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 series of 1:250 000 scale colour maps covers the provincial extent of Alberta and is comprised of 50 maps that are individually named using the National Topographic System (NTS) map sheet identifier. These maps display: Alberta Township System (ATS), contours (50m intervals), major hydrographic features, municipalities, major roads, railways, and select geo-administrative features (parks, reserves, etc.).

Description

This GIS dataset is part of a digital compilation of the bedrock geology of NTS areas 72E, 72L, 73D, and 73E. It is one of the datasets used to produce Alberta Geological Survey (AGS) Maps 567, 568, 569, and 570. This dataset represents the compilation of existing geological maps and original geological mapping by AGS staff. Mapping included field observations and creating three-dimensional models of subsurface stratigraphy based on the interpretation of geophysical logs from oil and gas wells. Each three-dimensional formation surface was projected to a model of the bedrock surface, and the intersection formed the first approximation of the position of the geological contact at the base of the surficial deposits. We adjusted these preliminary contacts to honour outcrop data and the interpretation of the bedrock unit immediately below surficial deposits in individual wells. The data were created in file geodatabase format and output for public distribution in shapefile format. AGS...

Inventory of tiny cryptanthe (Cryptantha minima) and small-flowered sand verbena (Tripterocalyx micranthus) in Alberta

Description

Alberta Sustainable and Resource Development initiated an inventory of small-flowered sand verbena and tiny cryptanthe in southern Alberta in July 2007, in order to obtain additional information on their populations, abundance and distribution. Priority areas for this survey included the Bow River populations, north of Medicine Hat, and near McNeill. Prioritization of these areas occurred because of the absence of other survey efforts covering these known populations of tiny cryptanthe and/or sand verbena.
