OBF February 2026 Webinar - Paul Morgan

Webinar: Landslide Dams

Wednesday, March 4th 6:00pm

This virtual event is free and open to all. 

In this talk, Paul Morgan, PhD candidate at the University of Washington, will introduce landslide dams through a few examples from the US and around the world, briefly go over his new methodology called 'the damability function', and summarize his findings for rivers in the Oregon Coast Range. He found widespread high damability especially where rivers flow through steep mountains with strong rocks.  Fortunately, most damable river sections are on small rivers, where dams would only impound small lakes, and generate weak floods. However, he did identify some river sections with higher hazard potential, specifically a few river sections where very large landslides could impound dangerously large lakes.
