Climate Change and Groundwater: A Modelling Approach for Identifying Impacts and Resource Sustainability in the Central Interior of BC
A case study of an unconfined aquifer in the Grand Forks valley in south-central BC was used to
develop methodology for linking climate models, hydrologic models, and groundwater models to
investigate future impacts of climate change on groundwater resources.
The aquifer is 34 km2,
located in a semi-arid climate, and comprised of heterogeneous glaciofluvial / glaciolacustrine
sediments that partially infill steep and variable bedrock topography in a mountainous valley.
The bedrock surface of the Grand Forks valley was eroded by glacial processes during the
Wisconsin glaciation, and by pre-glacial fluvial erosion. The valley shape was modelled using
profile extrapolation, constrained by well lithologs, and geostatistical interpolation. Total
sediment thickness was estimated. The hydrostratigraphic units were modelled in threediemensions
from standardized, reclassified, and interpreted well borehole lithologs. Solid
models were constructed. A stochastic hydrostratigraphic model was also generated and
compared to the layered hydrostratigraphic model.
