This grid represents the hydraulic head distribution in the Wapiti / Belly River hydrostratigraphic unit (HSU). It is a result of a geostatistical model which was constructed using publicly available data from Alberta Environment and Parks' (AEP) Alberta Water Well Information Database (AWWID) and pressure data from drillstem tests from oil and gas wells (see AER/AGS dataset DIG 2018-0005).
The head surface was mapped at a regional scale using many years of data, thus providing a general indication of regional groundwater flow within the unit rather than site-specific values.
