Electrical resistivity tomography (ERT), downhole nuclear magnetic resonance (NMR), and manual permafrost-probe measurements were used to quantify permafrost characteristics along transects within several catchments in interior Alaska in late summer 2016 and 2017. Geophysical sites were chosen to coincide with additional soil, hydrologic, and geochemical measurements adjacent to various low-order streams and tributaries in a mix of burned and unburned watersheds in both silty and rocky environments. Data were collected in support of the Striegl-01 NASA ABoVE project, "Vulnerability of inland waters and the aquatic carbon cycle to changing permafrost and climate across boreal northwestern North America." Additional...

The West Fork of Dall Creek is located ~100km southwest of Coldfoot, AK along the Dalton Highway, south of the Brooks Range. The West Fork of Dall Creek is composed of unburned black spruce forest with a burn scar from the 2004 Dall City Fire. Multi-season, multi-method geophysical data were collected both within the burned and unburned areas. Geophysical techniques used include Nuculear Magnetic Resonance (NMR) and Ground Penetrating Radar (GPR) data. NMR data were collected with a down borehole Dart tool (Vista Clara Inc.). GPR data were collected with a Sensors and Software pulseEKKO pro unit and 100 mHz antennas and a high power (1000V) transmitter. Soil temperature data were collected from the unburned black...
This database contains information on peak flows (floods, hyperconcentrated flows, and debris flows) after wildfire. Data were collected from the scientific literature and the U.S. Geological Survey National Water Information System. These data provide a foundation to assess the upper limits of post-wildfire floods that imperil human lives, infrastructure, and water supplies. Literature citations for studies that the data were sourced from are contained in the file "bibliographyv2.rtf".

This Data Release summarizes measurements of hydraulic and physical properties of soils and ash at sites in the area impacted by the 2017 Thomas Fire, USA. Physical properties include dry bulk density, loss on ignition, and saturated soil water content. Hydraulic properties include field-saturated hydraulic conductivity, sorptivity, Green-Ampt wetting front potential, and soil water retention. Parameters used to represent soil water retention using the van Genuchten approach were also estimated. These measurements provide a foundation to reduce uncertainty of parameters in hydrologic models used to predict water-related hazards, water quality, and water quantity. Note that all methods of data acquisition and processing,...
This data release contains a database reviewing the state of the science for physically based distributed hydrologic model applications for post-fire hydrologic response. The database covers the globe and spans from the years 1998 through the calendar year 2021. The database is part of a larger state of the science review of post-fire hydrologic modeling that examines the scales and geographic/ecohydrologic distribution of model applications, hydrologic response process representation, model parameterization, and model performance metrics.

This data release presents measurements and derived parameters for attributes of bulk density, loss on ignition, soil-water retention, and hydraulic conductivity for a site (adjacent to Richardson Creek) near Hess Creek in interior Alaska, USA. These measurements are useful for hydrologic modeling and predictions of water availability in this region. All methods for sample collection, sample processing, data file column headings, and data annotations are explained in the metadata files.

Rain-gages are critical instrumentation for documenting the rainfall forcing of post-wildfire hydrologic, erosional, and water-quality response. This USGS Data Release presents tipping-bucket rain gage data following two wildfires: the 2000 Cerro Grande Fire near Los Alamos, New Mexico and the 2010 Fourmile Canyon Fire near Boulder, Colorado. The data presented in this USGS Data Release are used for analyses that demonstrate important concepts in precipitation characteristics that relate to temporal and spatial scales. Further information regarding the location and data processing are available in the metadata.
This record contains scientific data characterizing soil properties and hydrologic response to rainfall associated with historic rainfall during September 2013 in the Colorado Front Range, USA. Data include soil depth, soil-hydraulic properties of field-saturated hydraulic conductivity and sorptivity, weathered bedrock hydraulic properties including field-saturated hydraulic conductivity and sorptivity, and soil saturation from automated sensors installed at various depths. Data sites include burned (fire-affected) and unburned (not affected by the 2010 wildfire).

This dataset includes physical and hydraulic properties at selected sites in interior Alaska. Physical properties include dry bulk density, loss on ignition, saturated soil water content, and particle size distribution. Hydraulic properties include field-saturated hydraulic conductivity, soil-water retention data, and parameters used in a common soil-water retention model (van Genuchten model). Volumetric soil-water content profiles with depth are also included. Note that unburned locations are denoted with UB and burned locations are denoted with B.

Wildfire can impact soil-physical and soil-hydraulic properties, with major implications for hydrologic and ecologic response. The durations of these soil impacts are poorly characterized for some forested environments. This dataset sheds light on the first four years of recovery of soil-physical properties of bulk density, loss on ignition (measure of soil organic matter), ground cover, and soil particle size distribution and of soil-hydraulic properties of sorptivity and field-saturated hydraulic conductivity. The dataset also includes a simple infiltration model used to examine infiltration as the sites recover from fire.This is a revision of an existing USGS Data Release to add ground cover data and a model...
This product is a Model Archive for Green-Ampt method infiltration modeling following wildfire in the Boulder Creek watershed, in the Colorado Front Range, USA. The models contained in this archive simulate infiltration and consequent runoff generation through 7 years of recovery following a wildfire in 2010. These simulations provide insight to changes in the timing of runoff generation that have implications for water quantity and quality following wildfire, with direct impacts on water supply.
This Data Release presents soil thermal properties of volumetric specific heat capacity and thermal conductivity for soil samples from six sites in interior Alaska USA. Volumetric specific heat capacity and thermal conductivity data were estimated using a dual needle heat pulse probe. Soil thermal property data were collected across the full spectrum of soil saturations from fully saturated to oven dry. These data are needed for numerical modeling of subsurface thermal conditions for modeling permafrost thaw and associated consequences for water availability in interior Alaska.

The impact of wildfire on water availability is a critical issue in the western United States. Because actual evapotranspiration (ETa) constitutes the largest loss in the terrestrial water budget, it has been suggested that fire-induced ETa reduction is a primary driver of elevated post-fire discharge. Ten gaged watersheds with burns exceeding 5% of their total contributing drainage area were selected from California, Oregon, Montana, Utah, New Mexico, and Colorado. Continuous daily stream gage data were compiled, and 30-meter ETa estimates were calculated with the Operational Simplified Surface Energy Balance (SSEBop) model. Fire-induced ETa shifts were quantified with statistical tests that compared pre and post-fire...
