Field-saturated hydraulic conductivity time series and sediment accumulations following the 2017 Nuns and Tubbs wildfires, Napa and Sonoma Counties, CA, USA

This dataset comprises repeat surveys of field-saturated hydraulic conductivity and sorptivity following the October 2017 Nuns and Tubbs wildfires as part of an effort to document soil-hydraulic recovery. A summary table includes associated physiographic properties for each site, including: pre-burn vegetation, lithology, soil burn severity, location, soil texture, and associated van Genuchten parameters determined using Carsel and Parrish (1988). Soil-hydraulic properties were calculated using the model of Zhang (1997) and Vandervaere et al. (2000). We separately include the raw cumulative infiltration measurements used for the calculation of soil-hydraulic properties. Lastly, this dataset includes a survey of dry ravel accumulations measured in July 2019 in heavily burned watershed within Mark West Creek Regional Park and Open Space Preserve. Dry ravel accumulations were measured through excavating sediment piles along road cuts and identifying the thickness of post-fire sediment layers. Carsel, R. F., & Parrish, R. S. (1988).
