More Pavement, More Problems

Think your daily coffee, boutique gym membership and airport lounge access cost a lot? There may be an additional, hidden cost to those luxuries of urban living, says a new Johns Hopkins University study: more flooding.

For every percentage point increase in roads, parking lots and other impervious surfaces that prevent water from flowing into the ground, annual floods increase on average by 3.3%, the researchers found.

UCI, other researchers find collaborative flood modeling process effective

Irvine, Calif., Jan. 21, 2020 – Community collaboration and high-resolution maps are key to effective flood risk management, according to civil engineers and social scientists at the University of California, Irvine and other institutions. In a study published recently in the American Geophysical Union journal Earth’s Future, the researchers report on a successful new process called “collaborative flood modeling” for addressing the increasing threat of rising waters brought on by climate change, aging infrastructure and rapid urban development.

Researchers study impact of contaminants in floodwaters

Last spring’s historic flooding along the Missouri and Mississippi rivers may have distributed toxic contaminants along wide flood routes. Researchers know little about how these materials may affect public health and safety in rural and urban areas. But a group of geologists and geological engineers from Missouri University of Science and Technology is working to find out.

Plant physiology will be major contributor to future river flooding, UCI study finds

Irvine, Calif., Oct. 21, 2019 – The next time a river overflows its banks, don’t just blame the rain clouds. Earth system scientists from the University of California, Irvine have identified another culprit: leafy plants. In a study published today in Nature Climate Change, the UCI researchers describe the emerging role of ecophysiology in riparian flooding.
