Canadian Rockies Hydrological Observatory - Saskatchewan River Basin

The Canadian Rockies Hydrological Observatory is a major project by the Centre for Hydrology and partner organizations to improve understanding and prediction of hydrometeorological and cryospheric phenomena in the Canadian Rocky Mountains. It aims to:

  • Advance development and integration of information on how hydrological and cryospheric processes interact to form streamflow
  • Develop and run hydrological models to produce water resource predictions for past and future climates.

Principal Research Questions

  1. How do mountain basin biophysical characteristics affect snow and ice systems to produce hydrological responses to precipitation and energy inputs on time scales from hours to centuries?
  2. Do cold regions mountain hydrological systems enhance or dampen the effects of climate variability on water resources?
  3. Are the Canadian Rocky Mountains a reliable future source of streamflow?

Principal Objectives

  1. Improve understanding and description of governing processes for mountain water supply
    • Snow and glacier cold regions processes
    • Ecohydrological processes
    • Sub-surface processes
  2. Improve modelling of mountain hydrological systems
    • Small scale distributed physically based simulations
    • Moderate scale headwater catchment models
    • Large scale river basin and continental models
  3. Use better observations and modelling to improve predictions of mountain water supply

    • Predict hydrological cycling and quantify uncertainty in these calculations in ungauged mountain basins
    • Improve the coupling of the sub-surface flow system to the surface / atmosphere system
