ways no laboratory has done before. Its immersive physical-digital visualizations, including regional simulation tools, would enable stakeholders to step inside simulated storms to understand their impacts on communities while determining the efficacies of innovative solutions to impart resilience. They’ll be able to test mitigation strategies and even preview how proposed building-code reforms might perform when extreme weather strikes, making it a decision-making platform for communities, industry and government.

“NICHE’s combination of full-scale testing capabilities and a robust Artificial Intelligence component will be unmatched when built, really setting this facility apart,” says Jack Puleo, associate vice president for strategic initiatives in coastal engineering and resilience at FIU.

“We need unscaled capability so that we can attempt to solve engineering problems as they exist in reality. AI can be used as a predictive tool, but importantly, AI is data hungry. Predictions are only as good as the data being fed to the learning algorithms,” he continues. “Thus, the AI aspect will be iterative as new physical simulations are conducted, leading to improved and never-before-obtained observations/data.”

NICHE promises meaningful economic impact. Advancing hightech building materials, accelerating product commercialization,  strengthening the nation’s resilient construction sector and innovating nature-based coastal protection, the facility would help position the United States as a global leader in disastermitigation technologies. Its insights could influence insurance models, reshape policy discussions and ultimately support safer, stronger and more prosperous coastal communities.
