Short summary

A HydroGeoSphere model which represents surface and groundwater is used to assess trends from 2002–2019 in water resources in Alberta, Canada and the driving factors behind these changes. Satellite-derived gravity data is compared to HydroGeoSphere model results; a strong correlation is identified. Components of water storage are assessed, namely groundwater, soil moisture, surface water, and snow. Fluctuations in water storage in Southern Alberta are linked to global climatic indices.
