Heat can be used a tracer for monitoring seepage rates within stream channels. To estimate seepage using temperature, the diel amplitude and attenuation of temperature at several depths below the streambed must be monitored, as well as the frequency and duration of streamflow in a channel (Narranjo and Smith, 2016). Special subsurface temperature rods (TRODS) were developed to address these most of these needs (Narranjo and Turcotte, 2015). A TROD consists of discrete temperature iButton sensors within a .75 inch (in) diameter 1 meter (m) long sealed, water-proof PVC pipe to prevent water damage to the sensors. A TROD is installed into stream channel sediments and measures surface water and sediment temperatures...

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...

The San Antonio Creek Valley watershed (SACVW) is located in western Santa Barbara County about 15 miles (mi) south of Santa Maria, California and 55 mi north of Santa Barbara, California. The SACVW, is about 140 square miles and encompasses the San Antonio Creek Valley groundwater basin; From the late 1800s, groundwater has been the primary source of water for agricultural, military, municipal, and domestic uses. Groundwater withdrawal from pumping has exceeded the amount of water replenishing the basin, causing groundwater declines of more than 150 feet in parts of the valley between 1943 and 2017, and reducing base flow in San Antonio Creek at the western end of the SACVW. Agricultural water use (primarily for...

During 2015-17, the U.S. Geological Survey (USGS), in cooperation with the U.S. Department of Agriculture Forest Service (USDA FS), carried out a study to characterize the hydrology and water chemistry in the Rock Creek and Cumberland River areas of the Daniel Boone National Forest. The study areas were historically mined for coal and have since been the focus of remediation efforts. The study examined the contributions of tributaries and gains/losses in both areas, and continuous water-quality and base flow estimates at Rock Creek, so the USDA FS can thoroughly evaluate the current conditions and move forward with well-informed remediation efforts.
Infiltrometers are devices used to measure the infiltration rates of water into soils or porous media (Bouwer, 1986). Cylinder infiltrometers are generally constructed from metal shaped into cylinders which are driven into the ground and flooded with water. The rate at which water infiltrates into the ground is measured until the rate of infiltration is constant to capture unsaturated infiltration rates and beyond steady state to measure saturated infiltration rates and conductivity (Bouwer, 1986). Infiltrometers are typically employed to measure the rate of infiltration on inundated soils such as surface irrigation, seepage from surface water such as streams or reservoirs, or infiltration basins for groundwater...

Soil data were collected from catchments of USGS edge-of-field (EOF) monitoring sites in Great Lakes Restoration Initiative (GLRI) priority watersheds. As part of this release, soil data from 2016 through 2019 are provided from 14 sites spanning 5 Great Lake States (Wisconsin, Michigan, Ohio, Indiana, and New York). The data collected are from private farms representing a variety of agronomic systems, landscapes settings, soil types, and climate regimes. These data can be used to investigate relationships among microbial properties (e.g. soil microbial biomass, activity, diversity, and enzymes), general soil structure (e.g. bulk density, soil aggregate structure, soil water holding capacity, soil texture, and infiltration...

This data release contains code for computing the filtering properties of cyclical infiltration in a layered vadose zone in Central Valley, California. The code for computing the filtering is described in a manuscript that is under review at Vadose Zone Journal. The updated data contained in this data release are the code to compute the filtering properties of the vadose zone. This code was developed in 2018. The code uses existing data as inputs. The inputs are from a groundwater flow model for Central Valley, California, described by Faunt et al. (2009), and from a soil texture model described by Faunt et al. (2010). The inputs from Faunt et al. (2009) and Faunt et al. (2010) were released in those years and are...
