Timescales of Recovery from Erosive Floods in a Changing Climate
Brian Yellen, University of Massachusetts at Amherst

Historical precipitation, groundwater, and streamflow records show that the Northeast United States is getting wetter, but what does this mean for extreme flooding and erosion? This talk examines sediment cores and stream monitoring records to tease out the relationship between wetter regional conditions and watershed erosion. Results indicate that short-duration flood events have lasting effects on water quality, with persistently elevated turbidity following extreme floods. Furthermore, as our climate gets wetter, erosive events are increasing in magnitude independent of extreme flood frequency due to wetter soils that erode more readily.

The Hudson River Watershed Alliance's Annual Watershed Conference theme was Climate Change Impacts on Water in the Hudson Valley. For more information: https://hudsonwatershed.org/annual-wa...

This presentation was part of the virtual session of the conference, which focused on current regional information on climate change projections and impacts, including drought, flooding, stream channel erosion, and climate equity. This information provided context for decision-making and planning for climate resilience, with a focus on water resources.

This presentation was recorded on October 24, 2022.
