You can use Google Earth as a rough indication of whether your address is at risk of flooding or not.
How ?

- On the preferences under the map ensure that the terrain selector is checked
- Put the hand cursor on the location of your property
- Then look at the altitude measure under the map and move the cursor away from your property in several directions.
- Observing the rise and fall of the altitude can give you some indication of whether you live on high ground (probably ok but not guaranteed) or in a hollow and possibly prone to flooding
You should particularly check the altitude of any nearby rivers.
