Researchers study Puerto Rico hurricane to understand impact of New England storms on watersheds

Researchers used high-frequency sensors, a new technology, at sites such as this one to assess stream chemistry at 15-minute intervals before and during Hurricane Maria. Their goal was to learn how and where solutes, such as salt, and sediment, such as sand and silt, are stored in watersheds and how these reservoirs respond to such massive storms. (COURTESY PHOTO)

DURHAM — Large, extreme events such as hurricanes and superstorms are becoming more frequent under a changing climate. Researchers with the New Hampshire Agricultural Experiment Station at the University of New Hampshire are looking to new findings from a major hurricane in Puerto Rico to understand how large storms may affect New England watersheds, streams and river networks.

“New England, including New Hampshire, often receive significant precipitation due to hurricanes that travel up the Eastern seaboard. While the region’s terrain and vegetation are different compared with Puerto Rico, these results give researchers an initial predictive framework to understand local watersheds,” said Adam Wymore, research assistant professor of natural resources and the environment.
