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)
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
