Description:
Abstract:
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.
Purpose:
To create a regional hydraulic head map for the Wapiti / Belly River HSU as part of the AGS' Provincial Groundwater Inventory Program.

Data Quality Information:
Logical Consistency Report: Grid cell spacing is 1000 m by 1000 m. Grid cells with no data are assigned the value -9999.
Completeness Report:
The final hydraulic head map covers the extent of the Wapiti / Belly River HSU which was determined based on the lithostratigraphy, hydraulic properties, and the extent of the undivided Wapiti Formation in the west-central plains, and Belly River Group and its equivalents in the southern and east-central plains. Together, these formations were considered as a single hydrostratigraphic unit and the hydrogeological data were grouped to produce this map.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report:
The interpolated surface in the vicinity of water wells may have up to 400 m (occasionally 800 m) of horizontal error due to the positional accuracy of the water wells. Wells in the Alberta Water Well Information Database (AWWID) are frequently placed in the middle of a quarter section (occasionally a section) because their exact location within the quarter section (or section) is not known.
Vertical Positional Accuracy:
Vertical Positional Accuracy Report:

See AER/AGS DIG 2018-0005 (data points) for details on the vertical accuracy of the input data, which is affected by the locational accuracy of the wells.

The following statistics describes the accuracy of the final grid before smoothing:

Root mean squared error = 36.9 m

Mean error = -0.1

Mean standardized error: 0.0074

Root mean square standardized: 1.1

Average standard error: 33.28

Process Description:

Selection criteria for data from AWWID and oil and gas well DSTs, as well as the final data set used for interpolation of this grid are documented in the metadata for AER/AGS DIG 2018-0005.

Step 1 (Modelling the surface): A simple kriging algorithm was used in the ArcMap Geostatistical Analyst extension to interpolate the hydraulic head values and create a grid of the head surface of the Wapiti / Belly River HSU.
