The Results

To model Alberta’s water resources we used the hydrologic model Soil and Water Assessment Tool (SWAT) in combination with the Sequential Uncertainty Fitting program (SUFI-2) to calibrate, validate, and perform uncertainty analysis based on the available measured river discharge data.

Final results using the observed climate data (as input to the SWAT model)

Long term (1985-2007) average distribution of:

• Precipitation
• Maximum and minimum temperature
• Green water flow (actual and potential evapotranspiration)
• Blue water (water yield plus deep aquifer recharge) and green water storage (soil moisture)
• Deep aquifer recharge

Final results using the CRU gridded climate data (as input to the SWAT model)

Long term (1985-2006) average distribution of:

• Precipitation
• Maximum and minimum temperature
• Green water flow (actual and potential evapotranspiration)
• Blue water (water yield plus deep aquifer recharge) and green water storage (soil moisture)
• Deep aquifer recharge
