Prepare for Floods

Preparing Canadian residents, businesses and communities for floods

Flood preparedness is a major part of adapting to a changing climate. Community members, business owners, communities, and Canada at large need to prepare for extreme weather and our changing climate.

What can you do to protect yourself?

Understanding floods is important step in preparing for them. Flood events lead to water where it shouldn’t be, and can be the result of one or a combination of the following sources:

1. Fluvial (riverine) flooding – heavy and intense rainfall (often combined with ice jams and extreme snow meltg) leads to overflow of water bodies as water travels from upstream and across the landscape. This can occur over several hours or days, or can be immediate and unpredictable (flash flooding).

2. Pluvial flooding – heavy and intense rainfall that occurs away from a waterbody. This is common in flatter areas away from waterbodies as heavy rain ponds on saturated land, and in urban areas where there is insufficient drainage as we use land for parking lots and buildings. Urban flooding is made worse when water and sewer systems are overwhelmed and water has nowhere to go and ends up in basements.

3. Coastal flooding or storm surge – severe coastal weather events can cause heavy rains and changes in atmospheric pressure, pushing seawater onto the coastline, flooding large areas. Flooding can even been seen further inland as seawater is pushed into freshwater outlets, overflowing their banks.
