Postfire debris-flow volumes and their associated observation, location, and volume sources This table contains measured and modeled postfire debris flow volumes alongside the associated sources for debris flow documentation, locations, and volumes. We conducted a search of scientific literature and news media reports to find documentation of debris flows that may have followed all wildfires greater than 100 square kilometers that occurred between 1984 and 2021 in California. The wildfires listed are all the fires we found that had documented postfire debris flows. Some fires had field-measurements of debris flow volume. Where field-measurements of volume did not exist, we used model data on postfire debris-flow likelihood and volume from U.S. Geological Survey Emergency Assessment of Post-Fire Debris-Flow...

Postfire erosion estimates for large California wildfires that occurred between 1984 and 2021 This data release presents a compilation of postfire sediment mobilization data from wildfires greater than 100 km2 that occurred in California or regions of southern Oregon that drain to the California coast between 1984 and 2021. This compilation includes three sources of sediment mobilization data: hillslope erosion modeled using the Water Erosion Prediction Project (WEPP) postfire erosion model (Lew and others, 2022 and references therein), field-derived measurements of postfire debris flow volumes, and modeled debris flow volumes produced using the U.S. Geological Survey Emergency Postfire Debris Flow Hazard Assessments (https://landslides.usgs.gov/hazards/postfire_debrisflow/). This dataset supports analysis... Categories: Data; Tags: CMHRP, Coastal and Marine Hazards and Resources Program, Geomorphology, Land Use Change, PCMSC, All tags...
Geographic data defining watersheds less than 45 square kilometers burned in all California wildfires greater than 100 square kilometers, 1984—2021 This table contains geographic information defining watersheds that were burned in large wildfires (greater than 100 square kilometers) that occurred in California or California-draining regions (i.e., upper Klamath watershed) between the years 1984 and 2021. Each wildfire was broken into tens to thousands of small watersheds, and each row of this table contains geographic information defining a single watershed.

Summary by wildfire of all postfire erosion modeled estimates and field-based observation for large fires 1984-2021 These data show all the postfire erosion results affiliated with this data release summed by wildfire and attached to a polygon of each fire perimeter, as defined by Monitoring Trends in Burn Severity (MTBS). The results are shown as attributes for each polygon of wildfire perimeter. Some of the original MTBS data (name, ignition date, and ID) were preserved to allow for joining to other MTBS data. Results include WEPP modeling results of hillslope and channel erosion, a sum of postfire debris flow modeling results and field-based measurements, and a few derived results such as total sediment and total yield (mass per area).

Model estimates of the probability and volume of debris flows that may be produced by a storm following recent wildfire; re-release of ten wildfires across California, 1997—2015 These data show model estimates of debris flow likelihood and volume that may be produced by a storm in a recently burned landscape. The scientific methods used by the U.S. Geological Survey Emergency Assessment of Post-Fire Debris-Flow Hazards were changed following 2015, and these shapefiles are a re-release of ten fires that occurred between 1997 and 2015 fires, using the updated methods. These ten fires were re-run to provide estimates of debris flow volumes as post-fire debris flows were documented but no field measurements were published.

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
