|Identifies the flood extent ─ the areas that would be flooded by a given flood (e.g., 200-year/0.5% AEP event) ─ and may show flood elevations and/or depths. These areas are designated as flood hazard areas, usually for planning or regulatory purposes. In these cases, some flood maps show the areas where flood construction levels apply.
|Flood Hazard Map
|Provides information relevant to a given flood or modelled flood scenario, such as flood extent, water depths and/or flow velocity. It shows the intensity and magnitude of the flood.
|Flood Vulnerability Map
|Identifies assets that could be flooded under a given flood. Flood extent or depth information is shown together with assets that are exposed to the flood, such as buildings, emergency facilities, critical infrastructure and schools.
|Flood Risk Map
|Reflects the potential consequences from a given flood event or series of floods. It can incorporate data about population, infrastructure, buildings, and environmental, cultural and other assets that could be affected. Risk is usually expressed in terms of financial impacts. For example, it can show the likely financial losses for a 0.2% AEP flood, or it can show the average loss per year for a range of flood probabilities. When non-monetized impacts are involved, a flood risk map can reflect a relative score to enable comparison of consequences in different areas.
|Emergency Planning Map
|Shows information that could be relevant during a flood emergency. Depending on the scale of the map, this could include dikes, critical infrastructure, disaster response routes, evacuation zones, emergency shelters and other information relevant to inform emergency planning and response.
