Water, sediment supply reqs—post-wildfire debris flows in western U.S.
Water, sediment supply reqs—post-wildfire debris flows in western U.S.We sometimes fall back on an implicit model that post-wildfire debris flows are only triggered once a certain level of saturation or rainfall is reached, and that the sediment supply is soon exhausted and future flows are unlikely until it recharges.
