Cross section showing the water table varying with surface topography as well as a perched water table Cross-section of a hillslope depicting the vadose zone, capillary fringe, water table, and the phreatic or saturated zone. (Source: United States Geological Survey.) The water table is the upper surface of the zone of saturation.
The Leduc Formation is a stratigraphic unit of Late Devonian age in the Western Canada Sedimentary Basin. [3] It takes its name from the city of Leduc, and it was formally described from the B.A. Pyrz No. 1 well in central Alberta, between the depths of 1,623.7 m (5,327 ft) and 1,807.5 m (5,930 ft), by Imperial Oil Limited in 1950.
Mine at the Athabasca Oil Sands. According to the Alberta Energy and Utilities Board (EUB, now known as the Alberta Energy Regulator, the AER), Alberta's oil sands areas contain an ultimately recoverable crude bitumen resource of 50 billion cubic metres (315 billion barrels), with remaining established reserves of almost 28 billion cubic metres (174 billion barrels) at year-end 2004.
The formation is exposed at the surface along a trend that extends from Calgary to west of Edmonton. Good outcrops can be seen in the eastern reaches of the foothills, and along the Bow River in and around Calgary (for example at Paskapoo Slopes), the Red Deer River near Red Deer, the North Saskatchewan River west of Edmonton, and the Athabasca ...
According to the US Geological Survey, there are 5 steps to manual watershed delineation: [6] Find the point of interest along a stream on the map. This is the "watershed outlet" or "pour point." Imagine or draw surface water flow lines that point downhill perpendicular to the topographic contours (this is the steepest direction).
The McMurray Formation is a stratigraphic unit of Early Cretaceous age (late Barremian to Aptian stage) of the Western Canada Sedimentary Basin in northeastern Alberta. [4] It takes the name from Fort McMurray and was first described from outcrops along the banks of the Athabasca River 5 kilometres (3.1 mi) north of Fort McMurray by F.H. McLearn in 1917. [3]
A geologic map or geological map is a special-purpose map made to show various geological features. Rock units or geologic strata are shown by color or symbols. Bedding planes and structural features such as faults , folds , are shown with strike and dip or trend and plunge symbols which give three-dimensional orientations features.
Digital geologic mapping is the process by which geological features are observed, analyzed, and recorded in the field and displayed in real-time on a computer or personal digital assistant (PDA). The primary function of this emerging technology is to produce spatially referenced geologic maps that can be utilized and updated while conducting ...
