University of Victoria Aquifer Stress Evaluation
The scope of this project is to derive aquifer-scale estimates of annual volumes for groundwater withdrawal, recharge, and groundwater’s contribution to environmental flows as a means to provide screening level estimates of aquifer-scale stress using the groundwater footprint. The groundwater footprint (GF) is calculated for unconfined aquifers from aquifer-scale, steady-state estimates. For more information see:

Mapping aquifer stress, groundwater recharge, groundwater use, and the contribution of groundwater to environmental flows for unconfined aquifers across British Columbia.

Provenance Text

Withdrawal (W) is estimated based on national, provincial,and municipal scale statistical data, generally following previous methods and then distributed to individual aquifers. Withdrawal is considered a conservative over-estimate that will be replaced by licensed or reported groundwater volumes as this information becomes available. Recharge (R) is estimated from 1. a simple water balance model, HELP , that has been previously used in BC as well as 2. a global hydrologic model, PCR-GLOBWB . HELP modeling used characteristic climatic conditions, hydrogeological properties and water table depths for each aquifer. These estimates are considered suitable for province wide aquifer scale recharge estimation but do not account for local variations in hydrology, geology or topography, neglects three-dimensional processes and time-varying properties. The global hydrologic model includes MODFLOW, has a 10 km grid resolution and is calibrated to global streamflow data and compared to BC streamflow data, but does not use local data. Groundwater contribution to environmental flow needs (E) is estimated from PCR-GLOBWB results using two methods: 1. modeled baseflow and the groundwater presumptive standard and 2. modeled streamflow and the BC EFN policy. The first method appropriately uses hydrogeologic processes such as groundwater discharge as baseflow, but not explicitly consistent with the BC EFN policy . The second method is consistent with the BC EFN policy but does not consider hydrogeologic processes. |
