The U.S. Geological Survey (USGS) in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District has produced this dataset of groundwater‐level altitudes and groundwater‐level altitude changes in the Chicot, Evangeline, and Jasper aquifers in the Houston‐Galveston region, Texas. This dataset shows current‐year (2018) groundwater‐level altitudes for each aquifer, 5‐year (2013‐18) groundwater‐level changes for each aquifer, long‐term (1990‐2018 and 1977‐2018) groundwater‐level changes for the Chicot and Evangeline aquifers, and long‐term (2000‐2018) groundwater‐level change for the Jasper aquifer. The groundwater‐level measurements...

The U.S. Geological Survey (USGS), in cooperation with the Harris-Galveston Subsidence District and Fort Bend Subsidence District, constructed a finite-difference numerical groundwater-flow model of the northern Gulf Coast aquifer region for 1897 through 2018 using MODFLOW 6 with the Newton formulation solver to simulate groundwater flow and land-surface subsidence. Model parameter estimation and uncertainty analysis were conducted with PEST++ Iterative Ensemble Smoother software. The simulated results are described in the associated U.S. Geological Survey Professional Paper 1877. The model archive provided in this U.S. Geological Survey data release includes all the necessary files to run the MODFLOW 6 model and...
The St. Petersburg Coastal and Marine Science Center is one of three science centers that conduct research within the USGS Coastal and Marine Hazards Research Program. The USGS St. Petersburg Coastal and Marine Science Center has a primary focus of investigating processes related to coastal and marine environments and their societal implications related to natural hazards, resource sustainability, and environmental change.
The U.S. Geological Survey (USGS) in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Lone Star Groundwater Conservation District, and Brazoria County Groundwater Conservation District produced this dataset of groundwater‐level altitudes and groundwater‐level altitude changes in the Chicot and Evangeline aquifers (undifferentiated) and Jasper aquifers in the greater Houston area, Texas. This dataset shows current‐year (2021) groundwater‐level altitudes for each aquifer, 1–year (2020–21), 5‐year (2016–21) groundwater‐level changes for each aquifer, long‐term (1990–2021 and 1977–2021) groundwater‐level changes for the Chicot and Evangeline aquifers (undifferentiated)...

This U.S. Geological Survey (USGS) data release contains the results from the 2017 geomorphic survey of North Fork Eagle Creek, New Mexico. The 2017 geomorphic survey was conducted by the USGS, in cooperation with the Village of Ruidoso, New Mexico, and is the first in a planned series of five annual geomorphic surveys of the stream reach located between the North Fork Eagle Creek near Alto, New Mexico, streamflow-gaging station (USGS site 08387550) and the Eagle Creek below South Fork near Alto, New Mexico, streamflow-gaging station (USGS site 08387600). Specifically, this data release contains the results from 14 cross-section surveys (to include x-y-z coordinates of all cross-section points), the locations of...

This is the USGS California Water Science Center's Catalog and Repository space. This space primarily supports CAWSC science projects by providing a place to organize and publicly release data which cannot fit within the USGS's National Water Information System. The CAWSC mission is to collect, analyze and disseminate impartial hydrologic data and information needed to wisely manage water resources for the people of the United States and the State of California.

This digital dataset contains datasets used to develop the Subsidence Package in CVHM2. Data includes number of delay interbeds per model cell (Neq), equivalent thickness for a delay interbeds (Beq), and the zones used to define subsidence parameters. Beq and Neq are calculated from the database of well logs, which is provided in the parent dataset. Eight zones are used to define subsidence parameters.

The U.S. Geological Survey in cooperation with the Harris-Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District created this dataset that provides water‐level measurements, altitudes, and changes in water-level altitudes in the Chicot, Evangeline, and Jasper aquifers in the Houston‐Galveston region, Texas. The dataset shows current-year (2016-17) water-level altitudes, depth to water, and 1-year (2016-17) water-level changes of select wells screened in the Chicot, Jasper, or Evangeline aquifers. The water‐level measurements in the dataset are built upon and stored in the National Water Information System: Web Interface, groundwater information,...

The Central Valley covers about 20,000 square miles and is one of the most productive agricultural regions in the world. Because the valley is semi-arid, surface-water availability varies substantially. Agricultural demand for irrigation is heavily reliant on surface water and groundwater. In the last few decades, land-use changes and limitations to surface-water availability—including drought and environmental flows—have increased pumping, causing groundwater-level and groundwater-storage declines, renewed subsidence, decreased stream flows, and changes to ecosystems. As these recent trends continue, monitoring, data compilation, and modeling are critical to understanding the dynamics of groundwater use and developing...

GPS data collection: GPS measurements were taken at 24 geodetic monuments during September 27-October 2, 2015. The GPS surveys generally followed established guidelines (Zilkoski and others, 1997), except that the data were processed with single-baseline, rather than multi-baseline, software. GPS measurements were recorded at the monuments on at least 2 different days during 1-hour observation periods. Of the 24 geodetic monuments, 7 were network control stations—DUNE, COCH, DEEP, CAHU, PAIN, C101, and G70; GPS measurements were recorded at these seven stations on 3 additional days during 6.5-hour (or longer) observation periods. InSAR data collection: The data set consists of twenty-four individual interferograms...
