Snow Avalanche Risk Assessment and Mitigation
This webinar identifies aspects of snow avalanches that differ from other geohazards and how this affects assessment and mitigation methods. Selected methods for characterizing avalanche terrain and extreme snow avalanches are outlined, and examples of assessment and mapping methods are presented, along with mitigation methods that include structural defences and remote avalanche triggering.
Presented by: Bruce Jamieson, PhD., P.Eng and Chris Wilbur, P.E.
Sediment and Large Wood Trapping Structures: Best Design and Functional Approach
Sediment and large wood trapping structures used in debris-flows and debris-flood mitigation schemes are described in this webinar. The driving mechanisms of deposition and erosion processes at the fan scale and at the structure scale are introduced to assist engineers in selecting the best type of structure for a given site and to design its shape and geometry.
Presented by: Guillaume Piton, Ph.D.
Geohazard Mapping and Monitoring - The Road to Proactive Engagement and Solution Provision
This webinar presents current trends and technologies in multi-instrument data acquisition, analysis and reporting in the geotechnical asset and geohazard fields. These include UAS, LiDAR, Photogrammetry, GbSAR, SatSAR, Microseismic, DFOS, and GNSS. Practice suggestions are presented for realizing the benefits of multi-sensor acquisition deliverables, and the mapping and monitoring benefits that result.
Presented by: Pieter Bas Leezenberg, Paolo Mazzanti, and John Metzger
RocFall: Statistical Analysis of Rockfalls by Rocscience
This webinar introduces Rocscience’s 2D statistical analysis program RocFall. The software simulates rockfall energy, velocity and ‘bounce height’ along a slope profile to assist in rockfall risk assessment and mitigation design. A RocFall model is developed with a focus on barrier/berm analysis, barrier sensitivity analysis, and design reports.
Presented by: Ellen Yeh
Selection and Testing of Ground Reinforcement and Ground Anchorage Systems - Matching CQA and Testing to Installed Components
Ground anchors and ground reinforcement members are often constructed of similar materials; despite their difference in loading and function. This webinar discusses PTI testing, anchor components, testing of complex & simple anchors, and the applicability of such testing to rock reinforcement such as tensioned Rock Bolts and passive Rock Dowels.
Presented by: David Scarpato, PE, Martin Woodard, Ph.D., P.G., PE, Peter C Ingraham, PE
Flexible Debris Flow Barriers: Research Background, Design Approach, and Limitation
Debris Flow Barriers are containment systems that can be designed and dimensioned to withstand the high dynamic loads of channelized debris flows and shallow landslides. This Webinar takes a close look at what’s commonly known about debris flow behavior, the critical parameters, the load concept, and design considerations when selecting a mitigation solution.
Presented by: Nadine Feiger and Saleh Feidi
Ground Anchoring 201: Beyond the Basics
This webinar will provide an overview of commercially available anchoring products & their typical applications. Furthermore, the webinar will focus on important technical aspects of anchor design and selection including Specification Compliance, Geotechnical Design Considerations, Mechanical Properties, Longevity & Corrosion Protection, Anchor Economics & Practical Commentary that reflect the current state of practice in ground anchoring.
Presented by: Tom Bird and Pete Speier
Grouting Background, Techniques, Applications and Project Examples
This presentation will discuss grouting basics and delve into the background behind various grouting techniques, pointing out design and planning considerations. Various project examples and operational tips and tricks will be discussed.
Presented by: Jarrod Hartshorn and Damien Bosse
Large Area Flood, Steep Creek, and Landslide-Dam Flood Risk Prioritization
This webinar will present approaches to prioritize geohazard risk across large and typically data-scarce regions like British Columbia and discuss how their results support development planning, regulation, and emergency management.
Presented by: Kris Holm
Hollow Bar Anchors - A Technical Discussion on Proper Specification and Installation
This webinar discusses details unique to the hollow bar system. The presenters cover recent research conducted through the Federal Highway Administration, emergence of the system in governing specifications, and discuss what seems to be the main issue with permanent hollow bar anchors: long-term durability.
Presented by: Tom Bird and Jeff Pendleton
Early Warning and Detection of Large Landslide Events Using Ground-Based and Satellite Interferometric Radar - A case study at Roberts Mountain, Oregon
This webinar provides a look into using real-time ground-based interferometric synthetic aperture radar (GB-InSAR) system to successfully early warn on landslide movements prior to failure for use in safety critical scenarios. Located along Interstate 5, this Oregon Department of Transportation project included both interstate widening and landslide remediation.
Presented by: Cody Stopka, Jill DeKoekkoek, Pete Castro, and John Metzger
Remote Sensing Tools for Identification and Monitoring of Geohazards
