Dear DVGI Members and Friends,
DVGI invites you to our September 2022 dinner meeting. The meeting will feature the ASCE Geo-Institute Cross-USA Lecture Tour speaker, Dr. Timothy D. Stark. Dr. Stark's topic for the meeting will be theOso, Washington Landslide: Failure Mechanism and Runout Analysis.A presentation abstract and speaker bio is below.
Social hour will start at 5:30PM followed by dinner at 6:30PM with the presentation to follow.
We anticipate that 1 PDH will be awarded for attending.
Please note our vendor is requiring more advance notice for headcount than the past, therefore the registration deadline is Tuesday September 13, 2022.

Presentation Abstract
Professor Stark will present an update of his study of the 22 March 2014 Oso landslide near Oso, Washington. This major and tragic landslide exhibited some interesting aspects of geo-mechanical behavior and is contributing to a better understanding of landslide triggering mechanisms and improved methods of runout analyses for hazard and risk assessments. This study evaluates the accuracy of three runout software packages, DAN3D, Anura3D, and FLO-2D, for modeling the runout of the 2014 Oso landslide and investigates the viability of predicting the runout of other landslides and slope failures, such as, tailings dams. These analyses show the importance of: (i) using a digital terrain model in the runout analysis, (ii) modeling field representative shear strength properties and failure mechanisms, and (iii) predicting runout distance, splash height, and duration to improve public safety.
