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...

Base waterbody polygon arcs are feature type, source and capture date attributed arcs that make up the boundaries of base waterbody polygons in the Base Features Hydrography geospatial dataset. These arcs were collected from conversion processes of 1:20 000, 1:50 000 and AVI Provincial mapping...

This project generated unique numerical codes at the pixel level to provide wall-to-wall coverage of 128 unique Catchment Structural Units (CSUs) codes based on land use-land cover (LULC), surficial geology, wetlands and slope across the Province. The Provincial CSU layer represents the...

The Single Line Hydrography Network (SLNET) contains all captured single line representations of hydrographic features. In addition, single line representations of polygonal features and single line arbitrary network connectors are in the file.

The Watershed Planning and Advisory Councils (WPAC) boundaries contained in this dataset are an approximate representation of the WPAC planning areas in Alberta. The actual boundary used by individual WPACs may differ from what is contained in this data.These boundaries were derived from the...
