Inventory of fluvial erosion and debris-flow activity following the 2020 Dolan Fire, California

This data release is a geospatial record of flooding and debris-flow activity following the 2020 Dolan Fire along the central California coast. The postfire hydrologic responses documented here (“Inventory.csv”) are associated with a January 27, 2021, atmospheric river storm that hosted a narrow cold-frontal rain band, which produced intense rainfall over the burned area. Each entry in this record indicates whether no erosion, flooding activity, or debris-flow activity along a given channel reach was apparent in satellite-based imagery and/or during field-based mapping. The “README.txt” file describes the fields for all of the datasets. The “ProcessSteps.txt” file outlines how the data were collected. Additional details and analysis of this dataset are provided in Cavagnaro and others (2025).
