TEDx Talks - What can self-driving cars teach us about addressing coastal flooding? | Branko Kerkez | TEDxBoston
Flooding is a frequent and costly disaster, causing significant human and economic losses. Current infrastructure is outdated and often invisible, leading to inefficiencies in flood management. The integration of AI and sensor technology can revolutionize how cities manage water systems. By installing sensors to monitor water levels, soil moisture, and rainfall, cities can dynamically adjust infrastructure to prevent flooding. This technology is already being adopted in places like New Orleans, where sensor networks provide real-time data, allowing for proactive measures that can significantly reduce damage costs. For example, predicting floods 24 hours in advance can save up to 30% in damages. Additionally, retrofitting existing infrastructure with internet-connected devices can enhance performance, making it as effective as doubling the size of static infrastructure. This approach is cost-effective and scalable, applicable from neighborhood to city-wide levels, and even entire river basins. The data collected can also be used post-flood to improve future planning and engage communities in city development through interactive digital models.
Key Points:
- AI and sensors can dynamically manage water systems to prevent flooding.
- Predicting floods 24 hours in advance can reduce damage costs by 30%.
- Retrofitting infrastructure with sensors can double its effectiveness.
- Digital upgrades are cost-effective and scalable from neighborhoods to river basins.
- Engaging communities with interactive digital models can improve city planning.

6. 🚧 Dynamic Infrastructure Management
- Existing infrastructure can be retrofitted with internet-connected valves, pumps, and gates to control water flow and prevent flooding.
- Studies have shown that dynamically managing water through a city can increase infrastructure performance by acting as if it's twice as large as static infrastructure.
- Retrofitted infrastructure with sensors and analytics can be built at half the size, offering significant cost savings.
- Digital upgrades can be two to four times more effective than static assets at a fraction of the cost.
- This approach is applicable on both neighborhood and city scales, including large sewer systems serving millions of people.
- Using sensors and inflatable devices, such as pillows in sewer pipes, can act as underground dams to manage water flow effectively.
7. 🌐 Large-Scale Infrastructure Control
- Utilities worldwide are strategically investing in digital solutions as part of a comprehensive resilience portfolio, highlighting the critical role of technology in modern infrastructure management.
- Digital technology enables the scaling of infrastructure control to the level of entire river basins, demonstrating its potential for extensive environmental management and monitoring.
- Historically, dams have been viewed as environmental liabilities due to issues like flooding and habitat disruption, but this perspective is shifting with technological advancements.
- Retrofitting river basins with advanced monitoring and modulation devices transforms dams from liabilities to assets, enhancing ecological conditions and benefiting local communities.
- This approach facilitates natural-like river modulation during floods, addressing both ecological and human needs, and showcasing the dual benefits of integrating advanced infrastructure technologies.
- Case studies from different regions show that integrating digital solutions in river basin management has led to improved ecological outcomes and community benefits, reinforcing the strategic value of these technologies.
8. 🎮 Digital Models and Community Involvement
- Digital models of cities are evolving to be interactive, similar to video games, allowing residents to engage and share their visions for urban development.
- Community input, alongside planners and engineers, is critical in calibrating digital models using data from flood events.
- Despite digital solutions' potential for enhancing flood management, the water sector lacks investment compared to transportation and energy.
- Water managers are eager about technological advancements but find AI to be costly and rapidly changing, indicating a need for continuous dialogue to meet their needs.
9. 🗣️ Engaging the Tech Community in Water Management
- Encourage collaboration between tech experts and water management professionals to develop usable solutions.
- Facilitate open conversations and partnerships to drive innovation in water management.
