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...

Compilation of In Situ Stress Data from Alberta and Northeastern British Columbia (tabular data, tab delimited)

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

This GIS dataset depicts the drift thickness in the Edmonton-Calgary corridor based on water-well litholog data and bedrock outcrop locations. We used well data from an internal Edmonton-Calgary corridor geological mapping database. This thickness map was generated to assist in building a geological model for the region. The sediment thickness was generated by subtracting the bedrock topography surface from the 60 m Shuttle Radar Topography Mission v. 2 digital elevation model.

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...
