USBR Crack the Case Challenge

—

## NASA and USBR Launch a High‑Stakes Call for Innovation
The U.S. Bureau of Reclamation (USBR) is responsible for more than 8,000 miles of canals and 492 dams across the western United States. Many of these structures are decades old, and while they are closely monitored, early crack detection remains one of the most technically difficult aspects of dam safety.

To accelerate progress, NASA’s Center of Excellence for Collaborative Innovation (CoECI) and its NASA Tournament Lab (NTL) have partnered with USBR to launch the “Crack the Case” Challenge. The multi‑phase competition invites experts in geophysics, sensing, nondestructive testing (NDT), materials science, and artificial intelligence to propose innovative ways to detect internal cracking before it leads to large‑scale structural damage.

This challenge is part of a broader trend in federal agencies using open innovation and crowdsourcing to solve specialized technical problems. The concept is simple: bring together diverse thinkers—both inside and outside traditional engineering domains—to generate solutions that may not emerge through conventional research pathways.

## Why Early Crack Detection Matters
Massive concrete structures such as dams experience constant physical stress. Temperature changes, shifting foundations, repeated loading, and long‑term material fatigue can all cause microcracks. These tiny fractures are often hidden deep within concrete blocks and may not appear on external surfaces until the damage becomes significant.

While routine inspections and instrumentation already provide valuable data, today’s tools still struggle with:

– Pinpointing subsurface cracks in thick concrete sections
– Differentiating harmless microcracks from dangerous structural fractures
– Producing actionable, high‑resolution information for engineers
– Scaling methods to entire dams, not just small test areas

Advances in sensing technologies, signal processing, and AI‑based pattern recognition have begun to show promise. However, no single method has emerged as a practical, reliable, and affordable standard. The Crack the Case Challenge aims to identify concepts that could evolve into field‑ready solutions.

## How the Challenge Works
The Crack the Case Challenge is structured to filter ideas from broad concepts to feasible solutions. While NASA and USBR have published only high‑level details so far, the challenge is known to include three phases:

### Phase 1: Conceptual Proposals
Participants submit high‑level solution concepts. These can include emerging sensing approaches—such as acoustic monitoring, thermal imaging, advanced radar, or distributed fiber‑optic systems—and hybrid methods that combine multiple data sources with machine learning.

The goal of this initial phase is to cast the widest possible net, encouraging participation from fields that might not traditionally be connected to dam engineering. AI researchers, spacecraft instrumentation designers, and medical imaging specialists may all bring valuable new perspectives.

### Phase 2: Prototype Development
Selected teams advance to build early prototypes or simulations demonstrating the feasibility of their method. This stage emphasizes data quality, noise reduction, detection sensitivity, and practical deployment considerations such as sensor placement and long‑term durability.

### Phase 3: Testing and Validation
Finalists put their solutions through more rigorous testing based on USBR’s criteria. The best-performing approaches may be considered for further research or pilot deployment at real dam sites.

## NASA’s Role: Innovation Infrastructure, Not Dam Operations
Although NASA is not responsible for dam safety, it plays a crucial role by enabling innovation across federal agencies. CoECI and the NASA Tournament Lab have decades of experience running technical challenges that draw thousands of global participants. These programs have contributed to advancements in Earth observation, autonomous robotics, and remote sensing—skills that translate well to structural monitoring problems.

For USBR, partnering with NASA enables access to a broader pool of innovators and a proven framework for managing crowdsourced R&D initiatives.

## What Makes This Challenge Significant
A breakthrough in early crack detection would have far‑reaching benefits:

– **Improved Infrastructure Safety**: More accurate and earlier warnings give engineers time to repair damage before it becomes dangerous.
– **Lower Maintenance Costs**: Better data allows agencies to target repair budgets where they’re needed most.
– **National Resilience**: Many dams support drinking water, hydroelectric power, and agricultural irrigation. Strengthening their monitoring systems supports long‑term stability.
– **Cross‑Industry Applications**: Any innovation in nondestructive testing could apply to bridges, tunnels, levees, and large industrial structures.

Because concrete aging is a universal challenge, successful solutions could even find applications in offshore wind turbines, spacecraft landing pads, and planetary habitat construction—fields where NASA itself has future interests.

## How Potential Participants Can Prepare
While the challenge is still early in its release, innovators can begin gathering resources and evaluating possible approaches. Some useful areas of preparation include:

– Reviewing existing nondestructive testing techniques, such as ground‑penetrating radar, ultrasonic pulse velocity, or acoustic emission monitoring.
– Exploring AI-driven methods for identifying anomalies in noisy or incomplete datasets.
– Studying environmental effects—such as moisture and temperature—that influence signal behavior inside concrete.
– Considering how sensor networks might be deployed on large, complex structures.

Solutions will need not only technical sophistication but also practicality. A fully field‑deployable approach must be durable, energy‑efficient, and cost-effective for widespread adoption.

## Broader Context: Crowdsourcing as a Federal Research Tool
The Crack the Case Challenge reflects a growing recognition that “open innovation” accelerates problem‑solving. Agencies such as NASA, NOAA, and the Department of Energy have used public challenges to:

– Improve satellite data processing
– Design next‑generation space robotics
– Enhance climate modeling techniques
– Develop novel materials and manufacturing concepts

These programs frequently uncover solutions unexpected by traditional research pipelines. They also offer cost‑efficient ways to explore a wide landscape of ideas before committing to full-scale development.

## Looking Ahead
The next steps will involve the release of more detailed challenge documentation and guidance for applicants. As the challenge progresses through its three phases, USBR and NASA will likely share updates highlighting promising approaches and technical insights gained from the submissions.

Whether the winning solution comes from a seasoned geophysicist, a machine learning specialist, or an interdisciplinary team, the Crack the Case Challenge has the potential to advance the science of monitoring America’s critical infrastructure.
