MIT scientists have developed a cutting-edge method combining artificial intelligence and physics to predict and visualize future flooding events. This innovative approach not only forecasts storm impacts on specific regions but also generates realistic satellite images depicting the aftermath, transforming how communities prepare for disasters by offering a more precise visualization of risks.


The method integrates a generative AI model with a physics-based flood model to create detailed images of areas likely to flood, depending on the intensity of an approaching storm. As a proof of concept, the researchers applied this technique to Houston, generating images of the city under conditions similar to Hurricane Harvey in 2017. These were compared to authentic satellite and AI-generated images without a physics-based model.

The results were significant. The physics-reinforced AI method closely matched actual flooding patterns, while the AI-only method produced less reliable images, including unrealistic depictions of flooding in high-elevation areas. This demonstrates the potential of blending generative AI with physics to produce trustworthy insights, although broader applications require further training on diverse satellite images. Named the “Earth Intelligence Engine,” this tool is available online for public use, with findings published in IEEE Transactions on Geoscience and Remote Sensing.


A significant motivation for this work is to improve evacuation readiness during severe weather events. Björn Lütjens, the study’s lead author, explained that visual tools like these could encourage timely precautions. This technology could complement existing flood maps by providing realistic and engaging flood depictions, making risks more tangible.

The method uses conditional generative adversarial networks (GANs) consisting of two neural networks: a generator and a discriminator. The generator trains on real data pairs, such as satellite images before and after hurricanes, while the discriminator learns to identify actual versus generated images. This interplay creates highly realistic images, though GANs can produce “hallucinations,” or incorrect features, in generated outputs.


The team incorporated a physics-based flood model accounting for storm trajectories, wind patterns, storm surges, and local infrastructure to address this. This integration eliminated inaccuracies, producing reliable flood visuals and highlighting the value of merging machine learning with physics in risk-sensitive scenarios.


The broader goal is to equip communities and policymakers with tools for informed decision-making. Before hurricanes, this technology could add a critical visualization layer, complementing forecasts and helping residents grasp neighborhood-specific impacts. Researchers believe this could save lives by improving preparedness and encouraging evacuations.

Senior author Dava Newman emphasized the importance of hyper-local perspectives on climate impacts. By focusing on familiar areas like zip codes, the researchers aim to make data more relatable. Newman, a professor at MIT and director of the MIT Media Lab, advocates for combining scientific rigor with personal relevance to improve communication.


The Earth Intelligence Engine was supported by the MIT Portugal Program, DAF-MIT Artificial Intelligence Accelerator, NASA, and Google Cloud. Researchers aim to refine and expand the tool, making it a reliable resource for decision-makers. With further advancements, this technology could become a cornerstone of disaster preparedness, enabling communities to visualize risks and act proactively to protect lives and property.
