- •
The impact of ash wettability on soil erosion was studied after a prescribed burn.
- •
Splash erosion was three times higher in hydrophobic than in wettable ash layers.
- •
Runoff rate on hydrophobic ash was higher than in wettable areas.
- •
Runoff rate on hydrophobic ash increased inversely to the depth of the ash layer.
- •
Low runoff rates on wettable ash reduced the connectivity of sediments and water.
