The Effects of Forest Fires on Runoff Rates: The Role of Duff Removal and Surface Sealing by Vegetative Ash, Western Montana
Increases in runoff and erosion following a forest fire are often attributed to the removal of the surface duff and litter, the formation water repellent soils, and surface sealing. There has been considerable work on the influence of water repellency on post-fire runoff, however few studies have …
