Shortly before the beginning of the 2017–2018 winter rainy season, one of the largest fires
in California (USA) history (Thomas fire) substantially increased the susceptibility of steep …

In the semiarid Southwestern USA, wildfires are commonly followed by runoff-generated
debris flows because wildfires remove vegetation and ground cover, which reduces soil …

Deadly and destructive debris flows often follow wildfire, but understanding of changes in
the hazard potential with time since fire is poor. We develop a simulation‐based framework …

Wildfire‐induced changes to soil and vegetation promote runoff‐generated debris flows in
steep watersheds. Postfire debris flows are most commonly observed in steep watersheds …

Abstract In the southwestern United States, post-fire debris flows commonly initiate during
short bursts of intense rainfall. To date, the frequency of the rainfall rates has not been …

Wildfire alters the hydrologic cycle, with important implications for water supply and hazards
including flooding and debris flows. In this study we use a combination of electrical resistivity …

Modern civilization has no collective experience with possible wide-ranging effects from a
medium-sized asteroid impactor. Currently, modeling efforts that predict initial effects from a …

Predictions of post‐wildfire flooding and debris flows are needed, typically with short lead
times. Measurements of soil‐hydraulic properties necessary for model parameterization are …

Increased wildfire activity in the western United States has exposed regional gaps in our
understanding of postfire debris‐flow generation. To address this problem, we characterized …

Wildfires dramatically alter the hydraulics and root reinforcement of soil on forested
hillslopes, which can promote the generation of debris flows. In the Pacific Northwest, post …
