In March 2015, the U.S. Geological Survey acquired seismic reflection and refraction data along an approximately 2.8-km-long profile across northwest-trending San Andreas Fault splays located at the Dos Palmas Preserve east of Salton Sea. To acquire the reflection and refraction data, we collocated shots and geophones, spaced every 3 m along the profile. We used 933 SercelTM L40A P-wave (40-Hz vertical-component) geophones with a sensitivity of 22.34 volts/meter/second to record 925 P-wave shots. We generated P-wave data using one of two active sources: 400-grain Betsy-SeisgunTM shots at approximately every 90 m and a 3.5-kg sledgehammer and steel plate combination at every 3 m between the seisgun shots. All data...

Groundwater residence times were simulated for the major regional aquifers of the Northern Atlantic Coastal Plain aquifer system from New York to North Carolina using particle tracking in a regional groundwater flow model. Millions of particles were distributed throughout the aquifers of the North Atlantic Coastal Plain in a MODFLOW model with a volume-weighted algorithm, then tracked backwards using MODPATH6 (Pollock, 2012) until termination of their paths at their sources of origin, usually the simulated water table. Particles were tracked under simulated transient hydrologic conditions from the reference time of January 1, 2018 backwards to 1900, then under simulated steady-state conditions prior to 1900 until...

An integrated hydrologic-flow model, called the Central Platte Integrated Hydrologic Model, was constructed using the MODFLOW-One-Water Hydrologic Model code with the Newton solver. This code integrates climate, landscape, surface water, and groundwater-flow processes in a fully coupled approach. This study provided the Central Platte Natural Resources District (CPNRD) with an advanced numerical modeling tool to assist with the update of their Groundwater Management Plan by providing them information on modeled future GW levels under different climate scenarios and management practices. This tool will allow the CPNRD to evaluate other scenarios as management changes in the future. A predevelopment model simulated...

Karst hydrologic systems are important resources in the state of Tennessee both as drinking water resources and as centers for possible biological diversity. These systems are susceptible to contamination due to the inherent connectivity between surface water and groundwater systems in karst systems. A partnership between the U.S. Geological Survey (USGS) and Tennessee Department of Conservation (TDEC) was formed to investigate karst spring systems across the state utilizing fluorescent groundwater tracing, particularly in areas where these resources may be used as drinking water sources. In fall 2021, USGS and TDEC staff identified possible vulnerabilities or complexities that may exist within karst spring systems...

The integrated hydrologic-flow model, called the Osage Nation Integrated Hydrologic Model (ONIHM) was developed to assess water availability in the Osage Nation. This model was developed using the MODFLOW-One Water Hydrologic Model (MF-OWHM) code. The ONIHM was discretized into an orthogonal grid of 276 rows and 289 columns, and each grid cell measured 1,312.34 feet (ft) per side, with eight variably thick vertical layers that represented the alluvial and bedrock aquifers within the study area, including the Vamoosa-Ada aquifer and other minor bedrock aquifers deposited during the Pennsylvanian Period. The ONIHM was delineated into 128 water-balance subregions based on surface watersheds, land cover, and water supply...
