These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This data set represents potentiometric surface contours for the Minnekahta aquifer, Black Hills, South Dakota.
The California Coast Range are an area with a long-lived deformation history which includes modern, ongoing right lateral strike slip faulting. Large strike slip faults in the region include the San Andreas fault, the Maacama fault, the Bartlett Springs fault among many others. In areas where strike slip fault geometry changes, either in restraining or releasing bends, vertical motion may occur in response to dominant right-lateral deformation. Channel steepness and chi data may be used to identify areas of recent uplift where the bedrock hardness and local precipitation gradients are known. This dataset provides a map of channel steepness and chi and was generated with Land Surface Dynamics Topography Tools software...
The Hamilton Wetland Restoration Project (HWRP) is a joint venture between the US Army Corps of Engineers (USACE; San Francisco District) and the California State Coastal Conservancy. The site is located on the property of the former Hamilton Army Airfield in Novato, California, along the western edge of San Pablo Bay, which is part of northern San Francisco Bay. The initial stages of wetland restoration, which included dredged sediment reuse, took place during 2009–2011. From 2011 until April 2014, the site was maintained as partially flooded through a temporary one-way culvert that allowed bay water onto the site. On April 25th, 2014, the outboard levee towards the north-eastern corner of the site was breached...

A generic, three-dimensional finite-difference model, MODFLOW-2005 (version 1.12.00) and MODPATH-6 (version 6.0.01), was created to better understand the amount of vertical flow and cross-contamination of trichloroethene (TCE) that may be occurring in discontinued extraction wells under current (2018-19) ambient-flow conditions at site 25 of the Edwards Air Force Base, California. The wells are long-screened (100-ft long), contain a surrounding sandpack, and have not been pumped for approximately 10 years. The groundwater flow model utilized multiple observations made from the field measurements of flow and transport to conceptualize, calculate, and simulate in-well flow, and flow in the sand pack. The model was...

The Geneva Industries/Fuhrmann Energy Superfund Site (hereinafter referred to as "the Site") in southeastern Houston, Texas was historically used as a site for petroleum exploration and petrochemical production and is currently (2024) inactive. Previous remedies to clean up the contaminated site included the excavation and off-site disposal of polychlorinated biphenyl (PCB)-contaminated soils, capping the Site and surrounding it with a perimeter slurry wall to contain remaining constituents in the soil and groundwater, the recovery and treatment of trichloroethylene (TCE)-contaminated groundwater, and institutional controls (U.S. Environmental Protection Agency [EPA], 2018). A conceptual site model (CSM) does not...
Samples of silicified wood remnants from 8 trees were collected under research permit YELL-SCI-8030 on June 17, 2023, and on September 19, 2023 adjacent to Artemisia Geyser in the Upper Geyser Basin of Yellowstone National Park. Samples were collected for radiocarbon (14C) dating of the wood to determine when the trees grew. Trees do not grow on active geyser mounds (Hurwitz and others, 2020, 2024) and therefore, trees grew around Artemisia Geyser during a protracted period of eruption quiescence. The study of silicified trees at Artemisia Geyser follows similar studies at Old Faithful Geyser in the Upper Geyser Basin (Hurwitz and others, 2020) and at Steamboat Geyser in Norris Geyser Basin (Hurwitz and others,...
A series of field measurements of surface water velocity derived from video and Doppler velocity radar collected by small unoccupied aircraft systems (sUAS) and portable sensors were collected at seven locations in Colorado, USA, during the summer of 2023. The measurements were utilized to compute surface velocity and discharge using the Probability Concept, Large-Scale Particle Image Velocimetry (LSPIV), and Space-Time Image Velocimetry (STIV) methods. This data release includes the original videos, radar spectra, and ancillary data necessary to produce the surface water velocity and streamflow results. Data are grouped into sections (child items) based on the data type and purpose: Ancillary Scripts: this child...

This data release (DR) is the update of the U.S. Geological Survey - ScienceBase data release Bera (2023), with the processed data for the period October 1, 2021, through September 30, 2022. This data release describes the watershed data management (WDM) database SC22.WDM. The precipitation data are collected from a tipping-bucket rain-gage network and the hydrologic data (stage and discharge) are collected at USGS streamflow-gaging stations in and around Salt Creek watershed in DuPage County, Illinois, as described in Bera (2014). Hourly precipitation and hydrologic data for the period October 1, 2021, through September 30, 2022, are processed following the guidelines described in Bera (2014) and Murphy and Ishii...
Monroe County, in southeastern West Virginia, hosts world-class karst within carbonate units of Mississippian and Ordovician age. There are at least 412 known caves in the county. Location data for these caves were collected from the West Virginia Speleological Survey (WVASS) Bulletin 22 (Dasher, 2019). Point features were created in ArcGIS Pro for each cave location and were used to make a point density raster. This raster displays the number of cave points per square kilometer.

This data package documents selected special conditions affecting the magnitude of peak flows at streamgages in Alaska. The data consist of a table of special conditions for selected peak flows and a table of data sources. This dataset resolves ambiguity introduced by historical variations in USGS National Water Information System (NWIS; https://doi.org/10.5066/F7P55KJN) peak-flow code assignment practices or inherent in defining multiple possible conditions for a single code. For peak flows assigned a code 3 or 9 in the NWIS peak-flow database, the special conditions forming the basis for code assignment were (1) snowmelt or (2) a sudden release of water. Sudden releases of water included glacier dammed lake outburst,...
