Flood studies include detailed engineering reports and flood maps. The engineering reports are typically technical in nature and document the data, assumptions, and results of the hydrologic and hydraulic analyses required to create flood maps. Flood maps are created by combining hydraulic model results for different sized floods with high-accuracy ground information. Flood maps identify where water will flow during a flood, and what land could be flooded during different sized floods. Most flood maps focus on floods caused by high river flows when water escapes the river channel, most often experienced in spring or following summer rainstorms, but they can also show areas at risk from ice jam floods or document the extent of historic floods.Flood inundation maps show areas at risk for different sized floods, including ice jam floods in some communities, and identify areas protected by flood berms. Because they map a wide range of floods, they are most often used for emergency response planning and to inform local infrastructure design. Flood hazard maps define floodway and flood fringe areas for the 1:100 design flood and are typically used by communities for planning or to help make local land use and development decisions. The floodway is the portion of the flood hazard area where flows are deepest, fastest and most destructive. The flood fringe is the portion of the flood hazard area outside of the floodway, where flood water is generally shallower and flows slower than in the floodway. High hazard flood fringe is the area within the flood fringe with deeper or faster moving water than the rest of the flood fringe. Protected flood fringe identifies areas that could be flooded if dedicated flood berms fail or do not work as designed during the 1:100 design flood. Flood hazard maps define floodway and flood fringe areas for the 1:100 design flood and are typically used by communities for planning or to help make local land use and development decisions. Flood hazard maps can also illustrate additional information for communities to consider, including incremental areas at risk for floods larger than the 1:100 design flood, such as the 1:200 and 1:500 floods.Visit www.floodhazard.alberta.ca for more information about the Flood Hazard Identification Program. The website includes different sections for final flood studies and for draft flood studies. Flood maps can be viewed directly using the Flood Awareness Map Application at https://floods.alberta.ca/. The Alberta Flood Mapping GIS dataset is updated when new information is available or existing information changes. therefore, the Government of Alberta assumes no responsibility for discrepancies at the time of use. Users should check https://geodiscover.alberta.ca/ to verify they have the most recent version of the Alberta Flood Mapping GIS dataset.

The Canada Flood Map inventory shows areas in Canada where a copy of a flood hazard map has been collected by Natural Resources Canada (NRCan). The inventory does not display flood zones or extents, but provides information on how to access these flood hazard maps. Depending on the license and availability status to the public, there may be links for download, along with reference information to the original source and/or data owner. NRCan collaborates with provincial and territorial governments to gather flood hazard maps from provinces, territories, municipalities, and other agencies responsible for flood mapping. The inventory is regularly updated to improve its completeness and accuracy. Disclaimer: The Canada Flood Map (CFM) does not include every flood hazard map in Canada and may be incomplete or contain inaccuracies. It should not be relied upon as the official source of flood mapping information. Furthermore, if a map appears to be missing, this does not necessarily mean that the area has never been mapped. For the official version of a map, updated information, or confirmation of applicable regulations, please contact the local authority responsible for flood mapping.Note: Data and maps in the Inventory can be made available upon request to federal and contributing partners.

The Flood Hazard Map Index provides awareness of the areas at risk of flooding and support for improved decision making for activities and development in flood prone areas. Scanned, black and white images of New Brunswick Flood Risk Map Sheets.

This national map of flood susceptibility or flood prone areas is based on patterns of historic flood events as predicted by an ensemble machine learning model.The recommended use is national, provincial or regional scale and can be used as a guide for identifying areas for further investigation. The Flood Susceptibility Index (FSI) Dataset, while processed and available at 30m cell size, is not recommended for use at the pixel or street level, given the uncertainty in the modelling process and the variability of results as discussed in https://www.mdpi.com/2673-4931/25/1/18 .For additional details on the methods, tests, models and datasets used to generate this data layer, please see https://geoscan.nrcan.gc.ca/starweb/geoscan/servlet.starweb?path=geoscan/fulle.web&search1=R=329493

This series of historic flood susceptibility maps comes from an XGBboost machine learning model trained on major floods from 2005 to 2023. The trained model is then run for each year from 2000 to 2023, including unique temporal characteristics of temperature, precipitation, land use land cover and Normalized Difference Vegetation Index (NDVI), to predict the flood susceptibility of any given year.Parent Collection:- **[Collection - Flood Susceptibility Mapping- Cartographic Product Collection](https://open.canada.ca/data/en/dataset/1074f781-85d3-4c86-86cb-fd1c339197dc)**
