Once called “hundred year floods,” severe flooding events in Vermont are becoming increasingly common. This past July, floodwaters swept through many Vermont towns and caused an estimated $1 billion in damage to homes, businesses and farmland. The flooding also led to two deaths.

Many floodplain maps are made by the Federal Emergency Management Agency. If you have flood insurance for your home, it might be because one of these FEMA maps says your property is at risk. But many FEMA maps are out of date and only cover populated areas.

To really understand the flow of water, scientists agree we need to map more of our region.

Researchers at the University of Vermont are creating and training computer models to predict how water will flow through the landscape during a flood. They’re collecting data from floodplains across the Champlain Valley to feed their algorithms.
