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…
