Description

Flood maps are created by combining hydraulic model results with high-accuracy ground information. Field surveys and LiDAR remote sensing are used to collect river and floodplain elevations, channel cross section data, bridge and culvert information, and flood berm details. A hydrology assessment using recorded and historic flow measurements is typically used to estimate river flows for a wide range of possible open water floods with different chances of occurring each year. When appropriate, an ice jam frequency analysis is undertaken. All this information is used to build a hydraulic model of a river system, which is calibrated using highwater marks and aerial imagery from past floods to ensure that results for the different flood flows being mapped are reasonable. Flood inundation maps show areas at risk for different sized floods, including ice jam floods in some communities. These maps also identify areas that could be flooded if berms or other flood control structures fail and...

Description

This digital dataset is the compilation of an analysis of the in situ stress regime in several regions of Alberta and northeastern British Columbia conducted by Dr. Sebastian Bell under a contract with the Alberta Geological Survey from 1999 to 2004. The dataset includes both new and previously published estimates for vertical stress gradients, minimum horizontal stress gradients, and stress orientation. Understanding the state of stress in the subsurface has always been important in the development of energy resources. The recent development of unconventional oil sand and low permeability hydrocarbon deposits, waste fluid disposal, greenhouse gas sequestration, and potential geothermal energy extraction all require knowledge of the state of stress to operate safely and economically. A lack of understanding of the state of stress in a given project area has the potential to negatively affect the economics of such projects and may expose operators to increased liabilities.

Description

The dataset contains the results of analyses of surface water samples collected by AGS in the summer of 1999. Three lakes, three creeks, one stream and two rivers were sampled as part of a water sampling program carried out by AGS in the Athabasca Oil Sands in-situ area of Alberta. This area extends from approximately 55.34 degrees north latitude to 55.96 degrees north latitude, and 110.5 degrees west longitude to 111.8 degrees west longitude. The datum is NAD83. The dataset contains information on laboratory measured pH and conductivity, major, minor and trace element concentrations, as well as stable isotope ratio values of oxygen and hydrogen. AGS staff collected the samples using a discrete sampling method. The sample bottle was dipped into the surface water body and partially filled with water, rinsed and the water was discarded. The bottle was then filled and capped. The sample was subsequently filtered on site using a 0.45 micron filter. A sample was acidified for minor and...

Description

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.

Description

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 - Lower 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 - Lower 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.
