Course in Cold Regions Hydrological Modelling
Geography 898.1 T1

Professor John Pomeroy, Dept of Geography (e-mail) 12.1 Kirk Hall

Department Approval Required: must be taken for credit

September 4-5, 2013
Enrollment Limit: 40

Course Objectives
This course aims to:

  • Familiarize students with the principles of object-oriented physically-based hydrological process modelling for the cold regions of western and northern Canada

  • Train students to use the Cold Regions Hydrological Modelling Platform (CRHM) to create purpose built hydrological models that are appropriate for hydrological prediction problems in western and northern Canada

On completion of this course, students should be able to:

  • Describe which physical process algorithms are most appropriate for modelling forested, prairie, mountain and arctic river basins under various levels of meteorological and parameter data availability

  • Use CRHM to construct and run an appropriate hydrological model for small river basins in western and northern Canadian environments

Contact Hours and Schedule
Lectures and practical sessions will take place intensively over a two-day period, followed by time for questions and review

Students must -

  • Have taken an upper-year undergraduate physical hydrology class by the time this course begins

  • Be comfortable with numerical methods as applied in physical hydrology

  • Have a laptop computer, and be able to install software provided by the instructor
    Note - Software will run on Microsoft Windows (up to Win7), Apple Intel Macintosh (NOT PowerPC), or Linux (Wine required)

Course Outline

  • Day 1, AM: Principles of cold regions hydrological modelling
  • Day 1, PM: CRHM features and operation
  • Day 2: CRHM Operation Tutorial (exercises assigned)

Marking and Evaluation
Marks will be awarded as follows:

  • 20%: active participation in the class tutorials
    evaluation: successfully installing and running CRHM model on own laptop

  • 80%: quantitative exercises on hydrological modelling
    evaluation: exercise to develop a hydrological model using CRHM and apply it to snowpack, soil moisture and predict streamflow in a basin
