Flood findings: Tropical Storm Irene informs Dartmouth student’s study of rivers
Jordan Fields, a doctoral student of fluvial geomorphology, left, and Dartmouth College senior Shannon Sartain, right, work together to plot changes to the channel of Charles Brown Brook in Norwich, Vt., Wednesday, April 14, 2021. Fields is studying the recovery of the site following the 2018 removal of a dam built almost 100 years earlier. (Valley News - James M. Patterson) Copyright Valley News.

The number of extreme streamflow events observed in river systems across the United States and Canada has risen significantly over the last century, according to a Dartmouth study published in
Although changes in precipitation and extreme streamflows have been observed in the past, there has been no consensus on whether droughts and floods have actually increased in frequency. According to the study, the results demonstrate that increases in the frequency of both high- and low-flow extreme streamflow events are, in fact, widespread.
