Why Flash Flooding Is of Increased Local Concern
Jase Bernhardt, associate professor of geology, environment, and sustainability, was interviewed by Newsday about the increased risk of flash flooding on Long Island. The article explains that flash flooding is caused by heavy rainfall in a short period. It’s often caused by thunderstorms in the summer, when there’s more moisture in the air than in cooler months. It can happen anywhere across the region, as opposed to storm surge flooding, which mostly impacts low-lying coastal areas. Any change in the frequency of flash flooding on Long Island is also a function of the way water moves on the ground and ultimately of urbanization, Dr. Bernhardt said. “Poor drainage, sewer systems” and impervious surfaces like “parkways, parking lots” and other types of development all play a role.
