A digital grid of the top of the Empress Formation where present, or the topography of the surrounding landscape, where the formation is absent. This includes the units 1 to 3 of the Empress Formation in buried valleys, as well as undifferentiated Empress interfluve sediments resting on the bedrock surface between buried valleys. The unit is originally modelled from borehole data and adjusted to the bedrock surface, the surfaces of units 1, 2, 3 and interfluve units of the Empress Formation, and the present-day land surface. The grid is generated at a 250 metre cell-size resolution, based on 2003 information.

This GIS dataset depicts an estimate of average annual groundwater recharge in the Edmonton-Calgary corridor based on hydrological water budget analysis using climate and hydrometric data from Environment Canada, the Water Survey of Canada, and Alberta Environment and Sustainable Resource Development. This average annual groundwater recharge grid was generated to assist in building steady-state numerical groundwater flow models for large regions within the Edmonton-Calgary Corridor.

This grid dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the structure top of the Paskapoo Formation, which is the bedrock surface in the Sylvan Lake sub-basin. The Paskapoo Formation is a highly heterogeneous system. To satisfy the needs of a groundwater flow model, internal characterization of rock properties was necessary to partition the formation into three distinct geological domains. The Upper Composite Slice is the uppermost of these three domains. Alberta Geological Survey (AGS) Open File Report 2014-10 includes a full description of the process used to produce this structure grid.

This grid dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the structure top of the Paskapoo Formation - Lower Composite Slice of the Sylvan Lake sub-basin. The Paskapoo Formation is a highly heterogeneous system. To satisfy the needs of a groundwater flow model, internal characterization of rock properties was necessary to partition the formation into three distinct geological domains. The Lower Composite Slice is the lowest of these three domains.

This dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the structure top of the Wapiti Formation in the Sylvan Lake sub-basin. Bedrock units included in the Sylvan Lake sub-basin model are derived from the Geological Framework of Alberta, a regional geological model of the province. The Top of Wapiti Formation (or Battle Formation base), provided by the Geological Framework of Alberta, was clipped to the Sylvan Lake sub-basin model domain for integration into a multi-layer hydrostratigraphic model. This dataset supplements Alberta Geological Survey (AGS) Open File Report 2014-10, which includes a full description of the methodology used to produce this grid.

This dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. It represents the structure top of hydrostratigraphic unit (HSU) S1, which contains coarse-grained material lying directly on bedrock and constrained to paleovalleys in the Neogene-Quaternary succession of the Sylvan Lake sub-basin. This dataset supplements Alberta Geological Survey (AGS) Open File Report 2014-10, which includes a full description of steps taken to produce the structure grid.

This polygon dataset is part of the three-dimensional (3-D) hydrostratigraphic model of the Sylvan Lake sub-basin in the Edmonton-Calgary Corridor, central Alberta. This dataset provides the areal distribution of greater than or equal to 0.60 net-to-gross sandstone values for the Paskapoo Formation - Middle Composite Slice, defined by an analysis of normalized oil and gas well digital gamma-ray logs to produce discrete slices of net-to-gross sandstone distribution within the Paskapoo Formation. The zonated Paskapoo Formation - Middle Composite Slice is in ESRI shapefile format for input into a groundwater flow model. This dataset supplements Alberta Geological Survey (AGS) Open File Report 2014-10, which includes a full description of the steps taken to produce the dataset.
