Debris Flow Assessment, Analysis and Mitigation Debris flows are prevalent in regions characterised by steep terrain and periodic episodes of intense or sustained rainfall. Due to their high velocities, substantial impact forces, extended travel distances, and unpredictable occurrence, debris flows represent one of the most…
Torlesse greywacke is the most prevalent of New Zealand’s basement rocks and is frequently encountered during civil construction projects, particularly in the Wellington region, the Southern Alps, and Marlborough. Unit 7C.2 builds on the slope stability principles discussed in previous units by providing detailed commentary…
The affairs of the NZ Geotechnical Society are managed by the Management Committee on behalf of the Members. We aim for representation on the Committee that is as broad as possible both geographically and between engineers and geoscientists to ensure that all views are well…
iRALL (International Research Association on Large Landslides) is inviting PhD students, post Docs and early career post graduates working in industry to their 10th summer school. THis will be hosted in Chengdu, China, in the second half of September. For more information see https://sklgp.cdut.edu.cn/irall/info/1025/1345.htm
Following numerous requests for clarification on load factors and solved example outputs, significant updates regarding MBIE/NZGS Module 6 (Rev1) is planned in consultation with SESOC and MBIE. In the interim, a clarification documented has been prepared for our members ahead of the revision of the…
Mitigation and Design Principles Unit 4 of the Slope Stability Guidance provides guidance on effective strategies for mitigating slope instability by addressing both engineered and non-engineered solutions. It outlines risk-based approaches tailored to site-specific conditions and includes considerations for slope stability design, performance criteria, and…
The New Zealand Geotechnical Society is excited to propose Christchurch as the host city for the 17th ISRM Congress in 2031 under the theme: “Shaping a Sustainable Future in Rock Mechanics and Rock Engineering”. With the dynamic geology, the unique natural laboratory, and a culture of…
Unit 3 builds on the guidance in Part 7 of Unit 1 and centres on assessing landslide triggers in soil and rock slopes using limit equilibrium methods (LEM). These methods are commonly used in New Zealand and worldwide for routine projects because they provide reliable…
Recording of the 24th Glossop Lecture: Landslide Risk Assessment: Radical Uncertainty and Engineering Geomorphology 17 February 2025 . Presented by Dr. Mark Lee, Ebor Geoscience Limited, York View HERE Abstract: Assessment of landslide risks requires an understanding of how future landslide behaviour (the hazard) could…
When planning any new development on or near slopes, it is essential to consider the potential for landslides, both past and future. The initial stage of any landslide investigation involves recognizing and identifying the type of landslide. This step is crucial as it determines the…
