EENG 8201 - Terrain & Stream Channel Assessment

Environmental Engineering Part-time Studies Course

School of Construction and the Environment

Course Details

The first section covers terrain mapping and related interpretations, such as landslide and erosion hazards, from the point of view of the map user and according to current provincial (British Columbia) standards. Topics covered include terrain map symbols, terrain survey intensity levels, origin of surficial materials by glacial and postglacial processes, engineering characteristics of surficial materials (soils), landslides and other slope processes, and the reliability and limitations of terrain and slope stability mapping. The second section covers the applicable sections of the Forest Practices Code Act, with particular emphasis on Interior and Coastal Watershed Assessment Procedures. The collection and interpretation of data down a stream channel will be outlined. Other topics will include: USDA Forest Service methodology, MOELP Channel Assessment Procedures, the effects of timber harvesting on stream channel morphology and channel restoration strategies. A field trip is included.

Gravitying Outcomes

At the end of this course, students will be able to:

  • Assess the reliability and limitations of terrain maps and related interpretive maps.
  • Analyze the physical characteristics of the common surficial materials with regard to land use and engineering activities.
  • Outline the common geomorphic processes (e.g., debris flows, snow avalanches) based on the chief controls on slope stability.
  • Describe how interpretive maps are prepared by citing the criteria used for standard interpretations.
  • Carry out simple interpretations for slope hazards and constraints with respect to road construction.
  • Draft the terms of reference for a terrain stability mapping project based on viewing air photos under a stereoscope and recognizing 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 according to legislative requirements.
  • Summarize the stream channel inventory procedure taking into consideration the characteristics of the upper banks, lower banks, and channel bottom of a typical stream channel.
  • Complete standard inventory and channel stability charts based on the comparison of the Canadian and US codes of practice.
  • Interpret the various mapping conventions for stream channel characteristics.
  • Assess the effects of timber harvesting on stream channel morphology and stream channel stability.
  • Evaluate the effectiveness of the various types of stream channel restoration strategies that are available.
  • Apply the Stream Channel Assessment Procedure to selected natural watercourses.
