This map guide explains how to use flood maps. By reference to the scale level of your application, it states the maps that you can use and the best order for your process.
How can you use the maps in this map narrative?
The scale level of your question determines which maps are best to use. The above flowchart lets you choose one of two tracks: are you interested in the flood characteristics of an area or of a specific address?
- An area. If you are looking for the flood characteristics of an area, you start by taking some preparatory steps. First, you consult the flood depth map to see whether the area is prone to flooding and the maximum depth that can occur. If the area is flood-prone, you consult the local flood probability map to find out the probability of the area flooding by 2050. Now you have a basic picture of your area’s flood characteristics. If you know the probability of a certain flood depth, you can proceed to the analysis phase. The map of impact reduction opportunities will give you a basic picture of the options for containing the impact of a flood in your area. Finally, you can use the Risk scan to gain detailed insight at the neighbourhood level into the probability of different flood depths occurring.
- A location or address. If you are looking for the characteristics of a specific address, preparatory steps are not required. You can go directly to My Water Risk Profile . This will give you a detailed picture of the flood depths that can occur at your location and their return frequencies. To gain insight into the options for containing the impact of a flood at your location, you can use the Water Risk Diagram. You will find this under the same tab as My Water Risk Profile .
The Rising water levels map, finally, visualises how climate change is impacting water levels.
