A digital representation of closed depression features overlying and adjacent to New York’s carbonate-bedrock aquifers. Includes closed depressions that are both natural and anthropogenic in origin. The features were derived from a digital contour database obtained from https://topotools.cr.usgs.gov/contour_data.php. The original contour dataset was generated from the National Elevation Dataset (NED) and the National Hydrography Dataset (NHD) in a fully automated process. The process is described in U.S. Geological Survey Scientific Investigations Report 2012–5167.
Dataset provides inputs and model results of a stable isotope-based mixing model for estimating the relative contribution of seasonal recharge sources to the South Rim groundwater flow system, Grand Canyon, Arizona, USA.

A Soil-Water-Balance (SWB) model was developed to estimate annual net infiltration below the root-zone for the Greater Wake County area, North Carolina for the period 1981 through 2019. The model was developed as part of a study to assess groundwater availability in the fractured-rock aquifers underlying Wake County. Curve number, maximum net infiltration rate, and root-zone depth parameters for all land cover classes were adjusted in the SWB model to manually test parameter sensitivity and adjust for best fit. Annual net infiltration estimates from the SWB model were also compared with annual base flow estimates from the PART hydrograph separation technique using the USGS Groundwater Toolbox (Barlow and others,...

A digital representation of the study area boundary adopted for the GIS analyses. The boundary was created by intersecting an index of USGS 1:24,000-scale, 7.5-minute quadrangle maps with data containing selected bedrock geologic units from U.S. Geological Survey Data Series 1052. The final study area boundary covers more than 20,000 square miles, amounting to 38 percent of New York State and transecting 42 counties.
The New York State Departments of Environmental Conservation and Health are concerned about groundwater contamination in the carbonate-bedrock aquifers with the potential to host karst features throughout New York State, especially relating to the unintended introduction of chemical or agricultural contamination into these aquifers. USGS Scientific Investigations Report, SIR 2020-5030 (Kappel and others, 2020), provides local and State regulators and the public the information needed to determine the extent of carbonate bedrock in New York, the associated environmental impacts of karst, and the means to protect New York’s karst water resources. The four geodatabases presented in this data release were compiled...
There is a growing interest in incorporating higher-resolution groundwater modeling within the framework of large-scale land surface models (LSMs), including new processes such as three- dimensional flow, variable soil saturation, and surface water/groundwater interactions. Conversely, complex groundwater models (e.g., the U.S. Geological Survey Groundwater-Flow Model, MODFLOW) often use simpler representations of land surface dynamics (e.g., surface vegetation, evapotranspiration, recharge) and may benefit from higher process fidelity and temporal resolutions in these inputs. This study investigates the potential of improving groundwater representation in LSMs and land surface dynamics in MODFLOW through coupling...
A digital representation of closed depression features overlying and adjacent to New York’s carbonate-bedrock aquifers. Includes closed depressions that are both natural and anthropogenic in origin. The features were derived from Digital Raster Graphic (DRG) images of scanned U.S. Geological Survey 1:24,000-scale topographic maps. A DRG is a scanned image of a U.S. Geological Survey topographic map that can be added as a background layer in a GIS. The closed depressions inventoried using DRGs represent features that were not included in the Digital Contour Database. The features were inventoried as points.
A rain garden and other stormwater control measures (SCM) were installed at Gary City Hall in Gary, Indiana to retain water, increase infiltration and divert stormwater from city sewers. These input data were collected from a rain gage ((USGS site 413611087201301, City Hall Weather Station at Gary, IN.) and five monitoring wells with installed pressure transducers at different locations (see site description). The Episodic Master Recession (EMR) method is applied using these data as the singular input to estimate the amount of groundwater recharge at each of the five sites during the indicated period of time.

As the predicted impacts of climate change are becoming more apparent, natural resource managers are faced with the task of developing climate adaptation plans. These managers need state-of-the-art, scientifically based information upon which to base these management plans and decisions consistently across California and the Great Basin. This project applies historical, current, and projected climate data to a regional water model to examine water availability, biodiversity, and conservation. Analysis of this climate and hydrology data is expected to help managers understand areas in the region and landscape where the effects of climate change are expected to be the most profound. The study also addresses how the...

A rain garden and other stormwater control measures (SCM) were installed at Gary City Hall in Gary, Indiana to retain water, increase infiltration and divert stormwater from city sewers. Input data were collected from a rain gage and five monitoring wells with installed pressure transducers at different locations (BFPK, CH1, CH2, CH3, GWPK; see site description). The Episodic Master Recession or EMR method (Heppner and Nimmo, 2005) is applied using these data as the singular input to estimate the amount of groundwater recharge at each of the five sites during the indicated period of time.

A digital representation of closed depression features overlying and adjacent to New York’s carbonate-bedrock aquifers. Includes closed depressions that are both natural and anthropogenic in origin. The closed depressions were generated from 1-meter and 2-meter resolution LiDAR-derived bare-earth DEMs obtained from the New York State Office of Information Technology Services. At the time of analysis (2017) LiDAR data existed for approximately 65 percent of the study area. The DEMs were processed to identify depressions with an area of at least 4,047 square meters (1-acre) and a depth of at least 1-meter. The closed depressions inventoried using the LiDAR-derived DEMs represent features that were not identified...
This shapefile represents the spatial distribution of mean annual water-budget components, in inches, for the island of Oahu, Hawaii for a projected future-climate condition representative of phase 5 of the Coupled Model Intercomparison Project (CMIP5) Representative Concentration Pathway 8.5 (RCP8.5) 2041-70 scenario climate and 2010 land cover, as described in USGS Professional Paper (PP) 1876 by Izuka and Rotzoll (2023). The water-budget components for each model subarea were computed for the future-climate condition and 2010 land cover using a water-budget model developed by Engott and others (2017). The 2010 land-cover map developed by Engott (2017) was used to define the land-cover conditions and the model...
