Terrain Stability Mapping and Hazard Assessments

Terrain stability mapping is a widely-used, highly specialized application used during the layout stage of access corridors for resource development. Our geoscientists have performed detailed terrain stability mapping and hazard assessments for:

• Proposed roads
• Proposed mine sites
• Transmission corridors
• Timber blocks
• Sediment source inventories
• Debris-flow hazard studies
• Log sorts and landings
• Site surveys for landfills

When considering development or resource extraction on varied terrain, many factors combine to create complexes of terrain features. Surficial materials, slope gradients, soil drainage, erosion hazard potential, landslide-induced stream sedimentation, and timber blowdown are just some of the terrain attributes used in terrain stability mapping and hazard assessments. These are valuable tools in identifying potentially unstable terrain, and managing the associated risks.

Our professionals are experienced in mitigation planning based on the results of our terrain analysis and can include prescriptions for erosion and sediment control, landslide and gully rehabilitation, as well as road concept design and construction. We assist our clients in minimizing the potential risks and optimizing safety.
