In this article for The Conversation, U-M researchers highlight the growing threat of flooding in the U.S. driven by climate change and the limitations of existing flood monitoring systems, which leave many areas without reliable data. The faculty experts emphasize the need to expand flood monitoring through affordable, easy-to-deploy sensors and better data integration to improve flood predictions, warnings, and community preparedness. Engineers at the University of Michigan Digital Water Lab have developed such sensors for real-time water level monitoring, offering a promising solution to bridge these data gaps.
