Modeled surface soil moisture of three California wildfire areas from 2016 - 2017 Modeled surface soil moisture of three California wildfire areas from 2016 - 2017
This data release includes raster images of pre- and post-wildfire surface soil moisture modeled from Landsat Thermal-infrared and Sentinel-1A synthetic aperture radar for three fires that took place in the state of California (USA) between 2016 and 2017 and associated unburned, control locations for each wildfire. The model was trained and validated using In situ soil moisture data...
Modeling data for landscape connectivity and wildlife access to water across an international border Modeling data for landscape connectivity and wildlife access to water across an international border
We used a landscape connectivity model to investigate the effects of barriers on wildlife access to water within the Lower Rio Grande Valley in southern Texas (USA). We used a modified omnidirectional connectivity model to compare wildlife access to the river across three border barrier scenarios: 1) a landscape without border barriers; 2) a landscape with the existing barrier system as...
MODFLOW 6 and MODPATH models used to simulate the steady-state hydrologic system surrounding the Zuñi Salt Lake, west-central New Mexico MODFLOW 6 and MODPATH models used to simulate the steady-state hydrologic system surrounding the Zuñi Salt Lake, west-central New Mexico
The terminal Zuñi Salt Lake is in a broad, low relief volcanic crater, or maar, in west-central New Mexico and contains hypersaline water that has long been used by Native Americans for religious purposes and the collection of salt. In 1986, ownership of the Zuñi Salt Lake was transferred to the Zuni Tribe of the Zuni Reservation, New Mexico, which has managed it as a natural and...
MODFLOW 6 Datasets for a Groundwater-flow Model in the Saco River Basin, New Hampshire and Maine MODFLOW 6 Datasets for a Groundwater-flow Model in the Saco River Basin, New Hampshire and Maine
A MODFLOW 6 groundwater model for the Wards Brook aquifer in New Hampshire and Maine was developed to understand the effects of groundwater withdrawals for historical and potential future conditions. The model assesses how groundwater withdrawals, including for bottled water, affect base flows from Wards Brook, groundwater levels, and pond levels under different scenarios. Model runs...
MODFLOW 6 groundwater flow models and supporting data for evaluation of stream capture related to groundwater pumping, middle Humboldt River Basin, Nevada MODFLOW 6 groundwater flow models and supporting data for evaluation of stream capture related to groundwater pumping, middle Humboldt River Basin, Nevada
A calibrated numerical groundwater flow model was developed for the middle Humboldt River Basin (MHRB), Nevada, to estimate stream capture from groundwater pumping over time. Stream capture was estimated for water years (WY) 1961–2015 with pumping from that period, and the model was then used to predict future stream capture based on constant non-mining pumping rates in WY 2015. The...
MODFLOW 6 model used to evaluate groundwater/surface-water interactions in the Mobile Bay, AL MODFLOW 6 model used to evaluate groundwater/surface-water interactions in the Mobile Bay, AL
This model archive contains the model files for the Mobile Bay groundwater-flow model documented in the U.S. Geological Survey Scientific Investigations Report 2026–5125. The Mobile Bay model simulates transient groundwater flow in Mobile Bay and surrounding coastal areas of Alabama and Mississippi from 2008 through 2015. The primary goal of the model was to determine how changes in...
MODFLOW-6 groundwater flow model and model scenarios of the Ogallala and Arikaree aquifers, Rosebud Sioux Tribe national areas, South Dakota MODFLOW-6 groundwater flow model and model scenarios of the Ogallala and Arikaree aquifers, Rosebud Sioux Tribe national areas, South Dakota
The Ogallala and Arikaree aquifers are important water resources for the Rosebud Sioux Tribe and are used extensively for irrigation and domestic water supplies. Drought or increased withdrawals from the Ogallala and Arikaree aquifers in the Rosebud Sioux Tribal lands potentially affect water levels in these aquifers. MODFLOW-6 (version 6.6.0) groundwater flow models of the Ogallala and...
MODFLOW-NWT and MODPATH6 files used for groundwater-flow simulation and pathline analyses in the vicinity of the Coakley Landfill Superfund site, Rockingham County, New Hampshire MODFLOW-NWT and MODPATH6 files used for groundwater-flow simulation and pathline analyses in the vicinity of the Coakley Landfill Superfund site, Rockingham County, New Hampshire
A MODFLOW-NWT groundwater-flow model of the Coakley Landfill (CL) area in southeast New Hampshire was constructed from a previously published hydrologic model of the southeast New Hampshire region (https://doi.org/10.5066/P909PUIP). The CL model was used to evaluate groundwater-flow patterns and advective transport pathways from the CL as a proxy to solute transport of per- and...
MODFLOW-OWHM Used to Evaluate Groundwater Sustainability Goals of the Central Valley, California MODFLOW-OWHM Used to Evaluate Groundwater Sustainability Goals of the Central Valley, California
The Central Valley Hydrologic Model version 2 (CVHM2) simulation period has been extended to the year 2100 to assess the feasibility of groundwater level sustainability goals established under California's Sustainable Groundwater Management Act (SGMA). The original CVHM2 model simulated monthly groundwater budgets from 1961 to 2019. This data release extends the simulation period to the...
MODPATH Model Used to Evaluate Flowpaths from Two Contaminant Plume Source Areas near Joint Base Cape Cod, Western Cape Cod, Massachusetts MODPATH Model Used to Evaluate Flowpaths from Two Contaminant Plume Source Areas near Joint Base Cape Cod, Western Cape Cod, Massachusetts
The U.S. Geological Survey (USGS) used an existing groundwater flow model to determine steady-state groundwater flowpaths from two contaminant plume source areas by using a particle tracking post-processing model (MODPATH; Pollock, 2012) as part of an assessment of potential contaminant discharge at the coast in Bourne, Massachusetts. The extents of the source areas, originating from two...
Molokaʻi forest bird malaria infection data 2003 Molokaʻi forest bird malaria infection data 2003
This data publication contains information collected as part of a field and laboratory effort to determine prevalence of avian malaria (Plasmodium relictum) and pox-like lesions (Avipoxvirus spp.) in native and non-native forest birds on Molokaʻi in the Hawaiian Islands. Forest bird banding data, observations of pox-like lesions and blood samples for diagnosis of Plasmodium relictum, the...
Monotonic Trends in Modelled Water Supply for Select Outputs from NHM-PRMS models for Hawaii, Puerto Rico, and the US Virgin Islands Monotonic Trends in Modelled Water Supply for Select Outputs from NHM-PRMS models for Hawaii, Puerto Rico, and the US Virgin Islands
This dataset contains the Mann-Kendall p value, Theil - Sen slope estimate, summary statistics for eleven modelled water budget components simulated by the National Hydrologic Model Precipitation-Runoff Modeling System (NHM-PRMS) (Markstrom and others, 2024). The trend analyses are created from aggregated outputs from three separate models, each of which was forced with Daymet Version 4...
