Terrain Map and Erosion Processes EENG 8801

Upon successful completion, the student will be able to:

• Read terrain maps, terrain stability maps and other interpretive maps, and be aware of how these maps should and should not be used.
• Read terrain map symbols with the aid of a map legend (BC Terrain Classification System).
• Describe the physical characteristics of the common surficial materials and demonstrate how these relate to the material's original mode of deposition.
• Indicate how surficial material characteristics and properties are significant with regard to land use and engineering activities.
• Recognize the common geomorphic processes (e.g., debris flows, snow avalanches), and be aware of the potential effects of these processes on land use and the potential influence of land use on these processes.
• Distinguish the different types of geomorphic processes and describe the chief controls on slope stability.
• Distinguish terrain maps from interpretive maps.
• Describe how interpretive maps are prepared, and give examples of the types of criteria that are used for standard interpretations.
• Carry out simple interpretations for slope hazards and constraints to road construction.
• Illustrate how terrain information can be used to make decisions about road building and cutblock locations, and how, in general, it can be applied usefully to land use planning and resource management.
• Assess the reliability and limitations of terrain maps and related interpretive maps.
• Draft the terms of reference for a terrain stability mapping project.
• View air photos under a stereoscope and recognize features shown on a terrain map of the same area.
• Identify surficial materials exposed in road cuts, using a terrain map of the area as a general guide.
• Apply terrain information to environmental management and resource planning.
• Be aware of current legislative requirements or policy for terrain mapping and interpretations.
