For our assessment, the region of Port Alberni, Alberni Inlet, and Somas River were analysed using digital elevation models (DEMs) to classify four distinct sources of risk and combine them to create ...

Image processing is being used to improve the topographic maps for use in the slope stability and hydrological modeling. Slope stability models also require the strength properties of the soils which ...

and lidar-derived topographic slope. Sheet maps are included with the study that show slope failure in several different time frames in different color coding: pre-1952; 1975 to mid-1980s ...
