Explore the catastrophic flooding and geological impacts of Hurricane Helene's remnants in the southern Appalachian Blue Ridge through this geological presentation by Dr. Ryan Thigpen from the University of Kentucky. Learn about the unprecedented rainfall event from September 26-29, 2024, that produced over 30 inches of precipitation and caused rivers like the Nolichucky and Swannanoa to reach flow rates 300 times their normal levels, surpassing historic flood records. Examine thousands of slope failures and some of the largest and deadliest debris flows ever documented in the eastern United States through on-the-ground photos, videos, and preliminary survey results collected just five days after the disaster. Discover how widespread bank erosion exposed previously unknown paleo-flood and landslide deposits, including evidence of what may be the largest magnitude flood event in the last 10,000 years. Understand how researchers are integrating ground surveys, LIDAR technology, and photogrammetric analysis to quantify recurrence intervals of past extreme events and develop better mountain flood warning systems. Gain insights into the conditions that trigger catastrophic debris flows and the Holocene record of extreme flooding and geological events in the southern Appalachians, contributing to improved understanding of natural disaster patterns and preparedness in mountainous regions.
