Flood After Fire Infographic Text Version

View the original Flood After Fire infographic.

Did you know wildfires dramatically alter the terrain and increase the risk of floods? Excessive amounts of rainfall can happen throughout the year. And properties directly affected by fires and those located below or downstream of burn areas are most at risk of flooding.

1. During normal conditions, vegetation helps absorb rainwater.
2. But after an intense wildfire, butned vegetation and charred soil form a water repellent layer, blocking water absorption.
3. During the next rainfall, water bounces off of the soil. Higher degrees of land slope speed up water flow and increase flood risk.
4. As a result, properties located below or downstream of the burn areas are at an increased risk for flooding.
   1. Flash floods - Intense rainfall can flood low-lying areas in less than six hours. Flash floods roll boulders, tear out trees and destroy buildings and bridges.
   2. Mudflows - Rivers of liquid and flowing mud are caused by a combination of brush loss and subsequent heavy rains. Rapid snowmelt can also trigger mudflows.
