Free Lecture Thursday November 17th

November 17th: Mathias Collins
NOAA/National Marine Fisheries Service, Gloucester
“Historical Trends in New England River Flooding and What is Happening Lately”
Lectures are held at 7 PM, Friend Room, Sawyer Free Library
Mathias has published some great research showing that the size and frequency of large floods have increased dramatically over the last 30-40 years. Smaller floods have increased too. Huge implications for our aging dams and also for culvert, bridge, and storm water design.
