Variations in Earth’s surface water play a crucial role in the global hydrological cycle. Unexpected changes such as flooding are among the most devastating natural hazards, endangering millions of lives and livelihoods worldwide with the impact enhanced as socioeconomic vulnerability increases. Mitigating these impacts is a key priority for government agencies and industries like insurance. As flooding becomes increasingly complex and its impact more challenging to pinpoint, even with growing data availability, the most vulnerable and underserved communities remain at high risk of impact as climate, socioeconomic, and political drivers of risk continue to evolve.
