A Rice University-led team of climate scientists and engineers is studying how climate change will impact the frequency and severity of flooding on the Mississippi River thanks to a new grant awarded by the National Science Foundation.
“The real question motivating our research is: How will climate change alter the frequency and magnitude of flooding on the river?” said Rice’s Sylvia Dee, the principal investigator on the three-year grant to her lab and those of co-principal investigators James Doss-Gollin at Rice and Samuel Muñoz at Northeastern University.
More than a quarter of the U.S. population lives within the Mississippi River watershed, an area larger than 1.2 million square miles that includes the drainage basins of tributaries like the Missouri, Ohio, Arkansas and Tennessee rivers.
Climate warming will promote both drought and intense rain, because warmer air that is dry will parch soil more quickly, increasing evaporation, but warmer air can also hold more moisture, leading to more extreme rainfall. Dee said uncertainty remains about which of these effects will dominate and when. And flood risk managers need that information to plan appropriately for the coming century.
